In order to clean up the plastic and pollution in the oceans, The Ocean Cleanup, a nonprofit foundation, has introduced The Interceptor 006, a barricade to prevent “trash tsunamis” in the Rio Motagua from entering into the Caribbean Sea. The barricade would capture plastic with heavy-duty floating booms on the surface of the water and allow water to flow freely below the surface through the fence.

Choice C is the best answer. The convention being tested is the use of verbs with modals. The modal “would” indicates possibility, ability, or necessity. In this choice, the verb “capture” is used correctly in conjunction with the following verb “allow” to describe what the barricade would do.

Choices A, B, and D: The past tense verb “allowed,” the present participle “allowing,” and the present tense verb “allows” cannot be used in this way with the modal “would” to describe what the barricade would do since it needs the base form of the verb.

✨ Expert's Tip ✨

A modal verb is used along with the base form of a verb to express possibility, ability, permission, command, or necessity.
If there are two verbs under one modal, the modal can be used once.
