I'm not 100% sure, but here is what I think the answers are:
Answer:
Definition matches with "Gives an explanation of the unfamiliar word right in the sentence."
Inference matches with "Provides the general sense of an unfamiliar word with the main idea of a sentence or paragraph."
Antonym matches with "Contrasts the unfamiliar word with an opposite."
Synonym matches with "Restates the unfamiliar word with another familiar word."
Goodluck, sorry if any of these are wrong!
