The passage given below is followed by four alternate summaries. Choose the option that best captures the essence of the passage.
Question 29 : North American walnut sphinx moth caterpillars (Amorpha juglandis) look like easy meals for birds, but they have a trick up their sleeves — they produce whistles that sound like bird alarm calls, scaring potential predators away. At first, scientists suspected birds were simply startled by the loud noise. But a new study suggests a more sophisticated mechanism: the caterpillar's whistle appears to mimic a bird alarm call, sending avian predators scrambling for cover. When pecked by a bird, the caterpillars whistle by compressing their bodies like an accordion and forcing air out through specialized holes in their sides. The whistles are impressively loud — they have been measured at over 80 dB from 5 cm away from the caterpillar — considering they are made by a two-inch long insect.
The paragraph explains how North American walnut sphinx moth caterpillars scare off bird predators: the caterpillar's whistle appears to mimic a bird alarm call, sending avian predators scrambling for cover.
Option 1 talks of a ‘specialized vocal tract’ which is not mentioned in the paragraph. Option 2 is incorrect as explained in the paragraph; it is not the loudness of the noise but the fact that it mimics a bird alarm call that frightens away the birds. Option 4 mentions ‘camouflage’, which is not discussed in the paragraph.
Choice C is the correct answer.
