Answer:
1 and 2 are the dependent clauses
Explanation:
If someone wrote you a letter that just had "Mrs. Basel, Mrs. Bates, and Mrs. Wonders" on it, you'd be pretty confused at what message they were trying to convey, same with "Are pretty legit teachers." However, if you received a letter with just "I love ELA!" or "Reading makes me happy" on it, you'd understand the message just fine. 3 and 4 can be spoken normally on their own; however, 1 and 2 need another clause to make sense.
I don’t think i understand
This could be D. I’m not sure.
A simile is first defined as a type of speech that uses one thing or
phrase with comparisons to things of an unrelated kind, often in order
to make a more vivacious description. So of the phrases above, only the
last one (I swear she cast a shadow white as stone) would be considered a
simile, as a shadow white as stone takes two unrelated things and uses
them in an interesting way.
