Which practice should be considered when teaching learners to answer multiple-choice items?

Selecting answers that are grammatically correct is essential when teaching learners to answer multiple-choice items, as it enhances comprehension and clarity in questions and answer choices. Grammatically correct options tend to adhere to standard language rules, which helps students understand what is being asked without being distracted or confused by awkward phrasing or incorrect grammar. This is particularly important in a testing scenario where clarity is crucial to ensure that students can focus on content knowledge rather than deciphering poorly constructed language.

In contrast, vague information can obscure the meaning of answers, making it harder for students to determine the correct choice. Ignoring key terms such as "not" and "except" can lead to misunderstandings of what the question is asking, potentially resulting in incorrect answers. Additionally, rushing through the options without careful consideration may cause students to overlook critical details or nuances in the answer choices that could help guide them to the right selection.
