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

Moira is in her doctor’s office on the fourth floor.
Geoffrey is in the elevator between the second and third floors.
Sandy is in the laundry room on the –2 basement floor.
Hasim is leaving the parking garage and is currently between –1 and –2 levels.

To determine which person in the high-rise building is closest to the street level, we need to compare the floor levels where each person is currently located.

Since Sandy is in the laundry room on the –2 basement floor, it means she is two floors below ground level.

Hasim is leaving the parking garage and is currently between –1 and –2 levels, which means he is also below ground level.

Geoffrey is in the elevator between the second and third floors, which would put him a few floors above ground level.

Finally, Moira is in her doctor's office on the fourth floor, indicating that she is the farthest from the street level.

Therefore, the person closest to the street level is either Sandy or Hasim, depending on their exact locations within the basement floors.
