Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

The first thing to do when you have a trip abroad is to check that your passport is valid. Holders of out-of-date passports are not allowed to travel overseas. Then you can prepare for your trip. If you don't know the language, you can have all kinds of problems communicating with local people. Buying a pocket dictionary can make a difference. You'll be able to order food, buy things in shops and ask for directions. It's worth getting one. Also there's nothing worse than arriving at your destination to find there are no hotels available. The obvious way to avoid this is to book in advance. This can save you money too. Another frustrating thing that can happen is to go somewhere and not know about important sightseeing places. Get a guide book before you leave and make the most of your trip. It's a must.

Then, when you are ready to pack your clothes, make sure they are the right kind. It's no good packing sweaters and coats for a hot country or T-shirts and shorts for a cold one. Check the local climate before you leave.

Also, be careful how much you pack in your bags. It's easy to take too many clothes and then not have enough space for souvenirs. But make sure you pack essentials, what about money? Well, it's a good idea to take some local currency with you but not too much. There are conveniently located cash machines (ATMs) in most big cities, and it's usually cheaper to use them than change your cash in banks. Then you'll have more money to spend. When you are at your destination, other travellers often have great information they are happy to share. Find out what they have to say. It could enhance your travelling experience.
