Men have always believed that they are smarter than women. Now, a study has found that while this is certainly true, men also have to deal with the fact that they are also more stupid than the fairer sex. In the study, scientists measured the IQ of 2500 brothers and sisters and they found an uneven number of men not only in the top two percent, but also in the bottom two percent. The study's participants were tested on science, maths, English and mechanical abilities. Though there were twice as many men as women in the smartest group, there were also twice as many men among the foolish. The total scores of men and women were similar. One of the study's authors, psychology professor Timothy Bates, said that the phenomenon may be because men have always been expected to be high achievers and women have been restricted to spend more time taking care of their home. "The female developmental program may be tilted more towards ensuring survival and the safety of the middle ground."the Daily Mail quoted Professor Bates, of Edinburgh University, as saying. The research agrees with past results that men were more likely than women to receive first class University degrees or thirds and women secured the seconds. It has been said that men are more ready to take a risk when it comes to academics. While women have always been found to be steadier in their learning. A past study has shown that women are securing more firsts and seconds, while men are continuing to receive more thirds. The argument for the change is that the increase of coursework at the cost of exams favors women's steady approach. The reason for the change that women are securing more firsts and seconds is that. A) More women are growing like men B) .higher expectation is given to more women C) Women's steady approach is more suitable for the exams D) More women have the chance to receive first class university

Children with autism have difficulty with social skills and communication. They often behave in restricted and repetitive ways and have what seem like abnormally intense interests. Autism is more common in boys than girls. What causes it is not clear. Scientists are studying genes and possible environmental influences. Doctors usually cannot confirm a diagnosis of autism until a child is about three years old. Rebecca Landa is a researcher at the Kennedy Krieger Institute and Johns Hopkins University School of Medicine in Maryland. Professor Landa wanted to find out what differences in development might be seen earlier. She led a new study that observed 235 babies between six and 36 months of age. "At six months of age, the signs of some risk for developing communication and social delays, including autism, include motor delays. Like when you lay your baby on their back and you pull them by the arms gently into a seated position, the baby's head may nod back behind the shoulders, like poor head control. So that does not mean that the baby is going to have autism, but it does mean the baby needs to have some exercises to strengthen their body. And when they strengthen their body, they are better able to play with toys and engage with people, which then goes on to help them have better outcomes." By the time a baby is one year old, signs of possible autism include difficulty in using words and not looking eye-to-eye or reaching out to other people. By 14 months, the baby might smile less and use language less. However, Professor Landa says these signs can be so small that they might be missed during a short health exam. "It's important for parents to stay tuned into their children's development, and if a parent is concerned about a child's development, for professionals to listen to them." The earlier parents notice delays, she says, the sooner they can begin doing simple things that may help improve their child's development. For example: talking to the child about what they are doing, commenting when the... When a baby with signs of possible autism is a year and two months, he may _ . A) avoid eye contact B) have difficulty in raising his head C) develop bad manners D) hate to communicate with others

Ques: Scientists have created a " human-like robot" that can dance and do the housework. " Mahru" has been developed to imitate humans and can move its lips, eyebrows and pupils . The machine can also move its upper and lower body freely and automatically stop itself when walking. In addition, it has been programmed to give out two kinds of pleasant smells to match its emotions. The 1.5 tall robot was produced by researchers at the Korea Institute of Science and Technology (KIST) and is the first South Korean- developed machine of its kind. "'Mahru' will open the way for the commercial use of humanoid robots doing housework," You Bum-Jae, leader of the development research team ,said. "'Mahru' can dance while walking on its legs and is able to work in place of a human." Through an advanced motion capture system, "Mahru" can follow a variety of human movements and move its hands freely enough to deal with any obstacles that may get in its way when walking. State-funded KIST showed the robot during a presentation at its head office in Seoul. People here were treated to an entertaining demonstration which saw the robot show off the full range of its skills, most notably s series of dance moves. The research team added that they had designed another " Mahru", this time with sensors allowing it to distinguish between faces and objects. The showing of " Mahru" came a week after researcher in Japan said they had created the "most human-like" robot in the world. A team at robotics department of Osaka University in Japan claimed that " robogirl", Repliee R-1, " looks, moves and interacts like a human, and has silicone skin that feels almost human to the touch." "Mahru" made by KIST can do the following things EXCEPT _ A) dance with other human -like robots B) move its body freely C) stop automatically when walking D) express certain feelings through smells
Ans: A
Ques:Since I started working part-time at a grocery store, I have learned that a customer is more than someone who buys things. To me, a customer is a person whose memory fails entirely once he or she starts to push a shopping cart. One of the first things customers forget is how to count. There is no other way to explain how so many people get in their express line, which is clearly marked 15 items or less, with 20, 25 or even a cart load of items. Customers also forget why they came to the store in the first place. Just as I finish ringing up an order, a customer will say, "Oops, I forgot to pick up a fresh loaf of bread. I hope you don't mind waiting, while I go to get it."Five minutes later, he's back with the bread, a bottle of milk, and three rolls of paper towels. What is strange is that customers also seem to forget that they have to pay for their groceries. Instead of writing a check or looking for a credit card while I am ringing up the groceries, a customer will wait until I announce the total. Then, in surprise, she says, " Oh no, what did I do with my check book?" After 5 minutes of digging through her purse, she borrows my pen because she has forgotten hers. But I have to tolerate customers because they pay my salary, and that's something I can't afford to forget. According to the text, who are supposed to be in the express line? A) Customers with nothing purchased. B) Customers with not more than 15 items. C) Customers with items between 16 and 25 D) customers with 25 or even a cart load of items.

Ans:
B
