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.

Only this option is unrelated to the argument rest all option gives in support for the behaviour of the silver ants.

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. 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.

We need to find an answer option which least explains the silver ant's choice of scavenging times(in the afternoon when it is extremely hot)

(A) The chief predators of the silver ant must take cover from the sun during midday.
If their chief predators take cover, the ants would have one less problem to take care of.
(B) The cues that silver ants use to navigate become less reliable as the afternoon progresses.
If the navigability becomes weaker as the day progresses,
it makes sense to venture out in the open, when their navigation is at the best

(C) Other scavengers remove any remaining corpses as soon as the temperature begins to drop in the afternoon.
It means less competition for the corpses, so is an added advantage to go out in the afternoon
(D) The temperature inside the silver ants’ nests often exceeds the surface temperature during the hottest times of the day.
They must be used to the heat out in the open, as their nests are very hot
(E) Silver ants cool themselves by climbing onto small pieces of dried vegetation to take advantage of random light breezes.
There is no clear link of the ants getting random light breezes and the choice of time to go scavenging.
This is our correct answer.

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