I'm taking a test and have to guess the right answer to the question after the article. Article: Every year, millions of Americans see their personal information leak into the wrong hands. Maybe there's spyware on the their computer, or a service they use suffered a security reach, leaving customers at the risk of exposure. Or perhaps their password is easy to guess. Don't fear: You can easily set up proper defenses. Here's how. * Clean Your Computer and Smartphone Before you put new security measures into place, make sure your devices are as spotless as possible. This means installing a good antivirus program and taking the time to clear out any spy -- or malware that may have already infected your system. These days, it's also worth it to make sure your phone is safe from viruses. Iphones are less likely to be targeted by spyware, but Android users should download the Lookout app to scan their devices and ensure everything is as it should be. * Secure Your WiFi. It's fairly easy for potential criminals to gain access to your information if they're able to share your connection -- that's why you want to be careful when using public WiFi. Even though you put security measures into place a couple of years ago, it's a good idea to refresh your settings. * Use passwords What you've heard is true: Passwords should use a variety of special characters, numerals, letters, and cases when possible. * Check the shopping security Take care when shopping online. Always check the security symbols when using an online site for shopping. If the lock icon encryption is not there, do not give out credit details. Also, check that the site is legal -- never go to a site from a random email and start shopping online. Keep a separate credit card just for online shopping. This will make it easier to cancel if something bad does happen and your other credit card for "in real life" can still be used uninfluenced. Don't store information on any store's website. It may be convenient but it's also a possible loss to you if the site is hacked. Question: This passage is mainly about _ . Options: A: ways of avoiding identity theft B: tips of freeing computers from viruses C: measures to ensure network security D: steps to keep track of passwords

I'm taking a test and have to guess the right answer to the question after the article. Article: America has been experiencing the longest economic increase in its history. Incomes have risen, unemployment has fallen, and cities such as New York are bursting with new office buildings. But just a short walk from Manhattan's skyscrapers, George Brown sits on the side-walk, cooking a lunch of rice and bits of fish over a can of cooking fuel. Brown is homeless----one of the 2.3 million people in the US who end up on the street. During the day, Brown collects aluminum cans and sells them for five cents a piece. At night, he sleeps on the street. "I have been on the street about eight or nine years, something like that," said the 62-year-old former construction worker. Brown admits he had problems with alcohol and has smoked cocaine. But he said he still wants a more stable housing arrangement. He could afford it just with the money he earns by collecting cans and small pieces of metal, if only truly low-income housing were available. However, he sees no hope of finding affordable housing in New York. With the strong economy and unemployment down, beautiful housing is being built to meet demand. A US report shows rents in New York City rose more than 27 per cent, from $549 to $700 a month. One of the side effects of the strong economy is that rents have been going up. The majority of people who experience homelessness really just need some affordable housing help. But few housing companies are building for the poor. Many small apartments in the city now rent for $1,500 a month or more. Brown, the homeless New Yorker, said he has a daughter who lives in the city but he rarely sees her. She is angry about his drinking and won't allow it in her house. Smiling, he said he also has seven grandchildren whom he'd like to see more often. "All I've got to do is _ ," he said. Question: What kind of life does George Brown lead? Options: A: Stable. B: Dangerous. C: Hard. D: Comfortable.

I'm taking a test and have to guess the right answer to the question after the article. 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: If we know our natural body rhythm well, we can _ . Options: A: find out the suitable time to do specific tasks B: organize our time around work demands C: do whatever our body feels like doing D: be sure to be healthy
