Answer 2

Answer:

B) You should stress the second syllable, because it is a verb that means to be stricken by an illness.

Explanation:

As a verb, to contract is stressed on the second syllable, and it in this case it means to catch a contagious disease. In that matter, the woman is said to be afraid to catch polio.

The rest of the alternatives are incorrect because, in the the sentence, contract is used as a verb following the conditional would. Besides, according  to the context, it does not mean to decrease in size o diminish.
