In which part of the test would candidates demonstrate their understanding of sentence structure?

Demonstrating understanding of sentence structure primarily takes place in the grammar section of the test. This section is specifically designed to assess candidates' knowledge of the rules that govern how sentences are formed, including aspects such as subject-verb agreement, the proper use of clauses, and the correct arrangement of words to convey clear and effective meaning.

In the grammar section, candidates engage with various exercises that require them to identify correct or incorrect sentence constructions, rewrite sentences for clarity or conciseness, and select appropriate grammatical forms. This focused approach allows them to showcase their grasp of sentence structure in a comprehensive manner.

While other sections, such as the writing section, may also touch upon sentence structure indirectly, they often prioritize overall composition and coherence rather than dissecting the individual components of sentences. Consequently, the grammar section is the most direct and relevant part of the test for assessing understanding of sentence structure.
