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

Successful students often do the followings while studying. First, they have an overview before reading. Next, they look for important information and pay greater attention to it (which often needs jumping forward or backward to process information). They also relate important points to one another. Also, they activate and use their prior knowledge. When they realize that their understanding is not good, they do not wait to change strategies. Last, they can monitor understanding and take action to correct or “fix up” mistakes in comprehension.

Conversely, students with low academic achievement often demonstrate ineffective study skills. They tend to assume a passive role, in learning and rely on others (e.g., teachers, parents) to monitor their studying, for example, low-achieving students often do not monitor their understanding of content; they may not be aware of the purpose of studying; and they show little evidence of looking back, or employing “fix-up” strategies to fix understanding problems. Students who struggle with learning new information seem to be unaware that they must extent effort beyond simply reading the content to understand and remember it. Children with learning disabilities do not plan and judge the quality of their studying. Their studying may be disorganized. Students with learning problems face challenges with personal organization as well. They often have difficulty keeping track of materials and assignments, following directions, and completing work on time. Unlike good studiers who employ a variety of study skills in a flexible yet purposeful manner, low-achieving students use a restricted range of study skills. They cannot explain why good study strategies are important for learning; and they tend to use the same, often ineffective study approach for all learning tasks, ignoring task content, structure or difficulty.

Experimental work is being done to make synthetic fuels from coal, or coal tars. But to date, that process has proved expensive. Some experts are trying to revive hydroelectric power which is derived from streams and rivers. Fifty years ago, hydroelectric power provided one third of the electricity used in the United States, but today it supplies only four percent. The oceans are another source of energy. Scientists are studying ways to change the energy of ocean currents, tides, and waves into electricity.

Read the passage carefully then choose the correct answer

Education is not an end, but a mean to an end. In other words, we do not educate children only for the purpose of education them; our purpose is to fit them for life. So it is very important to choose a suitable system of education which will really prepare children for life.

When we say that all of us must be educated to fit us for life, it means that we must be educated in such a way that, firstly, each of us can do whatever job is suited to his brain and ability, and, secondly, that we can realize that all jobs are necessary to society, and that it is very bad to be ashamed of one’s work, or to scorn someone else’s. Only such a type of education can be called valuable to society.
