Identify the part of the sentence that contains a grammatical error.
A. The new smartphone is B. much more sleeker C. and lighter than D. the previous model.
Show answer & explanation
Correct answer: B
Explanation
The error is in part B because it uses a double comparative form ("more sleeker"). The adjective "sleek" is a one-syllable word, so its comparative form is made by adding the suffix "-er" (sleeker). It should be "much sleeker".
