Question: Read the following article and select the best answer. Article: Our body clock,or natural body rhythm,influences our energy and alertness.Paying attention to it can help us choose the suitable time of day when we best perform specific tasks. The reality,however,is that most of us organize their time around work demands,school deadlines,commuting or social events.Doing whatever your body feels like doing is a luxury in today's fast-paced modem society. But that doesn't mean it isn't worth trying.Obeying our body clock has significant health benefits.Disrupting our natural body rhythm,on the other hand,has been linked to problems such as depression,obesity,or headache,says Steve Key,a biology professor. When the body clock can synchronize(......)the rhythms of its natural processes,it "gives us an advantage in daily life",says Key. According to him,when it comes to cognitive work,most adults perform best in the late morning.As our body temperature starts to rise just before awakening in the morning and continues to increase until midday,our memory,alertness and concentration gradually improve. However,he adds,our ability to concentrate typically starts to decrease soon thereafter.Most of us are more easily distracted between noon and 4 pm. Alertness also tends to fall after eating a meal and sleepiness tends to peak around 2 pm,making that a good time for a nap. Surprisingly, tiredness may increase our creative powers.For most adults,problems that require open ended thinking are often best dealt with in the evening when they are tired, according to a study in the journal Thinking & Reasoning. When choosing a time of day to exercise,paying attention to your body clock can improve results.Physical performance is usually best from about 3 to 6 pm,says Michael Smolensky,a professor of biomedical engineering. Of course, not everyone's body clock is the same,making it even harder to synchronize natural rhythms with daily plans. Question: Which of the following is NOT true? - Our alertness is influenced by our natural body rhythm - Doing whatever your body feels like is very difficult in our modem society. - Obeying our body clock is good for our health. - Disrupting our natural body rhythm can lead to obesity.
Answer: Disrupting our natural body rhythm can lead to obesity.

Question: Read the following article and select the best answer. Article: Global Positioning Systems (GPS) are now a part of everyday driving in many counties.These satellite-based systems provide turn-by-turn directions to help people get to where they want to go. But, they can also cause a lot of problems, send you to the wrong place or leave you completely lost. Many times, the driver is to blame. Sometimes a GPS error is responsible. Most often, says Barry Brown, it is a combination of the two. Barry Brown is with the Mobile Life Centre in Stockholm, Sweden. The center studies human-computer interaction, or HCI, especially communications involving wireless devices. He told us about an incident involving a friend who had flown to an airport in the eastern United States. There he borrowed a GPS-equipped car to use during his stay. "And they just plugged in an address and then set off to their destination. And, then it wasn't until they were driving for thirty minutes until they realized they actually put in a destination back on the West Coast where they lived. They actually put their home address in. So again, the GPS is kind of 'garbage in garbage out'." Mr. Brown says this is a common human error. But, he says, what makes the problem worse has to do with some of the shortcomings, or failures, of GPS equipment. "One problem with a lot of the GPS units is they have a very small screen and they just tell you the next turn. Because they just give you the next turn, sometimes that means that it is not really giving you the overview that you would need to know that it's going to the wrong place." Question: In most cases, driving to wrong places or being lost is caused by _ . - the driver - GPS - the driver and GPS - strange places
Answer: the driver and GPS

Question: Read the following article and select the best answer. Article: What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science? We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop. The second is the application of the special methods of thought and action that scientists use in their work. What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves. He is a good observer, accurate, patient and objective and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum . He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively. Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation. Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place. These seem to be some of the ways in which a successful... Question: Which of the following statements about a curious scientist is TRUE? - He doesn't find confidence and pleasure in work. - He is interested in problems that are explained. - He makes efforts to investigate potential connections. - He looks for new ways of acting.
Answer:
He makes efforts to investigate potential connections.
