Natural disasters can be destructive, they can wreak havoc across large areas and cause loss of life or damage to property. We cannot prevent natural disasters, but we can prepare for them. The first step is to learn about the risks in your area and read the information about natural disasters on local government sites. Next, find out what the rescue and emergency workers advise. These people have been trained to deal with disasters, have been through lots of them and know how to help. Make sure you have all the emergency contact numbers entered in your mobile phone. It is also important that you put together an emergency supply kit. Your emergency supply kit should include food, water Medications, personal hygiene items, copies of personal documents and some money. You may also need some extra clothing if you live in a cold climate. 

2. What is the second step to prepare for natural disasters?

Read the following passage and mark the letter A, B, C or B on your answer sheet to indicate the correct answer to each of the questions from 30 to 37.

   There are a number of natural disasters that can strike across the globe. Two that are frequently linked to one another are earthquakes and tsunamis. Both of them can cause a great amount of devastation when they hit. However, tsunamis are the direct result of earthquakes and cannot happen without them.

      The Earth has three main parts. They are the crust, the mantle, and the core. The crust is the outer layer of the Earth. It is not a single piece of land. Instead, it is comprised of a number of plates. There are a few enormous plates and many smaller ones. These plates essentially rest upon the mantle, which is fluid. As a result, the plates are in constant - yet slow - motion. The plates may move away from or towards other plates. In some cases, they collide violently with the plates adjoining them. The movement of the plates causes tension in the rock. Over a long time, this tension may build up. When it is released, an earthquake happens.

      Tens of thousands of earthquakes happen every year. The vast majority are so small that only scientific instruments can perceive them. Others are powerful enough that people can feel them, yet they cause little harm or damage. More powerful earthquakes, however, can cause buildings, bridges, and other structures to collapse. They may additionally injure and skill thousands of people and might even cause the land to change it appearance.

      Since most of the Earth's surface is water, numerous earthquakes happen beneath the planet's oceans. Underwater earthquakes cause the seafloor to move. This results in the displacement of water in the ocean. When this occurs, a tsunami may form. This is a wave that forms on the surface and moves in all directions from the place where the earthquake happened. A tsunami moves extremely quickly and can travel thousands of kilometres. As it approaches land, the water near the coast gets sucked out to sea. This causes the tsunamis to increase in height. Minutes later, the tsunami arrives. A large tsunami - one more than ten meters in height - can travel far inland. As it does that, it can flood the land, destroy human settlements, and kill large numbers of people.

What is the passage mainly about?

A. How earthquakes and tsunamis occur.

B. What kind of damage natural disasters can cause. 

C. Why tsunamis are deadlier than earthquakes. 

D. When earthquakes are the most likely to happen.
