Let's read the text again...
My grandfather the fisherman always told me that the best way to communicate with fish is to drop them a line.
There are three phrases that help us to understand the pun in the text: The grandfather is a fisherman, it means his job is to catch fish, by communicate he means to make the fish come closer, and by drop them a line he means the fishing rod thread.
Taking the above into account the correct answers are:
A.“communicate” and “drop them a line”
B.The pun plays on a phrase that means both to send a note and to attempt to catch a fish.
A dependent clause is a group of words with a subject and a verb, but doesn't make much sense on its own. A lot of times, especially in a sentence with a comma, you can split the sentence and see if it makes any sense.
6. "Before we hiked"
7. "When we go on nature field trips."
8. "Since John was an expert of volcanoes"
9. "If you want to see something closer."
10. "After a volcano erupts"
None of those answers make sense as independent sentences, which is how you can tell they're dependent clauses; they depend on the other part of the sentence.
