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.
