Question: Read the article and select the best answer. Article: Scientists know of more than 1,000 volcanoes on the surface of Venus, Earth's "sister" planet. A big question has been: Are they still active? The scientists say yes. Their evidence for recent volcanic activity on Venus comes from a lava flow in the planet's northern hemisphere. The flow is hotter than the rocks around, which means the lava might still be cooling off. "The flow we studied seems to be very young---it is still warm inside," Nataliya Bondarenko said. Venus is a difficult planet to study from Earth because it is surrounded by thick clouds. Telescopes on Earth can't see through these clouds, so the best information about Venus comes from spacecraft orbiting it. Bondarenko and her colleagues studied the lava flow using data from NASA's Magellan mission. That spacecraft spent four years in orbit around Venus and used radar to make a map of 98 percent of the planet's surface. On October 11th, 1994, the mission ended, and the spacecraft plunged through Venus' heavy cloud cover and crashed onto the planet below. While in orbit, the Magellan craft sent microwaves, which can go through Venus' clouds, to the surface. Microwaves are invisible and can be as long as three feet. These waves are a kind of energy, like light. And like light, they bounce off surfaces. The way the waves bounced off the Venus' surface and back to the craft supplied information that the scientists used to estimate the temperature of various parts of the planet's surface. Bondarenko's team found that the lava flow was hotter than its surroundings---which may mean the lava flow is in the process of cooling. The scientists say the lava flow can't be very old because if it were, it would have cooled off enough that Magellan wouldn't have noticed the difference in microwaves. She adds that the flow appears in a 1978 view of the surface that a craft called the Pioneer Venus Orbiter captured. Question: What happened to Magellan in the end? Options: A: It was floating in space forever. B: It flew into heavy clouds. C: It returned to the Earth. D: It fell onto Venus.
Answer: D

Question: Read the article and select the best answer. Article: Googlefight is a simple service available on the Internet which offers you the chance to compare two different items and see how many hits they get on the Google search engine. The seemingly simple device has proved invaluable to users, especially to help win arguments. For example, imagine that you and your friends are arguing about who are the most popular music or movie stars, you can decide the argument by writing the names in the Googlefight boxes. Let's say that you are arguing about Jackie Chan and Jet Li. You will quickly discover that Jet Li is mentioned 16 million times on Google pages, whereas Jackie Chan is mentioned a mere 12 million times! In this unscientific way, you can claim victory for one Star over another. But teachers have come up with ways of using Googlefight which are much more useful from an academic point of view, particularly when it comes to studying languages. You can, for example, find out the frequency of two words with the same meaning, and deduce from the answers which one is more common. For example, let's take the words "buy" and "purchase", which mean the same thing (although "buy" is only a verb and "purchase" is both a verb and a noun). It is immediately clear from Googlefight that "buy" is much more commonly used, with a massive three and a half billion hits, compared to only one billion occurrences for the more formal word. But the real value of Googlefight to the language learner is in determining which is the more common of two phrases. For example, "raining cats and dogs" is an old-fashioned English expression about the weather. Do English speakers still use it? Or are they more likely to say "pouring down"? Googlefight suggests the latter. "Pouring down" has 898,000 Google hits, whereas "raining cats and dogs" only has 326,000. With phrases, it's important to remember that you need to use quote marks to make the search more accurate. For example, if you type in the similar phrases "look after" and "take care of " without quote marks, the second phrase seems to be... Question: Language teachers find it useful because _ . Options: A: there are a lot of words on Googlefight B: it can tell them which of the two words with the same meaning appears more often C: some words mean the same thing D: common words have a billion hits
Answer: B
