Question

passage 1
identifying sentences with correct usage
read each sentence. three of the sentences have at least one error in usage, but one of the sentences is correct. identify the correct sentence in each set.

• these kind of tomatoes are my favorite.
• speaking at the school assembly, our principal inferred that the juniors should volunteer more.
• my stepmother suggested that we clean the bathtub with the sorts of cleansers that is not abrasive.
• by saying that manuel was the best student in class, his biology teacher implied that manuel would receive an a in the course.

Explanation:

• First sentence: "These kind" should be "This kind" (subject-verb agreement: "kind" is singular, so "This" instead of "These").
• Second sentence: "informed" is incorrect; it should be "implied" (the principal directly stated a suggestion, but "informed" typically refers to giving facts, while the context here is a suggestion, but more critically, the fourth sentence uses "implied" correctly for an indirect suggestion).
• Third sentence: "that is" should be "that are" (subject-verb agreement: "cleansers" is plural, so "are" instead of "is").
• Fourth sentence: No grammatical errors; "implied" correctly conveys the indirect suggestion from the teacher's statement about Manuel being the best student.

Answer:

By saying that Manuel was the best student in class, his biology teacher implied that Manuel would receive an A in the course.
