1.) both A and D are technically phrases that modify the subject since both use the pronoun "his" which is referring to "Jerome"(subject). I think the more likely to be
D since the phrase is more obvious because it's a prepositional phrase instead of a gerund.
2.) the answer is C because it contsins a subject(show), a verb(let), but begins with a suboordinatin conjunction (after) which means the clause needs an independent clause in order to support it. The rest of the of the
options are phrases, and C could easily be mistaken as a phase considering it starts with "after" which is a preposition. However, because the remark contains a subject and a verb, the word "after" becomes a suboordinating conjunction instead of a preposition.
3.) D is correct because it contains a single independent clause (it was time to get out the sweaters) along with at least one dependent clause (When the birds flew south for the winter).
4.) C is correct because it contains a single independent clause (Andrea could not open the mailbox) along with at least one dependent clause (Since she forgot the key to the lock).
yey
