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?

(A) The chief predators of the silver ant must take cover from the sun during midday.
(B) The cues that silver ants use to navigate become less reliable as the afternoon progresses.
(C) Other scavengers remove any remaining corpses as soon as the temperature begins to drop in the afternoon.
(D) The temperature inside the silver ants’ nests often exceeds the surface temperature during the hottest times of the day.
(E) Silver ants cool themselves by climbing onto small pieces of dried vegetation to take advantage of random light breezes.

Which one of the following, if true, LEAST helps to explain the silver ant’s choice of scavenging times?

(A) The chief predators of the silver ant must take cover from the sun during midday. the ant would have to avoid the predators and thus this explains why they go out in the midday.
(B) The cues that silver ants use to navigate become less reliable as the afternoon progresses. after the midday the navigation for the ants become difficult and thus they choose to go out in the mid day.explains the reason.
(C) Other scavengers remove any remaining corpses as soon as the temperature begins to drop in the afternoon.the ants must get to the place befoere other scavangers can take their share and since the others come after the midday the ants have to reach in midday.
(D) The temperature inside the silver ants’ nests often exceeds the surface temperature during the hottest times of the day.the temp of the nest is higher than the outside tempratures and it would be better for the ants to go out rather than to stay in the hotter nest.
(E) Silver ants cool themselves by climbing onto small pieces of dried vegetation to take advantage of random light breezes. does not specifically says anything about why the ant go out in the midday, thus is the correct answer for the question asked.

+1 E

No link to specific time to gather food.They could cool themselves any time of the day,if true.
