Question

hoarding resources is just one of the ways in which the dromedary camel copes with desert conditions. blazing desert heat, upwards of 120°f, can present challenges as well, but the camels particularly long legs keep its big body high off the hot ground—providing a natural form of air conditioning. another adaptation for staying off the ground comes into play when the camel is at rest. although seemingly settled down with its legs folded under itself, the camel uses a pillow - like callus under its chest to both balance its body and keep its belly off the hot sand. other demands of the desert are also dealt with handily. for instance, in the event of a sandstorm, the camel can actually close its nostrils to keep out dust while its eyes are protected by long eyelashes. furthermore, its eyes are shielded with an extra eyelid that functions something like a windshield wiper to dislodge particles; this eyelid is so thin that, even when closed, it can be seen through.

1. which of the following best expresses the main idea of this paragraph?

e. the camels long eyelashes protect its eyes, and an extra eyelid operates a wiper to clear particles that gather near the eyes.
f. to survive in the deserts heat, the dromedary camel has developed adaptations in several body parts, including its legs, eyelids, and nostrils.
g. hoarding resources is a key way in which dromedary camels have adapted to the harsh conditions of the desert.
h. the camels long legs act as a natural air conditioner by keeping the camels belly away from the hot ground, and the camel can rest on its folded legs to protect its chest from hot ground as well.

Explanation:

The paragraph discusses multiple adaptations (long legs, callus under chest, ability to close nostrils, long eyelashes, extra eyelid) of the dromedary camel to desert conditions. Option F encompasses all these adaptations (legs, eyelids, nostrils) as a means of survival in the desert heat. Option E only focuses on eye - related adaptations. Option G only mentions hoarding resources (which is just one point in the paragraph). Option H only focuses on leg - related adaptations.

Answer:

F. To survive in the desert's heat, the dromedary camel has developed adaptations in several body parts, including its legs, eyelids, and nostrils.
