ATI TEAS (Test of Essential Academic Skills) Version 7English and Language UsageMedium

A medical student is writing a research paper and includes the sentence: 'The data suggests that further investigation is warranted.' A peer reviewer points out a grammatical error. What is the most likely error?

  1. ASubject-verb agreement error with 'data'.
  2. BMisuse of the word 'warranted'.
  3. CIncorrect verb tense for 'suggests'.
  4. DMissing comma after 'suggests'.
Show answer & explanation

Correct answer: A. Subject-verb agreement error with 'data'.

The word 'data' is a Latin plural noun (singular 'datum'). Therefore, it typically takes a plural verb. The sentence should ideally read, 'The data suggest that further investigation is warranted.'

Why the other options are wrong

  • B. 'Warranted' (justified or necessary) is used correctly in this context.
  • C. The verb tense 'suggests' (present tense) is appropriate for a scientific observation, assuming the data still suggests this.
  • D. A comma is not typically required after 'suggests' in this sentence structure.

Subject-Verb Agreement (Data)

Ensuring the verb in a sentence correctly matches its subject in number (singular or plural). For 'data,' historically plural, modern usage often accepts it as singular in some contexts, but academically, plural is preferred.

  • 'Data' is technically the plural of 'datum'.
  • In formal and academic writing, 'data' typically takes a plural verb (e.g., 'data are').
  • In informal or common usage, 'data' is sometimes treated as a singular mass noun (e.g., 'data is').

Memory trick: Subject and verb should always agree, like partners in a dance.
