请你用清晰的动画，给我讲解这个题是如何解出的，并且逻辑链要完整，让我理解---**Introductory Text:** The following figure shows the hourly changes in solar azimuth angle and altitude angle on a certain day at Zhongshan Station, Antarctica (69° 22′ S, 76° 22′ E). Among them, an azimuth angle of 0° (360°) represents due South, 90° represents due East, 180° represents due North, and 270° represents due West. Complete the following questions. **Chart Description:** Type: Line chart with two Y-axes showing the relationship between Local Time (X-axis) and two variables (Altitude Angle and Azimuth Angle) on the two Y-axes. X-axis: Labeled "当地时间/h" (Local Time/h), scale from 0 to 24 hours, marked every 4 hours. Left Y-axis: Labeled "高度角/°" (Altitude Angle/°), scale from 0° to 40°, marked every 10°. Represents the altitude angle, plotted with circles connected by lines. The altitude angle is 0° at time 0 and 24, reaches a maximum of slightly over 40° around time 12. Right Y-axis: Labeled "方位角/°" (Azimuth Angle/°), scale from 0° to 360°, marked every 60°. Represents the azimuth angle, plotted with filled squares connected by lines. The azimuth angle starts around 0°/360° at time 0, increases to 90° around time 6, 180° around time 12, 270° around time 18, and reaches 360° at time 24. Legend: —○— 高度角 (Altitude Angle) —■— 方位角 (Azimuth Angle) Azimuth Angle Reference: 0° (360°) is South, 90° is East, 180° is North, 270° is West. **Question 1:** Stem: 图示太阳高度角 10°时太阳朝向 ( ) (When the solar altitude angle is 10° in the figure, the sun is facing ( )) Options: A. 东南 (Southeast) B. 正东 (Due East) C. 东北 (Northeast) D. 正西 (Due West) **Question 2:** Stem: 该日最可能是 ( ) (This day is most likely ( )) Options: A. 1 月 1 日 (January 1st) B. 2 月 1 日 (February 1st) C. 3 月 1 日 (March 1st) D. 4 月 1 日 (April 1st)
