Directions for the following 1(one) question:

Read the following passage and answer the question that follows the passage. Your answer to the question must be based on the passage only.

North American walnut sphinx moth caterpillars (Amorpha juglandins) 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.

Q.35) What is the most logical and appropriate summary of the passage?

  1. North American walnut sphinx moth caterpillars will whistle periodically to ward off predator birds – they have a specialized vocal tract that helps them whistle.
  2. North American walnut sphinx moth caterpillars can whistle very loudly; the loudness of their whistles is shocking as they are very small insects.
  3. North American walnut sphinx moth caterpillars, in a case of acoustic deception, produce whistles that mimic bird alarm calls to defend themselves.
  4. North American walnut sphinx moth caterpillars, in a case of deception and camouflage, produce whistles that mimic bird alarm calls to defend themselves.
