Which person in the high-rise building is closest to the street level

Step-by-step explanation:

To solve this problem, we need to take the street level as reference, that is, it's gonna be level zero.

So, the nearest person to zero is the answer.

According to the problem,

Moira is on the fourth floor.

Geoffrey is between the second and third floor.

Sandy is on the -2 basement floor.

Hasim is between -1 and -2 levels

If we compare this, we find that Moira is tha farest person, followed by Geoffrey.

Therefore, if Hasim is between -1 and -2 levels, then he is the nearest person to zero level, that is, to street level, because this interval is closer that -2 basement floor where is sandy.
