Leo: Given the sentence "Four people standing near a wall at night." is it true that "People stand by a wall while the moon is in the sky."?

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

The moon is in the sky so that means it is night.
Thus, the answer is yes.
