Fill in the blank with most appropriate option:
This book is ___ than the one I read last week.
Show answer & explanation
Correct answer: C
Explanation
Correct Answer
more interesting
Explanation
The sentence requires the correct degree of the adjective to fill in the blank.
The presence of the word "than" indicates that a direct comparison is being made between two distinct items: "this book" and "the one I read last week." This structure requires the comparative degree.
The word interesting is a long, multi-syllable adjective (containing four syllables). Unlike short adjectives that take the suffix "-er", multi-syllable adjectives must form their comparative degree by placing the word "more" before them. Therefore, more interesting is the grammatically correct choice.
The other choices are incorrect for the following reasons:
Interesting is the positive degree, used when describing a single noun without any comparison.
Interest is either a noun or a verb, not an adjective that fits this modifier slot.
Most interesting is the superlative degree, which is strictly used when comparing three or more things.
Key Points
For multi-syllable adjectives (e.g., beautiful, difficult, interesting), the formula for comparison is always more + adjective + than.
