Question:

Passage:

Insects' lives are very diminutive and they have many enemies, but they must survive long enough to rear and perpetuate their kind. The less insect-like they look, the better their probability of survival. To look "uneatable" by resembling or imitating plants is a deceit widely practised by insects. Mammals hardly ever use this kind of camouflage, but many fish and invertebrates do.

The stick caterpillar is well named. It is hardly discernible from a brown or green twig. This caterpillar is quite familiar and can be found almost anywhere in North America. It is also called "measuring worm" or "inchworm." It walks by arching its body, then stretching out and grasping the branch with its front feet then looping its body again to bring the hind feet forward. When danger threatens, the stick caterpillar stretches its body away from the branch at an angle and remains rigid and still, like a twig, until the danger has passed.

Walking sticks, or stick insects, do not have to assume a rigid, twig-like pose to find protection; they look like inedible twigs in any position. There are many kinds of walking sticks, ranging in size from the few inches of the North American variety to some tropical species that may be over a foot long. When at rest their front legs are stretched out, heightening their camouflage. Some of the tropical species are adorned with spines or ridges imitating the thorny bushes or trees in which they live. Leaves also seem to be a favorite object for insects to imitate. Many butterflies can suddenly disappear from view by folding their wings and sitting quietly among the foliage that they resemble.

The Correct Option is A

Solution and Explanation

Step 1: Look at how "camouflage" is used throughout the passage. It first appears in the sentence about insects trying "to look 'uneatable' by resembling or imitating plants", and later the passage talks about insects that "heighten their camouflage" by stretching their legs, being adorned with spines, or folding their wings to disappear among foliage.

Step 2: In every instance, camouflage is used to describe hiding or disguising oneself so predators cannot see or recognize the insect, which is the meaning of "to conceal".

Step 3: Reveal and divulge mean the opposite, to expose or make known, so they cannot be correct. Drop and entwine have no connection to hiding or disguise at all.

Step 4: The correct answer is Conceal.
