ANSWER KEY & EXPLANATIONS
1 (A) will
Why it’s correct: “I am sure” shows a prediction based on the speaker’s personal belief, not physical evidence.
Error Analysis: (B) Common Mistake: “Are going to” is used for plans or predictions with present physical evidence. (C) Structural Error: “Will to” is incorrect grammar. (D) Strong Distractor: “Might” implies uncertainty (maybe yes, maybe no), which fails to reassure the worried friend.
2 (C) will
Why it’s correct: “I really think” introduces a subjective opinion about the future.
Error Analysis: (B) Common Mistake: Incorrectly using “going to” for an opinion. (A) Structural Error: “Will doing” uses the wrong verb form. (D) Strong Distractor: “Should” means it’s a good idea, not a confident prediction.
3 (B) will
Why it’s correct: “I believe” signals a personal feeling about a future outcome.
Error Analysis: (A) Common Mistake. (C) Structural Error: “Will being” is grammatically wrong. (D) Strong Distractor: “Ought to” sounds like advice rather than a comforting prediction.

Why it’s correct: “I know” in this context expresses the speaker’s strong personal confidence in their friend.
Error Analysis: (B) Common Mistake. (C) Structural Error: Missing the “to” and the main verb. (D) Strong Distractor: “Can” only talks about ability (“You are able to”), not the certainty of the future event.
5 (C) will
Why it’s correct: “I am certain” introduces a strong subjective prediction.
Error Analysis: (A) Common Mistake. (B) Structural Error: “Will to” is incorrect. (D) Strong Distractor: “Has to” means the teacher is forced to like it, which is illogical.

Why it’s correct: “I think” clearly marks this as a personal prediction.
Error Analysis: (A) Common Mistake. (C) Structural Error: Adding “to” after “will”. (B) Strong Distractor: “Shouldn’t” gives the opposite meaning (they shouldn’t love it!).

9 (B) will
Why it’s correct: Asking for someone’s opinion (“Do you think…”) requires “will”.

GRAMMAR POINTS TO REMEMBER
1 “Will” for Opinions and Beliefs:
When you predict the future based on what you think, feel, or believe in your mind (not based on physical evidence you can see), you must use “will”.
This is the standard grammar tool for reassuring people, encouraging them, or expressing your faith in their abilities.
2 Common Signal Words:
If you see these phrases, it is a massive clue that you should use “will”:
- I think / I don’t think…
- I believe / I expect…
- I am sure / I am certain…
- In my opinion…
3 Why “Going to” is incorrect here:
Many students translate word-for-word and use “going to” to mean “sẽ” in all situations. However, if you say “I think you are going to pass,” it sounds slightly unnatural to a native speaker because “going to” requires solid proof (like seeing the test score), whereas “I think” means you are just guessing based on your feelings. “I think you will pass” is the most authentic, natural English phrasing.
