Find the part of the sentence that contains an error:

The initiatives praised by the committee (1)/ are not only designed to modernise reporting systems (2)/ but also improving transparency in funding distribution (3)/ across all districts. (4)

The correct option containing the error is (3).

Detailed Explanation:

This question tests the rule of parallel construction (parallelism) when using correlative conjunctions such as "not only ... but also".

In English grammar, the grammatical structures following "not only" and "but also" must match in form.

Let's analyze the sentence structure:

• After "not only", we have the infinitive verb form: designed to modernise reporting systems (specifically, the infinitive verb "to modernise").

• After "but also", part (3) uses the present participle form: improving transparency in funding distribution.

Because part (2) uses the base infinitive verb structure following "to" (to modernise), part (3) should maintain parallelism by using the corresponding base infinitive verb form (to improve or simply improve, since "to" is carried over).

Correction:

Change "but also improving transparency" in part (3) to "but also to improve transparency" (or "but also improve transparency").

Corrected Sentence:

"The initiatives praised by the committee are not only designed to modernise reporting systems but also to improve transparency in funding distribution across all districts."
