It can be used to talk about the past, the present or the future. Moreover, It is used to make polite requests. We can also use \"can\" for these, but \"could\" is more polite. For example: \"Could you help me, please?\" It is also used to talk about theoretical possibility and is similar in meaning to \"might\". For example: \"It could be Sarah\'s bag.\" \"Who could it be?\" In sentence number 4, it is talking about a theoretical possibility or a guess. Between \"can\" and \"could\" , \"could\" is better to use in sentence number 4 because it doesn\'t sound awkward. >> Please explain the answer. 3 - They haven\'t eaten for hours- they ____ be starving. must >> CORRECT!! 4 - I\'m busy this morning, but I ____ see you this afternoon if you like. can >> CORRECT!! 5 - It ____ be the postman; it\'s far too early. mustn\'t >> CORRECT!! 6 - You ____ enter the country without a visa.can >> CORRECT!!7 - They\'re two hours late- there ___ be something wrong. must >> CORRECT!! 8 - She left two hours ago, so she ____ have arrived by now. must >> CORRECT!! 9 - My doctor says I ____ lose some weight. must >> CORRECT!! 10 - ____ you smell something burning?
