Read the following article and select the best answer. Article: The young policeman, Constable Rider, walked more quickly than usual, because of the cold, but he did not consciously neglect any part of his work. His torch flashed on doorways and windows as he looked for anything that was at all suspicious, and when he ever thought that anything was unusual, he went to try the door and window, probably unheard by the people sleeping in the room just above his head. As he turned a corner, he heard a slight rustling sound -- it might be a cat, it could even be a dog, although few dogs wandered about at night. Rider saw nothing. A cat then? Usually if you disturbed a cat, it ran off and jumped, and you heard or noticed something else. By doing a lot of night, you learned to notice these things, but now all Rider noticed was the silence which had followed the rustling sound. So he acted cautiously. He did not flash his torch about the houses near the corner but walked on, and, a little way from the spot where he heard the sound, stopped and bent his head, as if he was lighting a cigarette. A policeman who stopped to light a cigarette seemed the most unsuspicious policeman in the world. There was still no sound. There were bushes in the garden of the house where Rider had first heard it and he knew that a man could hide there out of sight. But if he went back, it would warn any such man. So instead he stood and shone his torch at the window nearest him, and as if he had noticed something unusual, he walked towards it and opened the wooden gate, which made no sound at all. He reached the entrance and shone the torch on the keyhole of the front door -- and as he did so, the rustle came again, this time much more softly. He looked round quickly. Question: When he heard the rustling sound, he _ . - thought that it was probably not caused by a dog - knew that he had disturbed a cat - knew not to take any notice of such a noise - realized that he had turned a corner
thought that it was probably not caused by a dog

Read the following article and select the best answer. Article: Who do you think was the most important woman of the past 100 years? Jane Addams (1860 - 1935) Addams helped the poor and worked for peace. She created shelters, education opportunities and services for people in need. In 1931, Addams became the first American woman to win the Nobel Peace Prize. Rachel Carson (1907 - 1964) Rachel Carson was born in the rural river town of Springdale, Pennsylvania in America. The popular 1962 book "Silent Spring" by Rachel Carson made people realize the dangers and the harmful effects of pollution on humans and on the world's lakes and oceans. Angela Merkel (1954 - ) In 2005, Germans chose Angela Merkel as their first woman head of the country. She had been a scientist in the past. As Germany's leader, she has had an effect on the whole world. Sandra Day O'Connor (1930 - ) When Sandra Day O'Connor finished her class at Stanford Law School, in 1952, she could not find work because she was a woman. However, she became the first woman to join the U.S. Supreme Court in 1981 after years of hard work. Margaret Thatcher (1925 - ) In 1979, Margaret Thatcher became Britain's first woman Prime Minister . She served until 1990, which made her the first British leader to serve three terms in a row. Because of her high standards and strong will, people called her Britain's Iron Lady. Marie Curie (1867-19245102534) Polish-born scientist Marie Curie discovered that some types of metal give off energy called radiation . Her research led to new medical treatments and arms. She received the Nobel Prize in Physics in 1903 and in Chemistry in 1911. Question: What do Angela Merkel and Margaret Thatcher have in common? - Both of them were scientists before coming to power. - Both of them are the first woman head of their country. - Both of them are famous for being strict. - Both of them have worked for three terms.
(Answer)
Both of them are the first woman head of their country.

Question: Read the following article and select the best answer. Article: For the first time, scientists have found a planet beyond the solar system that not only is the same size as Earth, but has the same proportions of iron and rock, a key step in an ongoing quest to find potentially habitable sister worlds. The planet, known as Kepler-78b, circles a star that is slightly smaller than the sun located in the constellation Cygnus , about 400 light years away. Kepler-78b was discovered last year with NASA's now-idled Kepler space telescope, which detected potential planets as they circled in front of their parent stars, blocking a bit of light. That measurement not only revealed that Kepler-78b was ly small, with a diameter just 20 percent larger than Earth's, but that it was practically orbiting on the surface of its host star. Scientists do not know how the planets ended up so close to their host stars. While the planet's presumably molten surface and hot temperatures make it ill-suited for life, two independent teams of astronomers jumped at the opportunity to follow up the discovery with ground-based measurements to try to determine the density of Kepler-78b. In two papers in this week's journal Nature, the teams report that not only were they successful, but that they came to the same conclusion: Kepler-78b has roughly the same density as Earth, suggesting that it also is made primarily of rock and iron. Kepler-78b is among a dozen or so recently discovered small planets that orbit very close to their parent stars. Kepler-78b, for example, completes an orbit in just 8.5 hours. Question: Which of the following is right according the passage? _ - Kepler-78b is a newly-found planet in the solar system - Although ly small, Kepler-78b has many properties that are similar to those of the earth - Kepler-78b has the same orbit circling the sun as the earth does - The earth is ly larger than Kepler-78b both in size and in diameter
Answer:
Although ly small, Kepler-78b has many properties that are similar to those of the earth
