请你解出这个道题，并要用太阳视运动图进行可视化讲解，请详细地展现出逻辑链，以便我理解---来自天津的小明正在M地旅行,他给家中的妈妈发了微信。左图为当时妈妈的手机截屏,右图为此刻全球部分区域太阳高度分布图。据此完成下面小题。 **WeChat Screenshot:** Time: 20:00 [Play icon] [Phone icon] [Messages icon] < 18 小明 ... 小明 我正在大街上散步 [smiling face with open mouth and tightly-closed eyes emoji] [smiling face with open mouth and tightly-closed eyes emoji] 现在咱这大街景色也很美,华灯初上非常绚丽! 妈妈 **Solar Altitude Distribution Diagram:** Type: Concentric circle diagram representing solar altitude distribution. Main Elements: - Center: Labeled 90° (representing 90° solar altitude). - Concentric circles: Labeled with solar altitude values 75°, 60°, 45° outwards from the center. - Lines: Two perpendicular lines passing through the center, one vertical, one horizontal. - Label: "20°N" is labeled on the left side of the horizontal line. - Point: A black dot labeled 'M' is located on the vertical line above the center, approximately one-quarter of the distance from the 90° center to the 75° circle. **Question 11:** 小明旅行的M地可能是（ ） A. 东京 B. 悉尼 C. 伦敦 D. 巴西利亚 **Question 12:** 与M地二至日正午阳光照射情况最为相符的是（ ） Options are represented by diagrams labeled A, B, C, D. **Diagrams for Question 12:** Each diagram shows: - A horizontal line labeled 'N' on the left and 'S' on the right, representing the ground surface. - A number inside a circle below the ground line (1, 2, 3, or 4). - A line segment representing a sun ray coming from above and hitting the ground. - An angle labeled "46°52'" between the sun ray and the horizontal ground line. This angle represents the solar altitude. - Diagram A (labeled 1 below): Sun ray comes from the upper right, angle 46°52' is on the North side of the point where the ray hits the ground. The ray points towards North. - Diagram B (labeled 2 below): Sun ray comes from the upper left, angle 46°52' is on the South side of the point where the ray hits the ground. The ray points towards South. - Diagram C (labeled 3 below): Sun ray comes vertically downwards, but is tilted slightly. The angle 46°52' is marked between the sun ray and the vertical line perpendicular to the ground, which is incorrect representation of solar altitude. Assuming the angle 46°52' is intended as solar altitude, the diagram shows a ray coming from the upper right, with the angle marked between the ray and the vertical, implying the zenith angle is 46°52', so altitude is 90 - 46°52'. However, the label explicitly says 46°52' is the altitude. Let's assume the angle marked between the sun ray and the horizontal is 46°52'. In diagram C, the sun ray comes from the upper right, and the angle 46°52' is marked on the North side with respect to the horizontal. The diagram looks very similar to diagram A, but the angle marking relative to the vertical line is confusingly also present but unlabeled. Let's go by the angle marked against the horizontal ground. - Diagram D (labeled 4 below): Sun ray comes from the upper left, angle 46°52' is marked on the South side of the point where the ray hits the ground. The diagram looks very similar to diagram B. Let's assume the angle marked against the horizontal ground is 46°52'. Based on common representation: - Diagrams A and C show the sun is in the North direction at noon (relevant for Southern Hemisphere or Northern Hemisphere locations south of subsolar point). The angle 46°52' is the solar altitude. - Diagrams B and D show the sun is in the South direction at noon (relevant for Northern Hemisphere locations north of subsolar point). The angle 46°52' is the solar altitude.
