Task V. Fill in the question tag:
- 1. Camels live in the desert, don't they? (The statement is positive, so the tag is negative; 'Camels' is plural, so 'they'.)
- 2. Sarah didn't collect the cans and newspapers, did she? (The statement is negative, so the tag is positive; 'Sarah' is singular.)
- 3. Sarah has called her mum, hasn't she? (The statement is positive, so the tag is negative; 'Sarah' is singular.)
- 4. Gorillas are amazing animals, aren't they? (The statement is positive, so the tag is negative; 'Gorillas' is plural, so 'they'.)
- 5. It can't be true, can it? (The statement is negative, so the tag is positive; 'It' is singular.)
Explanation: Question tags are short questions added to the end of a statement. The tag uses the auxiliary verb from the statement (or 'do/does/did' if there's no auxiliary) and the pronoun representing the subject. If the statement is positive, the tag is negative, and vice versa.
