ANSWER KEY & EXPLANATIONS
1 (c) rains
- Why it is correct (The Key): Type 1 Conditional uses the Present Simple in the if-clause for a highly likely future event.
- Error Analysis: Option (a) “will rain” is a Common Mistake (putting future tense in the if-clause). Option (d) “rain” is a Structural Error (wrong subject-verb agreement for “it”). Option (b) “rained” is a Strong Distractor (matches Type 2, but the result clause uses “will move”).
2 (a) will cancel
- Why it is correct (The Key): The main clause in a Type 1 conditional requires “will + base verb” to show the future result of the condition.
- Error Analysis: Option (d) “would cancel” is a Common Mistake (mixing Type 2 result with a Type 1 condition). Option (b) “cancel” is a Structural Error (missing the future auxiliary). Option (c) “cancelled” is a Strong Distractor (past tense doesn’t fit a future prediction).
3 (b) gets
- Why it is correct (The Key): Present Simple in the if-clause. “Wind” is singular.
- Error Analysis: Option (a) “will get” is a Common Mistake. Option (c) “getting” is a Structural Error. Option (d) “got” is a Strong Distractor.
4 (d) postpone
- Why it is correct (The Key): Present Simple after “if”. “We” takes the base verb.
- Error Analysis: Option (b) “will postpone” is a Common Mistake. Option (c) “postpones” is a Structural Error. Option (a) “postponed” is a Strong Distractor.
5 (c) will feel
- Why it is correct (The Key): The result clause requires “will + base verb” for a future outcome.
- Error Analysis: Option (d) “would feel” is a Common Mistake (Type 2 result mixed with Type 1 condition “provide”). Option (a) “feel” is a Structural Error in this specific future context. Option (b) “felt” is a Strong Distractor.
6 (b) passes
- Why it is correct (The Key): “Unless” means “if not”. It requires an affirmative Present Simple verb.
- Error Analysis: Option (c) “doesn’t pass” is a Common Mistake (creates an illogical double negative: “unless it doesn’t pass”). Option (a) “will pass” is a Common Mistake. Option (d) “pass” is a Structural Error.
7 (a) becomes
- Why it is correct (The Key): Present Simple in the if-clause. “Ground” is singular.
- Error Analysis: Option (b) “will become” is a Common Mistake. Option (d) “become” is a Structural Error. Option (c) “became” is a Strong Distractor.
8 (c) will we do
- Why it is correct (The Key): Correct question word order for the future result clause (Question word + Will + Subject + Base Verb).
- Error Analysis: Option (b) “do we do” is a Common Mistake (Type 0 question, lacking the specific future focus). Option (a) “we will do” is a Structural Error (statement word order). Option (d) “would we do” is a Strong Distractor.
9 (d) will turn
- Why it is correct (The Key): The result of the specific generator failure tomorrow is a future action.
- Error Analysis: Option (c) “would turn” is a Common Mistake. Option (a) “turns” is a Strong Distractor (Type 0, but this is a specific future event, not a general manual fact). Option (b) “turned” is a Structural Error.
10 (a) remains
- Why it is correct (The Key): “As long as” acts like “if”. “Rain” is an uncountable singular noun, requiring “remains”.
- Error Analysis: Option (b) “will remain” is a Common Mistake. Option (d) “remaining” is a Structural Error. Option (c) “doesn’t remain” is a Strong Distractor (ruins the logical meaning of the sentence).
11 (b) don’t hire
- Why it is correct (The Key): Negative Present Simple in the if-clause to establish the condition.
- Error Analysis: Option (a) “won’t hire” is a Common Mistake (using future in the if-clause). Option (d) “not hire” is a Structural Error (missing auxiliary “do”). Option (c) “didn’t hire” is a Strong Distractor.
12 (d) gets
- Why it is correct (The Key): Present Simple in the if-clause. “Weather condition” is singular.
- Error Analysis: Option (b) “will get” is a Common Mistake. Option (a) “get” is a Structural Error. Option (c) “got” is a Strong Distractor.
13 (c) approves
- Why it is correct (The Key): Present Simple condition. “City council” acts as a singular entity.
- Error Analysis: Option (b) “will approve” is a Common Mistake. Option (d) “approve” is a Structural Error. Option (a) “approved” is a Strong Distractor.
14 (b) covers
- Why it is correct (The Key): “Provided that” functions like “if”. “Everyone” is a singular pronoun.
- Error Analysis: Option (c) “will cover” is a Common Mistake. Option (a) “cover” is a Structural Error. Option (d) “covered” is a Strong Distractor.
15 (a) makes
- Why it is correct (The Key): Affirmative Present Simple after “Unless”. “Manager” is singular.
- Error Analysis: Option (b) “doesn’t make” is a Common Mistake (double negative logic flaw). Option (c) “will make” is a Common Mistake. Option (d) “make” is a Structural Error.
16 (c) continues
- Why it is correct (The Key): Present simple in the if-clause. “Might” in the result clause is a valid substitute for “will” to show a slightly less certain future possibility.
- Error Analysis: Option (a) “will continue” is a Common Mistake. Option (d) “is continue” is a Structural Error. Option (b) “continued” is a Strong Distractor.
17 (d) refuses
- Why it is correct (The Key): “Supposing” acts like “if”. Present simple “refuses” matches the future “will take”.
- Error Analysis: Option (a) “will refuse” is a Common Mistake. Option (c) “refuse” is a Structural Error. Option (b) “refused” is a Strong Distractor.
18 (b) block
- Why it is correct (The Key): Present simple in the if-clause after the pronoun “they” (umbrellas).
- Error Analysis: Option (a) “will block” is a Common Mistake. Option (d) “blocking” is a Structural Error. Option (c) “blocked” is a Strong Distractor.
19 (a) rises
- Why it is correct (The Key): Present simple for the condition. Notice that the main clause uses a modal verb (“must ensure”) which is completely grammatically valid for Type 1
- Error Analysis: Option (b) “will rise” is a Common Mistake. Option (d) “rise” is a Structural Error. Option (c) “rose” is a Strong Distractor.
20 (c) will initiate
- Why it is correct (The Key): Future simple in the result clause based on an emergency condition.
- Error Analysis: Option (a) “initiate” is a Common Mistake. Option (d) “are initiate” is a Structural Error. Option (b) “initiated” is a Strong Distractor.
GRAMMAR POINTS TO REMEMBER
- Type 1 Conditional Structure: If + Present Simple, Subject + Will (or Can/Must/Might) + Base Verb. It is used to plan for realistic, highly probable future situations, making it the perfect structure for contingency planning (Plan B).
- The “No Future in IF” Rule: The most frequent B1 mistake is putting will or won’t directly inside the condition clause (e.g., If it will rain -> Incorrect). The condition is always in the Present Simple.
- Modals in the Result Clause: You don’t always have to use will. You can use modals like can (ability), must (obligation), or might (possibility) in the main clause depending on the context of the plan.
- Unless Trap: Unless already carries the meaning of “If… not”. Following it with a negative verb (e.g., Unless he doesn’t come) creates a grammatically confusing double negative. Always use an affirmative verb after unless.
- Alternative Connectors: Words like provided that, as long as, and supposing function exactly like if and follow the same Type 1 grammar rules.
