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 35 to 44.

Bird migration is one of the most interesting yet least understood natural phenomena. Every fall birds from northern latitudes fly in groups to the warmer southern latitudes and then return north in the spring. Scientists agree on the main reasons for migration: to follow the food supply and to avoid harsh climate conditions. For example, insects disappear during the cold months, prompting insect-dependent birds to fly south to warm areas where insects breed. No similar consensus has emerged, however, about how birds are able to navigate. Despite many recent experiments, bird experts still do not know how birds arrive at the same destinations every year and then find their way back home in the spring.

Some have suggested that birds find their way by following landmarks, such as rivers and mountain ranges. Experiments have confirmed that some species do follow such topographic features. But that method cannot explain how some birds travel at night. Other studies show that some nocturnal birds navigate by the stars. But that explanation cannot explain daytime migration or travel when the skies are cloudy.

The most popular explanation currently is that birds are guided by Earth’s magnetic poles. The mechanism by which that works has not yet been proved. One theory points to the fact that some birds’ contain magnetite, a naturally occurring magnetic compound consisting of iron oxide. Magnetite has been found in many animals, including birds. With magnets embedded in their brains, birds would be able to sense the magnetic fields of the North and South Poles.

A recent experiment with homing pigeons provided some evidence that magnetite does play a crucial role in migration. Homing pigeons are known to have the ability to return to their homes after being taken hundreds of miles away. Researchers found that they could train homing pigeons to recognize changes in a magnetic field. When a surrounding magnetic field was normal, the birds would gather at one end of a cage. But when the field’s polarity was altered, they hopped to the other end, suggesting that they were directing and responding to changes in the magnetic field.

Another theory has been offered to explain this sensitivity to magnetic poles, a theory that draws upon quantum mechanics, which is the study of how particles move inside an atom. It relies on the fact that electrons come in pairs that orbits the nucleus of an atom. The two electrons spin in opposite directions, creating two magnets that neutralize each other. But when molecules split and react with other molecules to form compounds, the electrons pairs may no longer spin in opposite directions. Instead,  they may repel each other, as when two north ends of magnets are pressed together. The electrons struggle to change direction in order to achieve a stable state in which the two electrons again neutralize each other, giving off no magnetic field. 

The word “some” in the passage refers to

A. insects                                          

B. recent experiments

C. bird experts                                           

D. birds

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. 

One of the most urgent environmental problems in the world today is the shortage of clean water. Having clean drinking water is a basic human right. However, acid rain, industrial pollution and garbage have made many sources of water undrinkable. 

Lakes, reservoirs and even entire seas have become vast pools of poison. Lake Baikal in Russia is one of the largest lakes in the world. It contains a rich variety of animals and plants, including 1,300 rare species that do not exist anywhere else in the world. Yet, they are being destroyed by the massive volumes of industrial effluent which pour into the lake every day. Even though laws have been made, the governments do not have the power to enforce them. Most industries simply ignore the regulations. The Mediterranean Sea occupies 1% of the world's water surface, but it is the dumping ground for 50% of all marine pollution. Almost sixteen countries regularly throw industrial wastes a few miles offshore. 

Water is free to everyone. A few years ago people thought that the supply of clean water in the world was limitless. Today, many water supplies have been ruined by pollution and sewage. Clean water is now scarce, and we are at last beginning to respect it. What should we do to save this precious source?

19. What is the main idea of the reading text?

A. People are throwing poisons into bodies of water. 

B. Clean water is becoming scarce due to pollution and sewage.

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 following questions from 1 to 5.

     Most Americans look forward to their vacations. Most American employees receive an annual vacation with pay. It is traditional to use this time off for travel.

    Travelling within the United States is very popular because foreign travel generally takes more time and money. However, those who want to travel outside the USA are free to go almost everywhere. Obtaining a passport is not difficult. Every year about thirteen million people travel abroad. The most popular periods are during the Summer and the two-week retool break on Christmas and New Year holidays. These periods are so the most crowded and the most expensive time to travel, so people who can adjust their schedules sometimes choose to travel in the autumn.

    American tourists often travel by car. Most families own a car, and those who do not have a car can rent one. Cars are usually the most economical way to travel, especially for families. It is also fairly fast and convenient. Excellent highways with motels and restaurants nearby connect the nation's major cities. They enable tourists to travel at a speed of 55 to 66 miles an hour. Tourists that want to travel faster often fly to their destination and then rent a car when they get there.

Câu 1: According to the writer, most American employees traditionally use their annual vacations for

     A. jogging                       B. shopping                    C. travelling                  D. cycling

Câu 2: In the USA, to obtain a passport is ______.                           

     A. easy                             B. difficult                     C. expensive                 D. time consuming

Câu 3: There are many American people travelling ______.

     A. in the autumn                                                     B. on Thanksgiving

Đáp án B.

Key words: main idea of the passage.

Trong đoạn 1, 2 tác giả nêu ra rằng âm nhạc Mĩ khởi nguồn từ những người Mĩ gốc Phi; nhưng không ai bận tâm ghi chép về những người đã mang âm nhạc từ quê hương họ tới Mĩ.

Đoạn cuối nói rằng người ta thật khó biết tên của những người đã khơi nguồn cho truyền thống âm nhạc này ở Mĩ. Do đó, đáp án đúng phải là B. it is hard to exactly recognize the people who started the American musical tradition: Thật khó để xác định chính xác những người khởi đầu cho truyền thống âm nhạc ở Mĩ.
