Q45. The dentist had to the decayed tooth to prevent further infection.

1. A. modify
2. B. excuse
3. C. recruit
4. D. amplify
5. E. remove (Correct answer)

Correct Answer

Option E — remove

Detailed Solution & Explanation

The correct answer is remove.

Key Points

• The sentence needs a verb meaning 'to take out': 'The dentist had to remove the decayed tooth to prevent further infection.'
• 'Remove' fits both the meaning (extracting a decayed tooth) and the context (preventing infection).
• The other options are wrong: 'modify' (change), 'excuse' (forgive), 'recruit' (enlist) and 'amplify' (increase) make no sense with a decayed tooth.
• in fill-in-the-blank vocabulary questions, choose the word whose meaning matches the sentence's logic — here the purpose clause 'to prevent further infection' signals that the tooth must be taken out.

Exam Tip

• read the whole sentence, especially the part after the blank, before choosing; the reason or result clause usually points to the correct verb.
