17. c. I was running. (because it indicates the interrupted scene (stepped on the broken glasses) in the activity in progress in the past )
18. d. I'm afraid you can't. (since that is the only refusal answer in the options available)
19. b. I will have lived (the sentence indicates the usage of future perfect tense as there's a phrase ' by the time....')
20. b. to look after (the only possible answer although it's a bit too much for a receptionist. The proper term would be ' to deal with the visitors' inquiries and complaints' )
