Question

complete the sentence with the pronoun that agrees with the word or words in bold. philosopher john dalton is credited with developing our modern theory about atoms. dalton proposed that \boxed{} make up elements and combine to form chemical compounds. submit

Explanation:

The bolded word is "atoms", which is a plural noun. The pronoun that agrees with a plural noun (subject of the clause "____ make up elements...") should be a plural subject pronoun. "They" is the appropriate plural pronoun to refer to "atoms" (since atoms are the things that make up elements and combine to form compounds).

Answer:

they
