“Donate” means to give to someone else, usually to someone who has less than you.

"Generate" is a verb that means "cause something to arise or come about," or "produce," especially when it refers to electricity. While "generous" might look like a potentially correct answer because both "generate" and "gentle" begin with the syllable "gen-," "generous" is an adjective meaning "mild in temperament or behavior; kind or tender" when referring to a person, or "moderate in action, effect, or degree; not harsh or severe." So, since "gentle" and "generate" are not synonyms, "gentle" cannot be the correct answer. Since "create" is the answer choice closest in meaning to "generate," "create" is the correct answer.

"Donate” means to give something to someone for free, usually someone who needs that thing more than you do, so "give" is the correct answer. While "sell" may look like a potentially correct answer, you receive money for a thing when you sell it, whereas you do not receive any money when you donate something.
