Select the correct option to substitute the highlighted segment in the given sentence. If no substitution is required, select ‘No substitution’.
He is faster than smarter .

Correct option is A

The correct substitution of the highlighted words is (a) more fast than smart.
Explanation:
The sentence attempts to compare two qualities of the same person — “fast” (physical ability) and “smart” (mental ability). Since they belong to different categories, we cannot directly compare them using comparative adjectives alone like “faster than smarter”.
· Instead, we should use a balanced and grammatically correct comparative structure, such as “more fast than smart”, even though in standard English “faster” is typically preferred over “more fast”.
· However, to maintain parallelism with “smart” (which does not have a comparative form like “smarter” in this structure), "more fast" is acceptable here for stylistic balance.
✔ Corrected sentence: He is more fast than smart.
Grammatical rule used:
When comparing qualities of different types, use "more + adjective" for both to maintain structural symmetry and clarity.
This is especially true when comparing unlike qualities (e.g., physical vs. mental traits).
Example:
She is more kind than wise – Correct.
She is kinder than wise – Incorrect structure.
�� Information Booster:
Use “more + adjective” instead of using a comparative adjective when:
· You are comparing abstract traits.
· The comparison is not between two similar adjectives in comparative form.
