I'm taking a test and have to guess the right answer to the question after the article. 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: The best title for the passage may be " _ ". Options: A: Warm lava on Venus B: More volcanic eruptions on Venus C: Venus is just like a big active volcano D: Lava flows are first found on Venus

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: There's no doubt that man is the smartest. But do you know what other animals are smart, too? Dolphins Dolphins are very smart. Most of the "tricks" they're taught to do are actually behavior they would engage in on their own. They love to play, race and generally enjoy their life to the fullest. They speak a language we have yet to completely understand and like all civilized creatures, dolphins' mothers always provide their young children with guidance and possibly, love. Great apes The great ape family primarily consists of gorillas, chimpanzees and orangutans. Their brain chemistry is so similar to humans' that NASA once used chimpanzees in place of astronauts during many dangerous missions. Gorillas have been taught sign language and orangutans exist in complex familial relationships. Elephants Everyone has heard the phrase "an elephant never forgets". Elephants establish long-term friendships, recognizing and remembering their friends years later. If an elephant comes upon a fallen friend, it has even been known to feel sad. Parrots As proved by this list, parrots are very smart. They are also the only animals listed that can actually hold a conversation. Some parrots know hundreds of words by imitating humans. The birds are also capable of remembering words and using them intelligently in response to situations. Question: Which of the following is TRUE about dolphins? Options: A: They are able to play a lot of tricks. B: Humans know well of dolphins' language. C: Their brain chemistry is similar to humans'. D: Dolphins' mothers care little about their children.
Ans: A
I'm taking a test and have to guess the right answer to the question after the article. Article: The year is 2094. It has been announced that a comet is heading towards the earth. Most of it will miss our planet, but two pieces will probably hit the southern half of the earth. On 17 July, a piece of 4 kilometers wide comet enters the Earth's atmosphere with a massive explosion . About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the seabed. Huge waves are created and spread outwards form the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned . Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes ash set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won't escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. The sun won't be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive. Could it really happen? In fact, it has already happened more than once in the history of the earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn't live through the cold climate that followed and they died out. Will we meet the same end? Question: When the first piece hits the South Atlantic, it causes _ . Options: A: an earthquake B: hunger C: an Earth explosion D: huge waves
