Passage 2. Read the following passage about endangered languages and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questionsfrom 1 to 5.

An engine is a machine that creates mechanical motion from energy. In order to do this, an engine frequently requires some type of fuel to burn. Nowadays, many engines are used to power cars and other forms of transportation. These vehicles most commonly have an internal combustion engine and rely upon gasoline for power. However, there are several types of engines that can use alternative energy sources. Many people are trying to switch to them because gasoline, which is a fossil fuel, creates pollution and is also a non-renewable resource.

These days, engines that are able to burn biofuels are somewhat common. Biofuels are fuels that are made from biological material, such as corn, soybeans, and sugarcane. These biofuels burn cleanly, so they produce much less pollution than fossil fuels. In some countries, such as Brazil, cars with biofuel engines are standard. In fact, most of the cars in Brazil have engines that can operate on either gasoline or biofuel.

A second type of alternative engine is the electric engine. Cars with electric engines have been common for decades. Most are being used in hybrid cars at the moment. These are vehicles that have both a gasoline-powered engine and an electric one. In many cases, the gasoline-powered engine is used to operate the car at high speeds on expressways. The electric engine is utilised for city driving. One benefit of hybrid cars is that as the gasoline-powered engine runs, it simultaneously recharges the electric engine.

A third type of alternative engine is the hydrogen engine. It utilises hydrogen fuel cells, which convert hydrogen into electricity that can power the car These days, there are many cars and buses that rely upon hydrogen engines. However, there are some problems associated with this type of engine. The hydrogen used in the engine must be processed from other materials, and it is also difficult to store. As a result, vehicles that run on hydrogen are expensive.

Alternative energy sources create less pollution and are often renewable sources of energy. It is hoped that more and more innovations help the use of alternative energy sources become easier and easier.
