Select the sentence that properly avoids a double negative:

Answer and explanation

Correct answer: D. The lab technician could not find any evidence of contamination in the sterile culture.

  1. Step 1: A double negative occurs when two negative words are used in the same clause, which cancels the negation or violates standard grammar rules.
  2. Step 2: 'Could not find any' properly pairs the negative adverb 'not' with the non-negative quantifier 'any'.
  3. Step 3: This expresses the intended negative meaning clearly and grammatically.
Answer
The lab technician could not find any evidence of contamination in the sterile culture.
Why not the others: 'could not find no' pairs two negatives; 'couldn't hardly' combines 'not' with the negative adverb 'hardly'; 'scarcely find no' pairs 'scarcely' with 'no'.
