9. 3. Yes! The correct answer is C. We use 'can' or 'could' when we ask someone to do something (request). Another example: 'Would you do me a favor?'

11. 5. Yes! The correct answer is B. We use 'may' or 'might' (be) when we don't know for sure. Here we are looking for Scott. Nobody knows for sure where he is, but we offer some suggestions. In other words, perhaps he is in the office.

12. 6. Yes! The correct answer is A. We use 'could' instead of 'may' or 'might' because the possibility is smaller here. Another example: I can't find George anywhere. He could be playing tennis.'

13. 7. Yes! The correct answer is B. For the past we use 'must have' (done) and 'can't have' (done) Another example: 'The phone rang, but I didn't hear it. I must have been asleep'.

14. 8. Yes! The correct answer is B. We use 'could' to talk about possible future hapennings. In other words, here it is possible that there will be an increase in the price of gas. Another example: 'Why doesn't Ingrid apply for the job? She could get it.'

15. 9. Yes! The correct answer is C. We often use 'should' when we ask for or give an opinion about something. Often we use 'I think', 'I don't think', 'do you think?'. Another example: 'I don't think you should work so hard.'

16. 10. Yes! The correct answer is A. The modal 'must' has similar meanings to 'should' and 'ought', but is stronger or more definite. Here it is likely that the person will follow the doctor's order. Teacher Marcos
