A high school geography problem (about weather system) has extra points. Thank you.

On the three-dimensional map, the warm air mass is above the front and the cold air mass is below; The front height on the left (mostly far from the ground) is a warm front-the front moves to the left, so 1 is in front of the warm front and 2 is behind it; The picture on the right (mostly near the ground) is a cold front-the front moves to the left, so 4 is in front of the cold front and 6 is behind it.

22. The triangle is a cold front: A is a cold front and moves to the lower right. 1 In front of the cold front, A is wrong; B is a cold front, moving to the lower left. After the cold front, B was wrong. The semicircle is a warm front: C is a warm front and moves upward, 4 is in front of the warm front, and C is wrong; D is the warm front and moves to the lower right, 6 is the back of the warm front, and D is wrong.

So the title of this question is wrong.
