Which sentence correctly avoids the double comparative error?

Explanation

Multi-syllable adjectives such as ‘intelligent’ form their comparative degree by placing ‘more’ before the adjective, rather than adding an ‘-er’ ending directly to the word. Combining both methods at once, as in ‘more intelligenter,’ creates what is called a double comparative, which is grammatically incorrect. This error is a frequently tested trap in comparative and superlative degree questions. Explore more English MCQs on mcqstutor to keep practicing.
