Explanation:
An analogy is comparing two things so you are looking for a relationship.
In 2, the relationship is the manner in which you put the first thing around the second thing. As you would wrap a present, so would you swaddle a baby.
In 3, the relationship is synonyms.
In 4, the relationship is the purpose of the first thing. The purpose of a swimming pool is recreation, the purpose of a moat is protection.
In 5, the relationship is similar things. An ocean is a body of water, so is a sea. Embarrassment and humiliation are synonyms.
In 6, the relationship is again similar things. Garbage and debris are synonyms, as are plaything and toy.
In 7, the relationship is opposites. Praise and ridicule are antonyms and so are build and destroy
In 8, the relationship is again opposites. Temporary and permanent are antonyms and so are common and unusual.
