Identify the part of the sentence that contains a grammatical error.
The paradigm of rational choice theory (1) postulate that agents act consistently (2) to maximize utility, often ignoring (3) the constraints imposed by affective reasoning. (4)
Show answer & explanation
Correct answer: B
Explanation
Correct Answer: (2)
Explanation:
• The error lies in part (2) due to a subject-verb agreement issue.
• The head noun of the subject phrase is 'The paradigm', which is singular. The prepositional phrase 'of rational choice theory' merely describes it.
• A singular subject takes a singular verb in the present tense. Therefore, 'postulate' must be replaced with 'postulates'.
Correct Sentence: The paradigm of rational choice theory postulates that agents act consistently to maximize utility, often ignoring the constraints imposed by affective reasoning.
