Personally, i would use the term “oblivious” or “ignorant” for more synonyms go to thesaurus.com :)
D is the answer I took the test
"..arrived in the Bay de Todos los Santos, or All Saints’ Bay, in about twenty-two days after."
I think the bolded words would be "whom Mr. Stein chose". The clause whom Mr. Stein chose is an example of an adjective because the clause describes the word student. Student is the subject of the sentence and is a noun. An adjective describes a noun or another subject. an adverb describes a verb or another adverb.
Students would be the subject because they are the ones doing the action. Questions is the direct object, and Elsa is the indirect object
