Question 1:C

Question 2:B

This topic investigates the length of day and night and the application of weather analysis.

Question 1: The sunrise and sunset time in the picture can be calculated that the day length in Wuhan is slightly longer than 12 hour, so it may be a dichotomy. Combined with the temperature, we can know that it is the autumnal equinox, so we choose C;

Problem 2: The daily temperature difference in this area is large, and when there is no wind, cloudy and windless, it is not conducive to the diffusion of pollutants. You can get mild sun protection on cloudy days, so option B is correct.
