Read the following article and select the best answer. Article: Just put your special clothes on in the morning and you could jump 3 meters into the air and even carry more than 60 kilograms without getting tired. The walk to school would be very, very easy. Such _ clothing is one of the products that could be created using "wearable robotics" technology. Designed to improve a person's senses and skills, the device could be as simple as a hearing aid. Or it could be a full-body suit that senses what you're going to do, then helps you do it better. "A superman suit would be the final result in wearable robot i cs ",s a id Francois Pin, head of robotics and energy systems at the Oak Ridge National Laboratory , US. While these suits are at least ten years away, in some areas the technology is already in use. Researchers are developing artificial- arms and legs that allow old,disabled or injured people to move freely. Thus US Army is interested in using wearable robot legs to help soldiers run faster, carry more equipment and be stronger in battle. Jobs that involve lifting heavy loads or saving lives from the rubble of an earthquake could also become much easier. A robot is a device that responds to a command. You're probably with simple robots, such as toy cars or airplanes that respond to buttons you push on a remote control. Wearable robotics goes further. Instead of just receiving information through a wire or remotecontrol- the robotic device can send information back to its controller. Suppose you wore a sleeve that has sensors where your joints are. Every time you move your arm, the sleeve senses your movements and sends the information to a robot, which then moves its arm just as you did. When the robot hits or touches something, it sends a signal back to the sleeve and you sense the action. In this way,scientists are working to wrap the robot around the person. Their goal is to make the sleeve, shoe or suit help you do what you want to do. Question: Products resulting from this wearable robotics technology do not include _ . - remote controls - hearing aids - wearable robot legs - superman suits
hearing aids

(Question)
Read the following article and select the best answer. Article: My friend had mentioned the other day that her father had a lot of children's toys he was looking to give away. She knew I have a three-year-old daughter so she thought of me first. I told her I would love it if I could get some nice things for my daughter, which I wouldn't otherwise have been able to afford. When I met her father, he began to explain he was too poor once and that he would hate to throw away things that can be very useful. Before he showed me what he was giving away, I thought the toys would be mostly lego's or things like that. When he was showing me around I saw a bed, a slide, a kitchen set and many other things that just blew my mind. He told me to write a list of everything my daughter could use and as my eyes were wide, he told me not to feel guilty. He said I was helping him by getting rid of the stuff. As I was looking around I did feel guilty, but I tried to remain more grateful than guilty. Every time I tried to thank him for giving me and my daughter all this wonderful stuff he would thank me right back. I wanted to believe that he was just thanking me so that I wouldn't feel so guilty but in reality I believe that he was as grateful as I was that these toys would be put to good use. In the eyes of charity, it makes sense to feel grateful, but guilt is just as normal. I know that we could have lived without a slide, which is why I do feel guilty, but I am grateful all the same because my daughter really does enjoy all these nice things! Question: Why did the old man want to give away his toys? - He wanted to help those poor children. - He was wealthy enough to buy new toys. - He wanted to make full use of those toys. - He needed some space for more useful things.
(Answer)
He wanted to make full use of those toys.

Ques: Read the following article and select the best answer. Article: Moods, say the experts, are feelings that tend to become fixed, influencing one's outlook for hours, days or even weeks. That's great if your mood is a pleasant one, but a problem if you are sad, anxious, angry or simply lonely. Perhaps the best way to deal with such moods is to talk them out; sometimes, though, there is no one to listen. Modern pharmacology offers a lot of tranquilizers What many people don't realize, however, is that scientists have discovered the effectiveness of several non-drug methods to set you loose from an unwanted mood. These can be just as useful as drugs, and have the added benefit of being nonpoisonous. So next time you _ don't head for the drug-store but try the following methods. Of all the mood-altering self-help techniques, aerobic exercise seems to be the most efficient cure for a bad mood. "If you could keep up the exercise, you'd be in high spirits, " says Kathryn Lance, author of Running for Health and Beauty. Researchers have explained biochemical and various other changes that make exercise compare favourably to drugs as a mood raiser. Physical exertion such as housework, however, does little. The key is aerobic exercise--running, cycling, walking, swimming or other repetitive and sustained activities that increase the heart rate, increase blood circulation and improve the body's use of oxygen. Do some of the activities for at least 20 minutes a session three to five times a week. Question: It can be inferred from the passage that _ - some drugs are more effective than physical exercises - a person does not need aerobic exercise if he is in a good mood - the best way to overcome a bad mood is to talk to oneself - when in a bad mood, one may not work very efficiently
Ans: when in a bad mood, one may not work very efficiently

Ques: Read the following article and select the best answer. Article: Fish species are expected to shrink in size by up to 24% because of global warming, say scientists. The scientists argue that failure to control greenhouse gas emissions will have a greater effect on marine ecosystems than previously thought. Previous research has suggested that changing ocean temperatures would affect both the distribution and the reproductive abilities of many species of fish. This new work suggests that fish size would also be heavily affected. The researchers built a model to see how fish would react to lower levels of oxygen in the water. As ocean temperatures increase, so do the body temperatures of fish. But, according to lead author, Dr William Cheung, from the University of British Columbia, the lower level of oxygen in the water is key. Warmer waters could decrease ocean oxygen levels and greatly reduce fish body weight. On the other hand, rising temperatures directly increase the metabolic rate of the fish's body function. This leads to an increase in oxygen demand for normal body activities. So the fish will run out of oxygen for growth at a smaller body size. The research team also used its model to predict fish movements as a result of warming waters. The group believes that most fish populations will move towards the Earth's poles at a rate of up to 35km per decade. "So in, say, the North Sea," says Dr Cheung," one would expect to see more smaller-body fish from tropical waters in the future." Taking these factors into consideration, the research team concludes that fish body size will shrink between 14% and 24%, with the largest decreases in the Indian and Atlantic oceans. When compared with actual observations of fish sizes, the model seems to _ what's actually happening in the seas. The researchers looked at two case studies involving North Atlantic cod and haddock. They found that recorded data on these fish showed greater decreases in body size than the models had predicted. Dr Alan Baudron, from the University of Aberdeen, UK, believes smaller-sized fish could seriously... Question: What is the key factor making the fish smaller now? - The rising body temperatures. - The lower level of oxygen in the water. - The increasing metabolic rate. - The normal body activities.
Ans:
The lower level of oxygen in the water.
