OOPT Conditional Structures 4 — Questions and Answers
Question 1: Choose the correct mixed conditional: 'If she _____ harder when she was young, she _____ successful now.'
- had studied / would be (Correct answer)
- studied / would have been
- had studied / would have been
- studies / will be
Correct answer: had studied / would be
Mixed conditionals combine a past unreal condition (had studied) with a present result (would be).
Question 2: Which sentence uses the zero conditional correctly?
- If you freeze water, it turns to ice. (Correct answer)
- If you froze water, it would turn to ice.
- If you had frozen water, it would have turned to ice.
- If you will freeze water, it turns to ice.
Correct answer: If you freeze water, it turns to ice.
The zero conditional uses simple present in both clauses to express universal truths.
Question 3: Select the correct inverted conditional form: '_____ any problems arise, please contact support immediately.'
- Should (Correct answer)
- Would
- If would
- Were to should
Correct answer: Should
'Should any problems arise' is a formal inversion of 'If any problems should arise.'
Question 4: What does 'Unless you leave now, you'll miss the train' mean?
- If you don't leave now, you'll miss the train. (Correct answer)
- If you leave now, you'll miss the train.
- You'll miss the train even if you leave now.
- You won't miss the train if you stay.
Correct answer: If you don't leave now, you'll miss the train.
'Unless' means 'if not,' so 'unless you leave' = 'if you don't leave.'
Question 5: Complete the third conditional: 'They _____ the game if their best player _____ injured.'
- would have won / hadn't been (Correct answer)
- would win / wasn't
- will win / isn't
- would have won / wasn't
Correct answer: would have won / hadn't been
Third conditionals use 'would have + past participle' and 'hadn't + past participle' for past unreal situations.
Question 6: Which sentence expresses a wish about the present using a conditional structure?
- I wish I knew the answer. (Correct answer)
- I wish I had known the answer.
- I wish I will know the answer.
- I wish I know the answer.
Correct answer: I wish I knew the answer.
'I wish I knew' uses past simple to express an unreal present wish, mirroring second conditional structure.
Question 7: Identify the error: 'If I would have more time, I would exercise every day.'
- 'would have' should be 'had' (Correct answer)
- 'would exercise' should be 'will exercise'
- 'every day' should be 'everyday'
- There is no error.
Correct answer: 'would have' should be 'had'
In second conditionals, the if-clause uses past simple ('had'), not 'would have.'
