Question

Choose the most suitable option to replace the highlighted part of the sentence:

I am confident to pass the examination.

• A. in passing the exam
• B. to passing the exam
• C. of passing the examination
• D. for passing examination

Answer 1

Answer:

C. of passing the examination

• The Rule of Adjective Collocation: In English, certain adjectives are followed by specific prepositions. The adjective confident typically takes the preposition "of" (or sometimes "about"), not the infinitive "to".

• Gerund Requirement: Prepositions are always followed by a noun or a gerund (an -ing verb acting as a noun). Therefore, "of" must be followed by "passing".

• Putting it together:

  • Incorrect: confident to pass ❌

  • Correct: confident of passing

• Sentence Context: "I am confident of passing the examination." matches the exact formal phrasing and structure of the original sentence while correcting the grammatical error.
