A、You can find that it is hot during the night. B、You may travel across few rough roads. C、You can not find shade in the desert

M: So, Kate.in your book Lesser Known Egypt you recommend(19)all sorts of exciting and interesting places away from the popular tourist tracks.
W: Yes, and for the really brave tourist none of them is at all difficult to get to.
M: Right.
W: All you need is a little bit of planning in advance and even that’s easy if you use my book.
M: You suggest people should go in the winter when the heat is not so overwhelming, don’t you?
W: Exactly, and it can even get quite chilly at night, so you might need something to keep you warm. Remember, in the daytime you’ll find it’s almost always sunny.(20)You have to do quite a lot of walking over rough ground in the desert, and of course there’s no shade, so I never went out without something to cover my head or I’d have got quite sun burnt. I’d strongly advise other people to do the same.
M: (21)And what was the most enjoyable thing you found about travelling around Egypt on your own?
W: (21)Without a doubt the people I travelled with. It could all have been quite unpleasant otherwise, you know, waiting for buses in dusty villages and so on, but I found everyone so kind. You know, they’d make conversation, invite me to coffee and really help me to get to know the country. Otherwise I wouldn’t have enjoyed things nearly so much. As it was, I felt that I wanted the journey to go on forever.
M: Fantastic.
W: Yes, indeed.
