According to a new study, a baby's cry can make adults react very quickly, even if they are not related. Oxford University researchers used the classic game whack-a-mole for the study. Whack-a-mole requires people to hit one of nine buttons . The players must react as quickly as they can to whichever of the buttons lights up at random . It is a game that requires speed and accuracy ( ). The study included 40 men and women volunteers aged 19 to 59. Some of them had sons or daughters but none had a baby at the time. They played whack-a-mole after listening to different sounds, including babies crying, the crying of adults in trouble and birdsong played at a similar pitch to the babies' cries. The volunteers' scores were higher after listening to the sound of crying babies. Men and women had similar scores overall. The results showed that a crying baby gets special attention. "Few sounds make people react quite like the cry of a baby," said Morten Kringelbach of Oxford's psychiatry department, who led the study. "For example, it's almost impossible to ignore(,) crying babies on planes. This is true even though there are so many other noises around." He added that a baby's cry can increase adults' heart rate and blood pressure. This is understandable, because in the course of human evolution , taking care of babies has always been an important job for adults. When a baby is hungry or feeling bored or unwell, it will cry. As a result, human brains and bodies develop a special reaction to a baby's cry. Question: The game "whack-a-mole" shows _ . - a baby's cry can get special attention from adults - men and women have different reaction speed and accuracy - adults without babies react less quickly to a baby's cry - women react to a baby's cry more quickly than men
a baby's cry can get special attention from adults

Q: Read the following article and select the best answer. Article: Americans have used colours to create many expressions they use every day. We say we're "in the pink" when we are in good health. It is easy to understand how this expression was born. When my face has a nice fresh, pink colour, it is a sign which shows my health is good. The colour green is natural for trees, it is an unnatural colour for humans. When someone doesn't feel well, for example, we say he looks green. When someone is angry because he doesn't have what someone else has, we say he is "green with envy". Some people are "green with envy" because someone else has more dollars, or "greenbacks". Dollars are called "greenback" because that's the colour of the backside of the money. Blue is a cool colour. The traditional blue music of American blacks is the opposite of red hot music. It is slow, sad and soulful . To be blue, of course, is to be sad. The colour black is often used in expressions. People describe a day in which everything goes wrong as a "black day". A "black sheep" is the member of a family or group who always seems to be in trouble. If someone meets a "black cat", something unlucky might happen to him. Not all the "black" expressions have bad meanings. A company "in the red" is losing money. If someone tells you to put someone "in black and white", they want you to write it down. Question: My brother is _ of our family, everyone hates him. - a black horse - a black cat - a black dog - a black sheep
A: a black sheep

Q: Read the following article and select the best answer. Article: In April, 2013, I visited Yangzhou. Ge Garden is very beautiful and peaceful. The ticket has a map on the back of it that I didn't noticed until I had already left. But to be honest, I don't think that map is very useful because it isn't very clear an tailed. In my opinion, it's better to improve it. Compared with He Garden, the map on the back of the ticket for He Garden is much clearer, more detailed and more useful. However, in the room that has the picture of the family members, there is only Chinese, no English, so my advice is to add English in interesting places. I got lost in the Slender West Lake. I spent about 30 minutes just trying to get out of one area. I think they need more signs posted along the trails. I like the Slender West Lake best, as she is so pretty! The ladies that were sweeping were very sweet. They always smiled at me and said hello, so it was nice. Taking a taxi is the most efficient and quickest way to get around Yangzhou. I didn't have a problem getting to the places which I'd like to go to while using a taxi. The driver was very friendly. The fare isn't too high, either. But I didn't enjoy taking the bus. The bus ride to the Mastixia Bay took long although I only had to pay one yuan. It was also hard finding where Bus 32 was. I tried asking some people in English but they couldn't understand me, so I had to ask in simple Chinese that I only know buy that still didn't work. I spent about one hour walking around the city to look for Bus 32. The tricycle was nice, but it was a little too expensive for a small distance. Maybe I was _ by the guy who rode for me, but it was an enjoyable ride. I felt like I was part of the garden city more. Over all I am satisfied with Yangzhou and will recommend it to others. Question: We can infer the passage may be written by _ . - a foreign visitor - a lady sweeping in the park - a taxi driver - a guy riding a tricycle
A: a foreign visitor
