( ) **Options:** A. [Image of a butterfly] B. [Image of a bee] C. [Image of a frog] D. [Image of a snail] E. [Image of a worm] **Chart/Diagram Description:** * **Type:** Grid/Maze diagram representing a path on a checkered surface. * **Main Elements:** * **Grid:** A rectangular grid consisting of squares, alternating light and dark shading. * **Icons:** * House: Located in the bottom left corner. * Ant: Located next to the house. * Ladybug: Located in the top right section, at the end of the first path. * Butterfly: Located in the top right corner. * Bee: Located in the top left section. * Frog: Located in the middle right section. * Snail: Located in the middle left section. * Worm: Located in the bottom left section. * **Paths:** Two distinct paths indicated by black arrows on a white background, overlaid on the grid. * **Path 1:** Starts at the Ant/House, goes right 3 squares, up 3 squares, right 3 squares, up 1 square. This path ends at the Ladybug. * **Path 2:** Starts at the Ant/House, goes right 2 squares, down 2 squares, right 3 squares, up 3 squares, right 2 squares, up 2 squares. * **Labels/Annotations:** Arrows indicate direction and the numbers next to the arrows indicate the number of squares to move in that direction. * **Relative Position:** The house/ant is at the bottom left. The ladybug and butterfly are towards the top right. The bee is towards the top left. The worm is near the bottom left. The snail is in the middle left. The frog is in the middle right. **Tracing Path 2:** Starting from the house (assume the ant is at the house's location): 1. -> 2: Move right 2 squares. 2. ↓ 2: Move down 2 squares. (The ant is already at the bottom row, so moving down is not possible within the depicted grid area below the ant's starting position. Assuming "down" means moving towards the bottom of the grid, and the starting position is in the bottom left corner area, the grid seems to extend below. Let's assume the starting row is above the visible bottom row where the worm is. Based on the visual, the house/ant is on the third row from the bottom. So, from row 3, going down 2 would reach row 1.) Let's re-evaluate based on the first path. The first path starts at the house/ant and goes right 3, up 3, right 3, up 1 to reach the ladybug. Let's assign coordinates. Let the square to the immediate right of the house be (1,0) relative to the house (0,0). The grid seems to be laid out like a chessboard. Let's assume the house is at a starting point. From the image, the house is in a square. Let's say the ant starts in this square. * Path 1: From starting square: -> 3 (3 squares right), ↑ 3 (3 squares up), -> 3 (3 squares right), ↑ 1 (1 square up). This reaches the ladybug. Let's visually trace this on the grid. Start at the house square. Count 3 squares right, then 3 squares up, then 3 squares right, then 1 square up. This does indeed end at the square containing the ladybug. * Path 2: From starting square (house): -> 2 (2 squares right), ↓ 2 (2 squares down), -> 3 (3 squares right), ↑ 3 (3 squares up), -> 2 (2 squares right), ↑ 2 (2 squares up). Let's trace this on the grid starting from the house square. 1. Right 2 squares. 2. Down 2 squares. (Need to assume the grid extends downwards). Visually tracing, if we move down 2 from the house's row, we reach the row where the worm is located. 3. Right 3 squares. From the position after step 2, move right 3 squares. 4. Up 3 squares. From the position after step 3, move up 3 squares. Visually tracing this, it seems to end up near the snail. 5. Right 2 squares. From the position after step 4, move right 2 squares. 6. Up 2 squares. From the position after step 5, move up 2 squares. Let's assign coordinates starting from the bottom-left square of the visible grid as (1,1). The worm is at (3,1). The frog is at (8,2). The snail is at (4,3). The house/ant is at (1,3). The bee is at (3,6). The ladybug is at (8,6). The butterfly is at (9,7). Starting at the house (1,3): 1. -> 3: (1+3, 3) = (4,3). This is the snail. (This is the first path's start). Path 1 corrected trace from (1,3): ->3 -> (4,3); ↑3 -> (4, 3+3)=(4,6); ->3 -> (4+3, 6)=(7,6); ↑1 -> (7, 6+1)=(7,7). Wait, the ladybug is at (8,6). The path shown on the diagram is Right 3, Up 3, Right 3, Up 1. Let's count squares from the diagram starting at the house icon. Starting square of the house: Count 3 squares to the right, then 3 squares up, then 3 squares to the right, then 1 square up. This path on the diagram visually ends at the square with the ladybug. Let's re-trace Path 2 visually from the house icon square: 1. -> 2: Move 2 squares to the right. 2. ↓ 2: Move 2 squares down. 3. -> 3: Move 3 squares to the right. 4. ↑ 3: Move 3 squares up. 5. -> 2: Move 2 squares to the right. 6. ↑ 2: Move 2 squares up. Visually tracing Path 2 on the diagram: Start at the house square. 1. Go 2 squares right. 2. Go 2 squares down (you reach the row below the snail, in the column 2 steps right from the house column). 3. Go 3 squares right. 4. Go 3 squares up. (From the row below the snail, you go up 3 rows). This lands you on the row of the snail, and then two rows above the snail's row. 5. Go 2 squares right. 6. Go 2 squares up. Let's try using the grid lines as boundaries for squares. Let the bottom-left corner of the house square be the origin (0,0). Each square has size 1x1. The house occupies a square. Let the ant start at the center of the house square. Let's assume moves are relative to the grid lines. Let the vertical lines be x=0, 1, 2, ... and horizontal lines be y=0, 1, 2, ... Let's assume the bottom-left corner of the grid is (0,0). The house appears to be in the square defined by x=[0,1], y=[2,3]. Let's say the starting point is the center of the house square, (0.5, 2.5). This coordinate system doesn't seem helpful with the arrow notation and counting squares. Let's go back to counting squares on the visual grid. Let the house be in the starting square. Path 1: From Start square -> 3 squares Right, then 3 squares Up, then 3 squares Right, then 1 square Up. This ends at the Ladybug square. This path is drawn on the grid and clearly connects the house/ant to the ladybug. Path 2: From Start square (House) -> 2 squares Right, then 2 squares Down, then 3 squares Right, then 3 squares Up, then 2 squares Right, then 2 squares Up. Trace on the grid: 1. From house square, move 2 squares right. 2. From there, move 2 squares down. This position is in the row where the worm is, 2 columns to the right of the house column. 3. From there, move 3 squares right. This position is still in the worm's row, 5 columns to the right of the house column. 4. From there, move 3 squares up. This position is 3 rows above the worm's row, 5 columns to the right of the house column. This lands you in the square with the Frog. 5. From there, move 2 squares right. This position is 2 columns to the right of the Frog's column, in the Frog's row. 6. From there, move 2 squares up. This position is 2 rows above the Frog's row, 2 columns to the right of the Frog's column. Let's re-examine the image carefully and trace Path 2's drawn arrows, which correspond to the instructions. There are no drawn arrows for Path 2. We must follow the textual instructions using the grid. Start at the square with the house/ant. 1. Move 2 squares right. You are now in the 3rd column from the left (if the house is in the 1st). 2. Move 2 squares down. From the house's row (let's call it row 3, counting from bottom = row 1), moving down 2 gets you to row 1. You are in the 3rd column, 1st row. The worm is in the 3rd column, 1st row. So, after ->2, ↓2, you reach the worm. 3. Move 3 squares right. From the worm's position, move 3 squares right. You are now in the 6th column, 1st row. 4. Move 3 squares up. From there, move 3 squares up. You are now in the 6th column, 4th row. The snail is in the 4th column, 3rd row. The frog is in the 8th column, 2nd row. The bee is in the 3rd column, 6th row. The ladybug is in the 8th column, 6th row. The butterfly is in the 9th column, 7th row. Let's rethink the numbering/coordinates. Let the house be at (0,0). Right is +x, Up is +y. Path 1: (0,0) -> (+3,0) -> (+3,+3) -> (+3+3,+3) -> (+6,+3) -> (+6,+3+1) -> (+6,+4). This ends at the ladybug's position relative to the house. Let's see where the ladybug is relative to the house. Visually, starting from the house, the ladybug is 6 squares right and 4 squares up. So the notation matches the first path ending at the ladybug. Path 2: From (0,0): -> 2 (2 squares right), ↓ 2 (2 squares down), -> 3 (3 squares right), ↑ 3 (3 squares up), -> 2 (2 squares right), ↑ 2 (2 squares up). (0,0) -> (+2,0) -> (+2,-2) -> (+2+3,-2) -> (+5,-2) -> (+5,+3-2) -> (+5,+1) -> (+5+2,+1) -> (+7,+1) -> (+7,+1+2) -> (+7,+3). The final position is 7 squares right and 3 squares up from the house. Let's check the icons' positions relative to the house (0,0). Worm: 2 squares right, 2 squares down? No, visually the worm is 2 squares right and 2 squares down from the house if we consider the bottom row as the starting point for counting down from the house's row. Let's re-evaluate the grid and counting. Let's treat the grid as a matrix. Let the house be in cell (Row 3, Col 1). Path 1: From (3,1): Right 3 -> (3, 1+3)=(3,4); Up 3 -> (3-3, 4)=(0,4); Right 3 -> (0, 4+3)=(0,7); Up 1 -> (0-1, 7)=(-1,7). This doesn't match the ladybug position. Let's go back to visual counting from the image, square by square. Start at the House square. Path 1: 3 squares Right, 3 squares Up, 3 squares Right, 1 square Up. Yes, this ends at the Ladybug square. Path 2: From House square: 1. -> 2: Move 2 squares right. 2. ↓ 2: Move 2 squares down. 3. -> 3: Move 3 squares right. 4. ↑ 3: Move 3 squares up. 5. -> 2: Move 2 squares right. 6. ↑ 2: Move 2 squares up. Let's trace this path again on the image. Start at the House. 1. Move 2 squares to the right. You are in the 3rd square horizontally from the start. 2. Move 2 squares down. You are now in the row containing the worm, in the 3rd square from the left. This is exactly the position of the **Worm**. 3. Move 3 squares right. 4. Move 3 squares up. 5. Move 2 squares right. 6. Move 2 squares up. The question asks "Which animal would it come to, if it goes from home following these arrows...". It seems the question is asking what is at the *final* destination of the path, not necessarily intermediate points. However, the phrase "it comes to the ladybug" for the first path implies reaching the destination. Let's re-trace Path 2 completely to its final destination. Start at the House. 1. Right 2 squares. 2. Down 2 squares. (You are now at the Worm's square). 3. Right 3 squares. 4. Up 3 squares. (From the worm's row, go up 3 rows). This lands you in the row where the snail is, and then 2 rows above that. This brings you to the row above the snail's row, in the column 3 steps right from the worm's column. 5. Right 2 squares. 6. Up 2 squares. Let's count the columns and rows properly. Let the house square be (1,1) in a local grid numbering just for counting moves. This is difficult without clear grid lines or labels. Let's use the provided image grid itself. Let's say the house is in cell (R,C). Path 1: (R,C) -> Right 3 -> (R, C+3) -> Up 3 -> (R-3, C+3) -> Right 3 -> (R-3, C+3+3) = (R-3, C+6) -> Up 1 -> (R-3-1, C+6) = (R-4, C+6). This is the location of the Ladybug. Visually, the Ladybug is 4 rows above the house and 6 columns to the right. So, if house is at (R,C), Ladybug is at (R-4, C+6). Path 2: From (R,C): 1. -> 2: (R, C+2) 2. ↓ 2: (R+2, C+2) (Assuming down increases the row index) 3. -> 3: (R+2, C+2+3) = (R+2, C+5) 4. ↑ 3: (R+2-3, C+5) = (R-1, C+5) 5. -> 2: (R-1, C+5+2) = (R-1, C+7) 6. ↑ 2: (R-1-2, C+7) = (R-3, C+7) The final position is 3 rows up and 7 columns right from the house. Let's check the positions of the animals relative to the house (R,C), counting squares right (+) and up (-). House: (R,C) Worm: Down 2, Right 2 -> (R+2, C+2)? No, visually the worm is 2 squares right and 2 squares down. If the house is (3,1), the worm is at (1,3) according to the coordinates I tried earlier (bottom-left (1,1)). Let's retry using the visual grid again. Let's assume the squares are numbered like a spreadsheet, starting from the top left. This doesn't match the instructions (ant starts from home in bottom left). Let's trust the first path works and use it to calibrate. Starting at the house square. Path 1: R3, U3, R3, U1 ends at Ladybug. Let's assign coordinates starting from the bottom-left visible square as (1,1). Worm is at (3,1). Frog is at (8,2). Snail is at (4,3). House is at (1,3). Bee is at (3,6). Ladybug is at (8,6). Butterfly is at (9,7). Starting at House (1,3): Path 1: R3 -> (1+3, 3) = (4,3) (Snail); U3 -> (4, 3+3)=(4,6); R3 -> (4+3, 6)=(7,6); U1 -> (7, 6+1)=(7,7). This ends at (7,7), but the ladybug is at (8,6). My coordinate system or interpretation of the diagram is off. Let's assume the moves mean number of *steps* between squares, and the icon is in a square. Let the starting square be S. Path 1: S -> R3 -> U3 -> R3 -> U1. Ends at Ladybug square. Let's verify on the image. Start at House square. Move 3 squares right, 3 squares up, 3 squares right, 1 square up. Yes, this lands exactly on the Ladybug square. Path 2: From S: -> 2, ↓ 2, -> 3, ↑ 3, -> 2, ↑ 2. Start at House square. 1. Move 2 squares right. 2. Move 2 squares down. 3. Move 3 squares right. 4. Move 3 squares up. 5. Move 2 squares right. 6. Move 2 squares up. Let's trace carefully on the image again. Start at the House. 1. Go 2 squares right. You are in the 3rd column. 2. Go 2 squares down. You are in the 1st row (where the worm is). You are in the square with the Worm. 3. Go 3 squares right. You are now in the 6th column, 1st row. 4. Go 3 squares up. You are now in the 6th column, 4th row. 5. Go 2 squares right. You are now in the 8th column, 4th row. 6. Go 2 squares up. You are now in the 8th column, 6th row. This is the location of the Ladybug. Let's recheck my visual trace. House: Assume it's at (1,1) in a grid where columns are 1 to 9 from left to right, and rows are 1 to 7 from bottom to top. House: (1,1). Worm: (3,1). Frog: (8,2). Snail: (4,3). Bee: (3,6). Ladybug: (8,6). Butterfly: (9,7). Path 1: From (1,1): R3 -> (4,1); U3 -> (4,4); R3 -> (7,4); U1 -> (7,5). This does not reach (8,6). Let's assume the icons are in the squares. Let's count the number of squares moved, not the final coordinate. Start at House. Path 1: Move Right 3 squares. Then move Up 3 squares. Then move Right 3 squares. Then move Up 1 square. The final square is the Ladybug square. This is consistent with the diagram. Path 2: From House: 1. Move Right 2 squares. 2. Move Down 2 squares. 3. Move Right 3 squares. 4. Move Up 3 squares. 5. Move Right 2 squares. 6. Move Up 2 squares. Let's carefully count the squares on the diagram from the House icon's square. Start at the House square. 1. Move 2 squares to the right. You are in the 3rd square from the left, in the House's row. 2. Move 2 squares down. You are now in the 3rd square from the left, 2 rows below the House's row. This square contains the **Worm**. 3. Move 3 squares to the right. You are now in the 6th square from the left, in the Worm's row. 4. Move 3 squares up. You are now in the 6th square from the left, 3 rows above the Worm's row. 5. Move 2 squares to the right. You are now in the 8th square from the left, in the row from step 4. 6. Move 2 squares up. You are now in the 8th square from the left, 2 rows above the row from step 5. Let's visually check the final position. Starting from the Worm (after step 2), go Right 3, Up 3, Right 2, Up 2. From Worm: R3 -> U3 -> R2 -> U2. Tracing from Worm: R3 -> square (6th col, 1st row). U3 -> square (6th col, 4th row). R2 -> square (8th col, 4th row). U2 -> square (8th col, 6th row). The square at (8th col, 6th row) is the square with the **Ladybug**. Let me re-read the first sentence again: "When the ant goes from home following these arrows: -> 3, ↑ 3, -> 3, ↑ 1, **it comes to the ladybug**". This means the end point is the ladybug. My trace of Path 1 visually on the diagram ended at the ladybug. My second trace of Path 2 visually on the diagram also ended at the ladybug. There must be a mistake in my trace or interpretation. Let's use the image as the definitive map. Count squares from the house. House location: Bottom left area. Path 1: From House, R3, U3, R3, U1. Trace this path drawn on the grid. It ends at the Ladybug. This verifies the starting point (House) and ending point (Ladybug) for Path 1. Now, trace Path 2: From House, R2, D2, R3, U3, R2, U2. Start at the House square. 1. Move 2 squares Right. 2. Move 2 squares Down. (You land on the square with the **Worm**). 3. Move 3 squares Right. 4. Move 3 squares Up. 5. Move 2 squares Right. 6. Move 2 squares Up. Let's trace again, paying close attention to the visual grid lines and squares. Starting at the house square. R2: Move right 2 squares. D2: Move down 2 squares. You arrive at the square containing the **Worm**. R3: From the worm, move right 3 squares. U3: From there, move up 3 squares. This puts you in the square containing the **Snail**. R2: From the snail, move right 2 squares. This puts you in the square containing the **Frog**. U2: From the frog, move up 2 squares. This puts you in the square containing the **Ladybug**. Let me re-trace Path 2 again carefully: Start at House. 1. R2: Move 2 squares to the right. 2. D2: Move 2 squares down. You are at the square with the Worm. 3. R3: From the Worm, move 3 squares right. 4. U3: From that position, move 3 squares up. This path takes you through the snail's square and ends 1 row above the snail's row, 1 column to the right of the snail's column. Let me verify the coordinates again. Let the house be at (0,0). R+, D-, U+, L-. Path 1: (0,0) -> (3,0) -> (3,3) -> (6,3) -> (6,4). Ladybug is at (6,4) relative to the house. Path 2: (0,0) -> (2,0) -> (2,-2) -> (2+3,-2)=(5,-2) -> (5,-2+3)=(5,1) -> (5+2,1)=(7,1) -> (7,1+2)=(7,3). The final position is (7,3) relative to the house. Let's use the grid cell index. Let the bottom-left cell be (1,1). House: (1,3). Worm: (3,1). Snail: (4,3). Frog: (8,2). Bee: (3,6). Ladybug: (8,6). Butterfly: (9,7). Path 1 from (1,3): R3 -> (1+3, 3) = (4,3) (Snail); U3 -> (4, 3+3)=(4,6); R3 -> (4+3, 6)=(7,6); U1 -> (7, 6+1)=(7,7). This does not match Ladybug (8,6). There is an inconsistency between the diagram and the description of the first path ending at the ladybug, or my interpretation of the grid. Let's assume the diagram and the first path ending at the ladybug are correct, and use the visual tracing as the primary method. Path 1: Start at House -> R3, U3, R3, U1 -> Ends at Ladybug. This is shown by the black arrow path. Path 2: Start at House -> R2, D2, R3, U3, R2, U2. Trace this visually on the grid. From House: 1. Move 2 squares right. 2. Move 2 squares down. You arrive at the square with the **Worm**. 3. Move 3 squares right from the Worm's square. 4. Move 3 squares up from there. This brings you to the square with the **Snail**. 5. Move 2 squares right from the Snail's square. This brings you to the square with the **Frog**. 6. Move 2 squares up from the Frog's square. This brings you to the square with the **Ladybug**. Okay, tracing it step-by-step visually seems consistent now. The final destination of Path 2 is the Ladybug. Let's double check the options. The options show different animals. The question asks which animal is met at the *end* of the path. My visual tracing of Path 2 ends at the Ladybug. However, the problem states that Path 1 ends at the Ladybug. It seems highly unlikely that Path 2 would also end at the Ladybug and that the question is asking "Which animal is at the end of Path 2?" if the answer is the same as the end of Path 1, and the Ladybug is not one of the options. Let's re-read the question and options. Maybe the question is asking which animal is encountered *along* the path, or the *first* animal encountered, or maybe I am misinterpreting the moves. The question asks "Which animal would it come to". Let's re-evaluate the coordinates based on the first path being correct. Let the House be at (x_h, y_h). Ladybug is at (x_l, y_l). x_l = x_h + 3 + 3 = x_h + 6 y_l = y_h + 3 + 1 = y_h + 4 So, Ladybug is 6 units right and 4 units up from the House. This matches my earlier calculation relative to (0,0). Let's calculate the end point of Path 2 starting from (x_h, y_h). (x_h, y_h) -> R2 -> (x_h+2, y_h) -> D2 -> (x_h+2, y_h-2) -> R3 -> (x_h+2+3, y_h-2) = (x_h+5, y_h-2) -> U3 -> (x_h+5, y_h-2+3) = (x_h+5, y_h+1) -> R2 -> (x_h+5+2, y_h+1) = (x_h+7, y_h+1) -> U2 -> (x_h+7, y_h+1+2) = (x_h+7, y_h+3). The final position is (x_h+7, y_h+3). Now let's find which animal is at (x_h+7, y_h+3) relative to the house. It's 7 units right and 3 units up from the house. Let's visually count 7 squares right and 3 squares up from the House square. From House, move 7 squares right, then 3 squares up. Right 7 squares from House. Up 3 squares from House. This lands on the square containing the **Frog**. Let's check the relative positions of other animals from the house (visual counting): Worm: R2, D2. (x_h+2, y_h-2) Snail: R3, U0? No. Visually the snail is R3, U2 from the worm. R (2+3)=5, D (2-3)=-1? Let's trust the coordinate calculation using the moves from the house. End of Path 2 is (x_h+7, y_h+3). This is 7 units right, 3 units up from the house. Let's visually verify the Frog's position relative to the House. From the House square, move 7 squares right and 3 squares up. Yes, this lands on the square with the Frog. So, the animal encountered at the end of the second path is the Frog. Let's check the options again: A. Butterfly B. Bee C. Frog D. Snail E. Worm The calculated endpoint matches the Frog, which is option C. Let's quickly check the visual positions of the other animals relative to the house: Worm: R2, D2 -> (x_h+2, y_h-2) - Matches calculation. Snail: R3, U0? From house, R3, U0 is in the same row as the house, 3 squares right. Snail is clearly above the house's row. Let's count from the house: R3, U2. So Snail is at (x_h+3, y_h+2). My earlier visual count R3, U3 was wrong. Frog: R7, U3. Matches my calculation for the end of Path 2. Bee: R2, U3. From house, R2, U3. (x_h+2, y_h+3). Ladybug: R6, U4. Matches my calculation from Path 1 description. Butterfly: R8, U4. From house, R8, U4. (x_h+8, y_h+4). Okay, the calculation based on coordinates relative to the house, where Right increases x, Up increases y, and moves are added, seems consistent with the diagram and the first path description. End of Path 2 is at (x_h+7, y_h+3). The animal at this position is the Frog. **Final check:** Path 1: House (0,0) -> R3(3,0) -> U3(3,3) -> R3(6,3) -> U1(6,4). Ladybug is at (6,4). Path 2: House (0,0) -> R2(2,0) -> D2(2,-2) -> R3(5,-2) -> U3(5,1) -> R2(7,1) -> U2(7,3). Final position is (7,3). Relative positions from House (0,0): Worm: R2, D2 -> (2,-2) Snail: R3, U2 -> (3,2) (Visual check: from house R3 U2 lands on snail) Frog: R7, U3 -> (7,3) (Visual check: from house R7 U3 lands on frog) Bee: R2, U3 -> (2,3) (Visual check: from house R2 U3 lands on bee) Ladybug: R6, U4 -> (6,4) (From Path 1 calculation) Butterfly: R8, U4 -> (8,4) (Visual check: from house R8 U4 lands on butterfly) The coordinates calculated from the moves match the visual positions of the animals relative to the house. The end of Path 2 is at (7,3) relative to the house, which is the location of the Frog. Let's double check the Snail, Bee, Butterfly positions visually again from the house. Snail: R3, U2. Yes. Bee: R2, U3. Yes. Butterfly: R8, U4. Yes. It seems my coordinate system and tracing are now consistent and correct. The final position of Path 2 is the Frog.
