Correct answer: A
Concept
A sentence is grammatically well formed only when several independent requirements hold at the same time: a determiner agrees in number with the noun it introduces, a finite verb agrees in number with its subject, the head of a noun phrase is a noun rather than a bare verb, a singular countable noun phrase carries a determiner such as “a” or “the”, and every verb or noun takes the particular preposition it selects.
Academic register adds one further requirement. A conclusion reports a settled result, so the simple present is preferred to the progressive, and a noun used in its uncountable sense stays singular.
Application
Test “These findings contribute to a deeper understanding of the topic.” against each requirement in turn:
Determiner–noun number: the plural determiner “These” introduces the plural noun “findings”, so the two agree in number.
Subject–verb agreement: the plural subject “These findings” takes the plural finite form “contribute”, not the singular “contributes”.
Noun-phrase head: after the comparative adjective “deeper” the head must be the noun “understanding”, not the verb “understand”.
Determiner on a singular countable noun: “understanding” is used here in its countable sense — one particular understanding of the topic — and therefore takes “a”; the uncountable reading “deeper understanding” without an article is also possible, so the decisive test in this phrase is the singular countable noun “topic”, which must carry “the”.
Preposition selection: “contribute” selects “to” and “understanding” selects “of”, which yields “contribute to a deeper understanding of the topic”.
Register: the simple present presents the contribution as an established result, which is exactly what a conclusion does.
Cross-check
Each of the other candidate sentences breaks at least one of the same requirements:
Candidate sentence | Requirement it breaks |
|---|---|
These finding contribute to deeper understand of topic. | Plural “These” with singular “finding”; the bare verb “understand” standing in the noun-phrase head slot where the noun “understanding” is required; and “of topic”, which leaves the singular countable noun “topic” without a determiner. |
Findings are contributing for deeper understanding topic. | The preposition after “contributing” is “for”, whereas “contribute” selects “to”; “understanding topic” has no “of” linking the two nouns; and the progressive “are contributing” is less apt than the simple present for a settled conclusion. |
This findings contributes to more understandings. | Singular “This” with plural “findings”; singular “contributes” with a plural subject; and “understandings”, a plural that does not carry the intended sense of knowledge of the topic. |
Every requirement is satisfied by “These findings contribute to a deeper understanding of the topic.”, which is therefore the grammatical and register-appropriate sentence for a research paper conclusion.
