Question

highlight the subordinating conjunction (\swabi\) in the sentence.
spongebob squarepants caught up on old issues of the new yorker while he waited at the airport.

Explanation:

To identify the subordinating conjunction (SWABI) in the sentence, we recall that subordinating conjunctions introduce subordinate clauses and connect them to independent clauses. In the sentence "SpongeBob SquarePants caught up on old issues of The New Yorker while he waited at the airport," the word "while" functions as a subordinating conjunction as it introduces the subordinate clause "he waited at the airport" and connects it to the independent clause "SpongeBob SquarePants caught up on old issues of The New Yorker".
