A graph shows outdoor temperature from noon to midnight. From
6 p.m. to midnight, the temperature drops from 75 degrees to 60
degrees. Is the temperature negative at any point during this
interval?

Yes -- since the graph is going down, the temperature must be dropping below zero.

Yes, but only exactly at midnight.

No -- the temperature is decreasing, but it stays positive (from 75 down to 60) the whole time.

It cannot be determined from the description alone.
