Geographical problems

The difference between February 2 1 and1October 2 1 is 8 months, and vice versa. The intermediate date is about June 2 1 or June 2 1, which is roughly the summer solstice or the winter solstice. The topic option is only summer solstice, so choose B.

From February 2 1 day to February 2 1 day of the year, sunlight can pass through the tunnel. What information can we get? Because the location of the temple is fixed, there are two dates when the sun can pass through the tunnel, which shows that the direct sunlight points on these two dates are the same. This topic is easy to understand. Only by finding a symmetrical date about the summer solstice can the direct point of the sun be located at the same latitude. If Ramses II's birthday is February1May, then the symmetrical date about the summer solstice is about July 2 1 July, so items B and D are excluded; The latitude of the temple is probably near the tropic of cancer, so the direct point of the sun on May 2 1 day is in the south, so it is judged that the tunnel entrance faces southeast. (About date symmetry, you can draw a picture if you don't understand it well)
