Q1  15
Q1 15

Question 1: If you ___ sugar into hot water, it dissolves.

Question 1 options
'put' is correct because the zero conditional requires the present simple tense in the if-clause. 'will put' uses a future form, 'are putting' uses the present continuous, and 'put' is the only present simple option that fits this general truth.
Q2 15

Question 2: If you touch fire, it ___ you.

Question 2 options
'burns' is correct because the zero conditional uses the present simple tense in the main clause to express a general truth. 'will burn' belongs to the first conditional, 'burned' is past simple, and 'is burning' is present continuous — none of these are used in the zero conditional.
Q3 15

Question 3: In zero conditional sentences, both the if-clause and the main clause use the present simple tense.

Question 3 options
True because the zero conditional structure is: if/when + present simple, present simple. Both clauses must use the present simple to express general truths or facts that always happen.
Q4 15

Question 4: Which situation is best described using the zero conditional?

Question 4 options
'A scientific fact that is always true' is correct because the zero conditional expresses general truths, natural laws, and situations that always happen under certain conditions. It is not used for future plans, past habits, or imaginary situations.
Q5 15

Question 5: Arrange the words to make a correct sentence:

Question 5 options
  • freeze water,
  • If you
  • it becomes
  • ice.

Drag items or use arrows to arrange them in the correct order.

The correct order is: 'If you freeze water, it becomes ice.' This is a zero conditional sentence using if + present simple, present simple to state a general scientific truth.
Q6 15

Question 6: Which sentence is grammatically correct?

Question 6 options
'If plants don't get water, they die.' is correct because both clauses use the present simple tense, which is required by the zero conditional. The other options incorrectly use 'will', 'are getting', or 'died' in one of the clauses.
Q7 15

Question 7: Teacher: 'How do you explain that the road gets slippery in winter?' Student: 'Well, ___ it snows, the road gets slippery.'

Question 7 options
'when' is correct because in the zero conditional, 'when' can replace 'if' to express something that always happens under a certain condition. 'although', 'unless', and 'because' change the meaning and do not form a standard zero conditional.
Q8 15

Question 8: Which sentence correctly uses the zero conditional (not the first conditional)?

Question 8 options
'If you mix yellow and blue, you get green.' is correct because it uses present simple in both clauses to state a general truth. The first conditional uses 'will + base verb' in the main clause for future possibilities, not present simple.
Q9 15

Question 9: Put the words in the correct order:

Question 9 options
  • if it rains.
  • The ground
  • gets wet

Drag items or use arrows to arrange them in the correct order.

The correct order is: 'The ground gets wet if it rains.' When the if-clause comes second, no comma is needed. Both clauses use the present simple tense as required by the zero conditional.
Q10 15

Question 10: If you ___ too much coffee, you feel nervous and cannot sleep well.

Question 10 options
'drink' is correct because the zero conditional requires the present simple in the if-clause to express a general truth about what always happens. 'are drinking' is present continuous, 'drank' is past simple, and 'will drink' is a future form — none belong in the zero conditional.
Q11 15

Question 11: Which statement about the zero conditional is true?

Question 11 options
'It expresses situations that are always true or always happen' is correct. The zero conditional describes general facts and natural laws. It does not talk about unlikely events (that's the third conditional) or specific future plans (that's the first conditional), and it does not require 'will' in either clause.
Q12 15

Question 12: Original: 'If people eat too much, they get fat.' Rewrite using 'when': When people eat too much, ___.

Question 12 options
'they get fat' is correct because 'when' can replace 'if' in the zero conditional without changing the meaning. The main clause must remain in the present simple. 'they will get fat' adds 'will', which belongs to the first conditional, not the zero conditional.
Q13 15

Question 13: Match each sentence to the correct grammar label.

Question 13 options
If you heat metal, it expands.
When you mix black and white, you get grey.
Ice melts if the temperature rises above 0°C.
Unless you water plants, they die.
Zero conditional: 'when' replacing 'if'
Zero conditional: general scientific truth
Zero conditional: 'unless' meaning 'if not'
Zero conditional: if-clause in second position, no comma

Select an item on the left, then tap its match on the right.

The zero conditional uses present simple in both clauses for general truths. 'When' can replace 'if'. The if-clause can come first (with comma) or second (no comma). 'Unless' means 'if not' in zero conditional sentences.
Q14 15

Question 14: In zero conditional sentences, the if-clause must always come before the main clause.

Question 14 options
False because the order of clauses in the zero conditional is flexible. The if-clause can come first (with a comma) or second (without a comma). For example, both 'If it rains, the ground gets wet' and 'The ground gets wet if it rains' are correct.
Q15 15

Question 15: Which sentence best expresses a general rule or instruction using the zero conditional?

Question 15 options
'If the mixture turns red, add more water.' is correct because it uses an imperative in the main clause to give an instruction based on a consistent condition, which is a valid use of the zero conditional. The other options use 'will', past simple, or present continuous, which do not match the zero conditional structure.
