Choose the option that best best completes the gap(s).
Your performance will improve if you _____ hard.
Answer Details
The correct option is "practise" (or "practice" in American English). The sentence is in the conditional form, which means that it talks about a hypothetical situation or a possibility. The verb tense "would practice" suggests a hypothetical situation, which is not suitable for the context of the sentence. The option "practical" is an adjective, which does not fit the structure of the sentence. "Are practising" is in the present continuous tense, which also suggests a continuous or ongoing action, but the sentence talks about a general improvement. Therefore, the correct answer is "practise," which is the simple present tense and indicates a general action.
