There is a geography question in the college entrance examination. Please come over and have a detailed analysis. Thank you, heroes.

(1) In the diagram, point A represents the sunset position during the winter solstice (solar terms), and point B represents the sunset position during the vernal equinox or autumn equinox (solar terms). Analysis: the eastern part of China is located in the northern hemisphere, with the shortest winter solstice, the longest night and the earliest sunset; The summer solstice has the longest day, the shortest night and the latest sunset. Spring and autumn are equally divided day and night. The above answer can be obtained by combining the figure. ② Mark the north-south direction in the box in the figure. (Left is south, right is north) Analysis: ABC's sunset is west, so the opposite is east. According to "left west and right east, upper north and lower south", the answer is obtained. The answer of "left south and right east" given on the Internet is obviously the wrong answer. Are the South and the East antagonistic? Obviously not. ③ The longitude here is 132 E, and the longest day in a year is 15: 36. It can be inferred that this place may be located in (d) A. Jianghan Plain B. Chengdu Plain C. North China Plain D. Sanjiang Plain Analysis: The local sunset time is 18:00 in spring and autumn, while the Beijing time at point B in spring and autumn is 17: 12, with a time difference of 48 minutes and a longitude difference of four minutes, so Because the sunset is earlier than Beijing, it is in the east of Beijing. So the local longitude is120+12 =132 degrees. That is, 132 e. The longest day in a year is from summer to the sun, the sunset is 19:00 Beijing time, and the local time is 19+48= 19:48, so the length of a day is (19: 48. According to the longitude, only d matches, in the northeast.
