Câu 1

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

Supernovas are the most powerful and spectacular outbursts known in nature. What is called a Type II supernova is due to the collapse of a massive star, at least eight times as massive as the sun, that has used up its main nuclear fuel and produced a nickel-iron core. When this core can no longer support the pressure of the star’s outer layer, it collapses to form a neutron star of immense density. Over 2,500 million tons of neutron star packed into a matchbox. Its temperature is around 100,000 million degrees centigrade. Multitudes of neutrons are produced in the collapsed star, which pass directly through the star into space, and this release of neutrons causes the core to respond with a shock wave that moves outward. When it meets the material that is falling inward, the result is a catastrophic explosion. Sometimes most of the star’s material is blown away, leaving only a small, incredibly dense remnant that may be a neutron star or, in extreme cases, a black hole. A supernova is often more than 500 million times as luminous as the sun. A supernova remnant (SNR) may be detectable as a pulsar, an example of which is the Crab Nebula, known to be a remnant of the supernova observed in the year 1054. The 1987 supernova in the Large Cloud of Magellan had a low peak luminosity by supernova standards, only about 250 million times that of the sun. As its brightest the supernova shone as a star between magnitudes 2 and 3, even though it was 170,000 light-years away.

What is the main topic of the passage?

A. The heat of supernovas

B. The formation and power of a supernova

C. The role of shock waves in a supernova

D. The density of a neutron star.

Lời giải

Đáp án B
Giải thích: Dựa vào nội dung của cả bài đọc, ta có B là đáp án đúng nhất nói về Sự hình thành và sức mạnh của sao băng

Câu 2

According to the passage, which of the following is TRUE about the 1987 supernova?

A. It was the brightest supernova.

B. It was brighter than the sun.

C. It shone as a star between magnitudes 3 and 4.

D. It had the lowest peak luminously.

Lời giải

Đáp án B
Giải thích: Dựa vào thông tin của câu "The 1987 supernova in the Large Cloud of Magellan had a low peak luminosity by supernova standards, only about 250 million times that of the sun" ở đoạn thứ hai, ta thấy Sao băng 1987 sáng hơn mặt trời khoảng 250 triệu lần.
