Joanne and Emmanuel attend the same school but are in different grades and barely know each other. You would expect they would generally maintain which spatial distance?
a) 4 ft. to 12 ft.
b) 12 ft. to 25 ft.
c) 12 in. to 3 ft.
d) 18 in. to 4 ft.
Since they are in different grades they are likely in different classes, the only time their day would overlap might be in cafeteria or lunch time, and even then they wouldn't sit close to eachother.
