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 from 31 to 35.
Many people enjoy spending their holidays hiking or climbing in the mountains. Their reasons vary. Some like being outdoors because it is relaxing; others enjoy the positive effects of exercise and fresh air on their mental and physical well-being. Some people even choose the challenge of climbing a mountain summit for the feeling of achievement at the end. Whatever your motivation, it is important to plan and prepare carefully and spend some time before the trip doing physical training, particularly when you are planning to go on long hikes at high altitudes.
Mountain trips can bring health challenges such as altitude sickness. This can be mild, where you might simply develop a headache, but in some cases people need medical attention. It is also important to take into account sudden changes in weather conditions, which can be very unpredictable. If the temperature drops below 0°C, you will easily get frostbite. It is advisable to use cream on your hands and face before your trip, and make sure you wear warm gloves and socks.
Hikers and climbers may also feel unwell because of dehydration, so drinking plenty of water before and during your trip is one of the most important things to remember. Spending a day hiking or climbing may be more demanding on your body than you think. You ought to rest well after each trip to help your muscles recover for the following day.
