What is the 10 question d in the geography of the college entrance examination? Question 1 1 is it a? Please explain the reason, thank you!

AC is obviously ruled out, so I won't say much. It has been said in the definition that spring is divided into 0 degrees, and there are 24 knots here, so 360 ÷ 24 = 15, so each solar term spans 15, and there are1/kloc between the vernal equinox and the millennium, so1/kloc.

Question 1 1: The same day means that the latitude of the direct point of the sun is the same. Grain Rain is probably after Tomb-Sweeping Day, if it is April 4th.

Therefore, the latitude of the same straight point as April 4 is within the range of (summer solstice and autumnal equinox), and the first frost can be calculated by combining the distance from the vernal equinox.
