Read the following article and select the best answer. Article: What is time? Is it a thing to be saved or spent or wasted, like money? Or is it something we have no control over, like the weather? Is time the same all over the world? That's an easy question, you say. Wherever you go, a minute is 60 seconds, an hour is 60 minutes, a day is 24 hours, and so forth. Well, maybe. But in America, time is more than that. Americans see time as a valuable resource. Maybe that's why they are fond of the expression, "Time is money." To Americans, punctuality is a way of showing respect for other people's time. Being more than 10 minutes late to an appointment usually calls for an apology, and maybe an explanation. People who are running late often call ahead to let others know of the delay. Of course, the less formal the situation, the less important it is to be exactly on time. At informal get-togethers, for example, people often arrive as much as 30 minutes past the appointed time. But they usually don't try that at work. American lifestyles show how much people respect the time of others. When people plan an event, they often set the time days or weeks in advance. Once the time is fixed, it takes almost an emergency to change it. If people want to come to your house for a friendly visit, they will usually call first to make sure it is suitable. Only very close friends will just "drop by" unannounced. Also, people hesitate to call others late at night for fear they might be in bed. The time may vary, but most folks think twice about calling after 10:00 p.m. Question: The main idea of the passage is _ . - that Americans value punctuality - that in the USA time is limited and valuable. - the Americans attitude towards time. - the Americans' control over time.
the Americans attitude towards time.

(Question)
Read the following article and select the best answer. Article: Quick and Quack were two brave little ducks who lived with their mother. Both were really fast and were always competing against each other. One day, after visiting their uncle Ducklass, Quack shouted, "Last one home is a goose!" and both ducks swam quickly down the river. They both knew the way well, but Quack had been preparing a trick for some time. He had realized that the current in the middle of the river was stronger, and would help him. So, even though Mother Duck had told them never to swim in the middle of the river, Quack paddled over to it. "I'm old enough now to swim here," he thought to himself. It wasn't long before he realized his mother had been right. He was going much faster than Quick, and was developing a big lead. Quick was not amused. He never disobeyed his mother, and now he was going to lose the race! As they went on, the current got stronger. Quack proudly crossed the finishing line, without realizing he headed straight for a big whirlpool in the middle of the river. Before he could react, he was turning around in it, unable to escape. No duck was strong enough to swim in those waters, and poor Quack kept swallowing water. The fact that he was struggling hard didn't help matters much either. Fortunately, a cow from a nearby farm came by, and seeing Quack, he jumped in and rescued him. When he was on dry ground, he remained uncomfortable for quite some time. That provided quite a laugh for different animals that had been watching. Question: By saying "Last one home is a goose", Quack was _ . - encouraging a competition between himself and Quick - setting an example to Quick - expressing his desire to get home as soon as possible - warning Quick of the danger from their natural enemy
(Answer)
encouraging a competition between himself and Quick

Ques: Read the following article and select the best answer. Article: The vast majority of fitness trackers count your steps and are worn around the wrist, but now there's a device that's designed to be worn like a necklace and monitors tiny movements to improve your posture. The Fineck device aims to address neck pain by tracking tiny movement, spotting bad habits and suggesting exercises via an accompanying app. Made from silicone and titanium , Fineck monitors a wearer's movement, balance, posture and movement thanks to sensors inside. The Mountain View California-based firm says that a high percentage of people suffer from neck pain and associated problems, probably caused by more individuals doing office jobs, which generally involve leaning over computer keyboard. The device contains sensors, several different types of instruments to monitor movement, plus a monitor to shake. It connects to an IOS app via Bluetooth so that wearers can see their bad habits and play "neck training" games. The app warns of health risks and records a user's activity to build up a customer personal health description. The necklace shakes to give smart advice, such as reminding wearers to sit up straight. The app also allows users to set goals, like many other wearables do. "Fineck is the first wearable device for your neck that tracks your neck activity and warn you when you are in a bad posture for too long. You can also exercise your neck with Fineck's interactive games." The company writes on Kickstarter. "No matter where you are and what you are doing at office, on the go, or simply just feeling bored, Fineck will bring you enriched exercise experience through motion sensing games and therapies." It also claims that it is "the world's first titanium wearable device". The metal is widely used in fashion stuff that you can wear or carry to match your clothes because it is lightweight, durable and does not tend to cause allergic reactions. It also offers additional features such as shaking to indicate alerts on a user's smartphone, but it is not currently clear whether it can also be used... Question: Besides allowing people to set goals, the iOS app also _ . - improves your posture and suggests exercises - exercise your neck and does office jobs - alerts you to health risk and records your activity - counts your steps and addresses neck pain
Ans: alerts you to health risk and records your activity

Ques: Read the following article and select the best answer. Article: Ever feel like you've been hit on the head after a bad night's sleep? According to scientists, the thought isn't as unbelievable as it seems. A study found going without sleep for just one night causes changes in the brain similar to those that occur after a blow to the head. The researchers said the healthy young men examined in the study showed a sudden increase in the same chemicals which indicate brain damage. Professor Christian Benedict, of Uppsala University, Sweden, explained that the chemicals NSE and S-100B are biomarkers for brain damage, such as concussion . He said, "What we found was their levels in the blood rose in the group that went without sleep for a night. This was not to the extent that would happen after a head injury, for instance, but it was still significant. During sleep, the brain cleans poisonous substances off itself." Benedict also said previous studies which linked a lack of sleep with increased risk of Alzheimer's, Parkinson's and multiple sclerosis could applaud his study. The rise of the chemicals in the blood after sleep loss may suggest not getting enough sleep contributes to a loss of brain tissue, he explained. Benedict, whose study is published in the journalSleep, added, "In conclusion, the findings of our experiment indicate a good night's sleep may be critical to maintaining brain health." A third of the UK population suffer from sleep-related problems, while the average person now sleeps for only seven hours a night, compared with almost nine a few decades ago. Many scientists believe irregular sleeping patterns lead to illnesses ranging from aches and pains to heart disease, while less than eight hours' sleep a night can lower the IQ the next day. Question: What do we know about previous studies? - They found reasons for brain disorders. - Their findings were published inSleep. - They were supported by Benedict's study. - They focused on brain health.
Ans:
They were supported by Benedict's study.
