PrepTest 33, Section 2, Question 8
Few animals brave the midday heat of the Sahara desert. An exception is the silver ant, which chooses this time of day to leave its nest and scout for food, typically the corpses of heat-stricken animals. Even the silver ant, however, must be careful: at such times they can become victims of the heat themselves.

Which one of the following, if true, LEAST helps to explain the silver ant's choice of scavenging times?
The chief predators of the silver ant must take cover from the sun during midday.
The cues that silver ants use to navigate become less reliable as the afternoon progresses.
Other scavengers remove any remaining corpses as soon as the temperature begins to drop in the afternoon.
The temperature inside the silver ants' nests often exceeds the surface temperature during the hottest times of the day.
Silver ants cool themselves by climbing onto small pieces of dried vegetation to take advantage of random light breezes.
