**Question Stem:**
1. 从所给的四个选项中选择最合适的一个填入问号处, 使之呈现一定的规律 ( )。
(1. From the given four options, choose the most suitable one to fill in the question mark, so that it shows a certain pattern ( ).)
**Chart/Diagram Description:**
The problem presents a sequence of four images, followed by four option images. Each image is a regular hexagon divided into six equal triangular sectors by lines originating from the center to the vertices. The sectors contain a certain number of black circles (●), white circles (○), or are empty.
**Sequence of Images (Top Row):**
There are four images in the top row, from left to right, followed by a question mark in the fourth position.
Let's label the sectors S1 to S6 starting from the top sector and going clockwise.
* **Image 1:**
* S1: Empty
* S2: 3 White circles (○○○)
* S3: 2 Black circles (●●)
* S4: 1 Black circle (●)
* S5: 3 Black circles (●●●)
* S6: 2 White circles (○○)
* **Image 2:**
* S1: 2 Black circles (●●)
* S2: Empty
* S3: 3 White circles (○○○)
* S4: 2 White circles (○○)
* S5: 3 Black circles (●●●)
* S6: 1 Black circle (●)
* **Image 3:**
* S1: 3 Black circles (●●●)
* S2: 2 Black circles (●●)
* S3: Empty
* S4: 3 White circles (○○○)
* S5: 2 White circles (○○)
* S6: 1 Black circle (●)
* **Image 4:** Contains a question mark (?).
**Options (Bottom Row):**
There are four option images labeled A, B, C, and D from left to right. Let's label the sectors S1 to S6 starting from the top sector and going clockwise for each option.
* **Option A:** (Labeled A below the image)
* S1: Empty
* S2: 3 Black circles (●●●)
* S3: 2 White circles (○○)
* S4: 3 White circles (○○○)
* S5: 2 Black circles (●●)
* S6: 1 Black circle (●)
* **Option B:** (Labeled B below the image)
* S1: 1 Black circle (●)
* S2: Empty
* S3: 3 Black circles (●●●)
* S4: 2 White circles (○○)
* S5: 3 White circles (○○○)
* S6: 2 Black circles (●●)
* **Option C:** (Labeled C below the image)
* S1: 2 Black circles (●●)
* S2: 1 Black circle (●)
* S3: Empty
* S4: 3 Black circles (●●●)
* S5: 2 White circles (○○)
* S6: 3 White circles (○○○)
* **Option D:** (Labeled D below the image)
* S1: 3 White circles (○○○)
* S2: 2 Black circles (●●)
* S3: 1 Black circle (●)
* S4: Empty
* S5: 3 Black circles (●●●)
* S6: 2 White circles (○○)
**Observed Pattern (for context):**
Observing the sequence of images, the empty sector appears to move one position clockwise in each step. The empty sector is in S1 in Image 1, S2 in Image 2, and S3 in Image 3. Following this pattern, the empty sector in the missing image (Image 4) should be in S4. Option D is the only option where sector S4 is empty.
