Select the option that will improve the (bracketed) part of the sentence. In case of no improvement select the option 'No improvement'.
Check all radiators for (meagre leaks, special) round pipework connections.

Correct option is D

The correct substitution of the highlighted part is (d) small leaks, especially.
Explanation:
· “Meagre” means insufficient or lacking in quantity, not suitable for describing “leaks.”
· “Special” is incorrect as an adverb. The correct form here is “especially”, which modifies the verb “check.”
Grammatical rule used:
Use adjectives to describe nouns and adverbs to modify verbs or adjectives.
“Especially” is the correct adverb to show specific focus.
Example: Check all outlets, especially near the stove.
