Othefwtse. it risks being snapped up by a predator etevef-enough to take-advantage of its lowered defenses. The important parts here are it the arthropod risks being snapped up by a predator. Now our job is to find the answer choice that contains these elements and these elements only. Here are the choices again. A Arthropods are only vulnerable to predators during the period in which their shell is tender and easily penetrated.

We should have something that talks about arthropods. Eliminate this choice. Now look at C . It first mentions the weakened shell which matches with sentence 1. Next it says the arthropod cannot rely on its shell. At first this doesn t seem to match but sentence 2 stated that the creature must remain in hiding this is an example of not relying on its shell.
