Rewrite each sentence so it means exactly the same: with a key word, a stronger word or a different structure. It is the skill behind good B2 writing, and the key word task in Cambridge exams.
Key word

Complete the second sentence so it means the same. Use the key word.
Key wordlastDon’t change it. 2 to 5 words in the gap.
