Question

which of the following sentences contains an error in subject - verb agreement? a the ocean is a majestic and mysterious place. b the sport of scuba diving lets people explores the beauty that lies beneath the surface of the ocean. c while under the water, scuba divers observe and swim with many different types of marine life. d while some people are afraid of sharks, scuba divers often consider it a special treat to see one of these graceful animals in their natural environment.

Explanation:

To determine the error in subject - verb agreement, we analyze each option:

• Option A: The subject "The ocean" (singular) and the verb "is" (singular) agree.
• Option B: The verb "lets" is a causative verb, and the structure "let sb. do sth." requires the base form of the verb after "sb.". Here, the subject of the infinitive - like structure after "lets people" should be "people" (plural), and the verb should be "explore" (base form), but it is "explores" (third - person singular), so there is a subject - verb agreement error.
• Option C: The subject "scuba divers" (plural) and the verbs "observe" and "swim" (plural) agree.
• Option D: The subjects "some people" and "scuba divers" (plural) and their respective verbs "are" and "consider" (plural) agree.

Answer:

B. The sport of scuba diving lets people explores the beauty that lies beneath the surface of the ocean.
