单选题 If the figure below on the left was folded together it would make a box. Imagine the box is made of paper or card, so that you cannot see through it. You have to say which of the alternatives would be made from the unfolded figure on the left.

【正确答案】 A

【答案解析】在左图中，把左边的第一个方块作为底边时，带黑色三角的方块在旁边出现，因而可知A图正确。
