What type of tasks are included in the Use of English section regarding word formation?

The correct answer pertains to tasks that require converting nouns, verbs, adjectives, and adverbs into different forms. This type of exercise is specifically designed to assess a candidate's understanding of word formation processes in the English language, which include the ability to use prefixes, suffixes, or derive forms appropriately based on context.

For example, a task might present a base word, such as "happy," and ask for its noun form "happiness," or its adjective form "unhappy." The focus is on demonstrating knowledge of how words relate to one another and are constructed, which is a fundamental skill in achieving fluency and accuracy in English.

The other options do not accurately reflect the primary goal of the Use of English section. Translating words does not involve the same level of understanding of English word formation. Grammar corrections focus more on sentence structure than on the form of individual words. Likewise, vocabulary enhancement does not specifically address the mechanics of word transformation as described in this context.
