Question

Neither recordings nor photographs can be copied or borrowed because they are so fragile. Which underlined word is the subordinating conjunction? or because Neither nor

Answer 1

because

Answer 2

The answer is "because." Subordination conjunctions introduce adverb clauses. "Neither", "or" and "nor" are incorrect because they are part of the main (independent) clause. "They are so fragile" is a dependent clause because it depends on the first part to make sense. A conjunction connects these two clauses.
