Directions: Select the suitable conjunction to complete the sentence: The pain…

Solution: The correct word is "so".

"So" is a coordinating conjunction meaning "therefore" or "as a result." It links the first independent clause (the cause) with the second clause (the result).

Because both parts are independent clauses, place a comma before "so" when joining them.

• "because" — Incorrect: indicates a reason and would imply the specialist caused the pain, which does not match the intended meaning.

• "yet" — Incorrect: shows contrast or something unexpected, not a causal result.

• "but" — Incorrect: introduces contrast rather than indicating a result.

• "so" — Correct: properly shows that the action of going to see a specialist is the result of the pain being unbearable.

Correct sentence: The pain was unbearable, so I went to see a specialist.
