Question

Which conjunction can fill in the following sentence? He had a severe tooth pain ______________ he visited a doctor.

• A. In
• B. Lest
• C. So
• D. Because

Hint:

When you show a cause-effect relationship, use "so" as the conjunction.

Answer 1

The Correct Option is C

The correct conjunction to use here is "so." The sentence implies cause and effect, where the pain led the person to visit a doctor. "So" connects these two ideas logically. The conjunction "so" introduces a result or consequence, which fits the context of this sentence.
Thus, the correct answer is (c) So.
