Article: If you were on the street in Mexico today you might think you were in an operating room, surrounded by doctors. You could see many concerned people with masks trying their best to stop the swine flu . And the masks aren't only being used in Mexico. A friend of mine traveling from New York City to Florida was given a mask and a pair of gloves just after he reached the airport. And another friend went to get a haircut only to be faced with a hairdresser wearing a mask! But do the masks really work? Is covering your nose and mouth the key to stopping the swine flu? To find out the truth, ABC's reporter Sharyn Alfonsi talked with germ expert Dr. Elaine Larsen. It turns out that when you sneeze the air coming out of your mouth at a speed of one hundred miles per hour carries germs which can travel anywhere around you and make people around you infected . However, whether you become infected actually depends on the weather. As Sharyn reported, when you sneeze, the germs leave your body in small drops of water coming out of your mouth. If the weather is wet, the wet air will make the small drops bigger and heavier and they drop down towards our feet. If this happens, we won't become infected. But if the air is dry, those small drops can float higher up, making it possible for them to touch someone else's nose, mouth or their mask. Larsen says the masks can stop the germs well but after a few hours, they start to get wet, holding a lot of germs they come across and causing you to breathe them in. The masks do work, but the key to stopping the germs is changing your masks often. Question: If you keep wearing a mask for a long time, _ . Answer:
A:
output: it will be easy for you to be infected

input: OPTIONS:
- To tell old people how to remove their terrible scent.
- To prove that people often hold wrong ideas.
- To show how researchers carried out their study about the scent.
- To report the findings of a study about people's scent. Now, answer this question: Read the following article and answer the question. Article: A study found that young people have a stronger and more unpleasant scent than the elderly,while elderly people's smell was the most distinctive,less intense and unpleasant. Researchers said the change in our smell is driven by the chemicals we release through our glands and the bacteria on our skin. To test whether or not it really exists,scientists collected a series of samples from three groups of 12 to 16 donors,aged 20 to 30,45 to 55 and 75 to 95.Volunteers wore special T-shirts fitted with underarm pads as they slept for five nights,after which the pads were cut up and put in glass jars. A separate group of 41 people aged 20 to 30 was then asked to smell two jars at a time and asked which group of the donors was older,as well as rating how strong and unpleasant each smell was. When asked to specify whether a particular sample was from a young,middle aged or old person,they were much more successful at identifying older people. Despite being the most distinctive,the older people's smell was also rated as being obviously less intense and less unpleasant than those from the other groups. Researchers said their findings appeared to contradict people's negative ideas about the old person's smell but admitted other factors,like smelly breath or skin,could be to blame for its bad reputation. "Similar to other animals,humans can give off body scents that allow us to identify biological age,avoid sick individuals and pick a suitable partner. Elderly people have a distinctive scent that younger people consider to be not very unpleasant. This was surprising given the popular conception of old age scent as smelly. However,it's possible that other sources of body scents,such as skin or breath,may have different qualities," said Dr Johan Lundstrom,who led the study. Question: What is the author's purpose in writing this passage? Answer:
A:
output: To report the findings of a study about people's scent.

input: OPTIONS:
- Shakespeare got inspiration to write from his hometown, London.
- Shakespeare was eager to make friends with the noblemen in London.
- Shakespeare became the greatest dramatist owing to his own genius.
- Shakespeare was good at observing and learning from the daily life. Now, answer this question: Read the following article and answer the question. Article: When Shakespeare was twenty-one, he went to London to try his fortune in that great city, and a very interesting place was the London of his day. There was the famous London Bridge and St. Paul's Cathedral, and palaces and markets and long streets full of shops. Then, too, there were the daily crowds where people from all over the world could be seen. Knights,scholars and the highwayman or thief,who had been infamous for his clever robberies, passed by each other. Here, also, were noblemen dressed in gold, from Italy and Spain and France; slaves from Spanish America, sea captains and ministers, soldiers and servants--all held by chance or interest within the gray walls which circled London, and whose gates gave welcome to as strange a crowd as could be found in the world. Into this curious crowd came Shakespeare, quick to see and eager to learn. And before long all these strange sights were as familiar to him as the faces of his own town's residents. Each _ told its story to him so plainly that, as before he had learned the secrets of the fields and woods, so now he learned men and men's interests that make up the great world. And he learned these lessons so well that when he came to write his plays, he made such use of them as no writer ever made before or since; for it is the use of this knowledge of the world, combined with his own genius, that makes Shakespeare the greatest dramatist that has ever lived. Question: Which of the following best describes Shakespeare? Answer:
A:
output:
Shakespeare was good at observing and learning from the daily life.
