Choose the sentence that demonstrates correct subject-verb agreement.
Answer and explanation
Correct answer: D. Each of the experimental trials yields consistent and measurable data.
- Step 1: The subject of the sentence is the indefinite pronoun 'Each', which is singular.
- Step 2: Therefore, it takes the singular verb 'yields', irrespective of the intervening plural prepositional phrase 'of the experimental trials'.
Answer
Each of the experimental trials yields consistent and measurable data.
Why not the others: 'A collection... were discovered' errs because the singular collective noun 'collection' requires 'was discovered'; 'Neither... nor the engineers was' errs because the verb must agree with the nearer subject ('engineers', requiring 'were'); 'The rhythm... soothe' errs because singular 'rhythm' requires 'soothes'.
