TASK DEFINITION: In this task, you're given an article, a question which often contains a blank, four options (associated with "A", "B", "C", "D") and the answer to that question. Your task is to classify whether the given answer is correct or not by providing "Yes" or "No", based on the article.
PROBLEM: Article: In spring, you may have seen white foam on a green tree or other plants. As a matter of fact, the foam is where young spittlebugs live. These insects are protected by the foam, and they usually don't do much harm to the plants. As we all know, in late summer, a mother spittlebug lays her eggs on the plant. The babies will hatch in spring. After they come to the new world, they begin to eat juice from the plant. The babies eat more juice than their bodies need for food. The extra juice mixes with a special waste that the spittlebugs produce. When this fluid is released, it mixes with the air, forming bubbly foam. What is so great about having a foam home? The space inside is so wet that it can keep the bugs' soft bodies from drying out. And the foam tastes bad, so it keeps away most animals that would eat the bugs. Some birds will reach their heads through the foam to find the bugs. Wasps and ants might eat them, too. But most of the bugs stay safe inside the foam. Once the bugs have grown into adults, they stop making foam. They leave their homes and jump from plant to plant in search of food. The adults look a little like tiny frogs. For this reason they are also called froghoppers. If you see some foam on a plant, you might want to take a careful look inside. Gently push some of the foam aside with a small stick. Deep inside you may see a few insects eating plant juice. They might also be making more foam. Be sure to push the foam back after a moment to cover the insects and keep them safe. Soon the spittlebugs will grow up and leave their foam home. They will join the other insects in the grassland.

Asnwer: B

SOLUTION: Yes

PROBLEM: Article: What doomed the Titanic is well known, at least in outline. On a moonless night of April 15, 1912, the ship hit an iceberg in the North Atlantic ,with 1,500 lives lost. A century later many people presented new theories to explain the real reason for the disaster. Now two new studies argue that rare states of nature played major roles in the disaster. The first says Earth's nearness to the Moon and the Sun -- a proximity not matched in more than 1,000 years -- resulted in record tides that help explain why the Titanic met with so much ice, including the fatal iceberg. Recently, a team of researchers found an apparent explanation in the heavens. They discovered that Earth had come unusually close to the Sun and Moon that winter, enhancing their gravitational pulls on the ocean and producing record tides. The rare orbits took place between December 1911 and February 1912 -- about two months before the disaster came about. The researchers suggest that the high tides refloated masses of icebergs traditionally stuck along the coastlines of Labrador and Newfoundland and sent them adrift into the North Atlantic shipping lanes. And a second, put forward by a Titanic historian from Britain, contends that the icy waters created ideal conditions for an unusual type of mirage that hid icebergs from lookouts whose duty was to watch carefully for danger ahead and confused a nearby ship as to the liner's identity, delaying rescue efforts for hours. Most people know mirages as natural phenomena caused when hot air near the Earth's surface bends light rays upward. In a desert, the effect prompts lost travelers to mistake patches of blue sky for pools of water. But another kind of mirage occurs when cold air bends light rays downward. In that case, observers can see objects and settings far over the horizon. The images often undergo quick distortions -- not unlike the wavy reflections in a funhouse mirror. Now, scholars of the Titanic are debating these new theories. Some have different opinions on it. Over all, though, many experts are applauding the fresh perspectives. (words:353)
Question: According to Theory Second, the disaster happened to the Titanic mainly because _ .
Options: (A) the freezing weather made the watcher not be able to watch clear (B) the mirage on the sea attracted the watcher and made him forget his work (C) the high tides drove the icebergs float so fast that the watcher didn't respond to them (D) the mirage made the watcher not find icebergs and a nearby ship delay rescuing
Asnwer: D

SOLUTION: Yes

PROBLEM: Article: One silly question I simply can't understand is "How do you feel?" Usually the question I asked of a man's action--a man on the go, walking along the street or busily working at his desk. So what do you expect him to say? He'll probably say, "Fine, I'm all right, " but you've put a bug in his ear--maybe now he's not sure. If you are a good friend, you may have seen something in his face, or his walk, that he overlooked that morning. It starts him worrying a little. First thing you know, he looks in a mirror to see if everything is all right, while you go merrily on your way asking someone else. "How do you feel?" Every question has its time and place. It's perfectly acceptable, for example, to ask "How do you feel?" if you're visiting a close friend in hospital. But if the fellow is walking on both legs, hurrying take a train, or sitting at his desk working, it's no time to ask him that silly question. When George Bernard Shaw, the famous writer of plays, was in his eighties, someone asked him, "How do you feel?" Shaw put him in his place. "When you reach my age, " he said, "either you feel all right or you're dead. "
Question: The question "How do you feel?" seems to be correct and suitable when asked of _ .
Options: (A) a man working at his desk (B) a person having lost a close friend (C) a stranger who looks worried (D) a friend who is ill
Asnwer: D

SOLUTION:
Yes
