Although my thoughts were only on speed, the checkout line I was standing in wasn't moving as quickly as I wanted, and I glanced toward the cashier. There stood a man in his seventies, wearing glasses and a nice smile. I thought, well, he's an old guy! For the next few minutes I watched him. He greeted every customer before scanning the items. Sure, his words were the usual, "How's it going?" But he did something different--he actually listened to people. Then he would respond to what they had said and engage them in brief conversation. I thought it was odd. I has grown accustomed to people asking me how I was doing simply out of robotic conversational habit. After a while, you don't give any thought to the question and just mumble something back. I could say, "I just found out I have six months to live," and someone would reply, "Have a great day!" But that wasn't the end. He gave them the change, walked around the counter, and extended his right hand in an act of friendship. He looked the customers in the eyes. "I sure want to thank you for shopping here today," he told them. "You have a great day. Bye-bye." The looks on the faces of the customers were priceless. There were smiles and some sheepish grins. All had been touched by his simple gesture--and in a place they never expected. They would gather their things and walk out, smiling. Of course, he did the same to me and I got to know his name--Marty. Who was that guy? It was as if Sam Walton had come back from the dead and invaded this old guy's body. I had never walked away from that shop feeling like that. Question: What can we infer about Sam Walton? - He might be Marty's father or grandfather. - He might have died while working in the market. - He might be friendly and devoted to Wal-Mart. - He might have come back from the dead once before.
He might be friendly and devoted to Wal-Mart.

Read the following article and select the best answer. Article: An aspirin a day keeps the doctor away. Aspirin has long been praised as a wonder drug and has been in your family since you can remember. Not only does it cure pain, it also lowers the risk of heart attack and stroke . But taking the pills daily may not work for everyone. Although taking an occasional aspirin or two is safe for most adults to use for headaches,body aches or fever, daily use of aspirin can have serious side effects. Up to 60 per cent of us,both healthy people and those being treated for all types of heart disease, may have some level of resistance to aspirin' s benefits. Aspirin keeps platelets from sticking, lowering the risk of clotting . People who are aspirin - resistant still get pain relief but not the full blood - thinning effects. How do you know whether you' re resistant? New blood tests can help your doctor decide whether to give you a different medicine, especially if you' re at risk or are being treated for heart disease. The tests aren' t yet widely available, but it doesn' t hurt to ask. People taking aspirin daily should limit the amount of alcohol they drink because of its additional blood - thinning effects and potential to upset your stomach. Thus you should not have more than one drink if you' re a woman or two dr/nks a day if you' re a man. Does daily aspirin treatment differ between men and women? Recent studies have focused on the effects of aspirin in women, finding that its effects differ between the sexes, and for women, between age groups. All in all, aspirin is still an effective, affordable and simple option for many people at risk of heart attack and stroke. Though it is readily available, always check with your doctor before starting daily aspirin treatment. Question: What does the writer think of taking aspirin daily? - People should be careful to make this decision. - This treatment is effective, affordable and simple. - It could be used to cure heart attack and stroke. - Old women should not start this kind of treatment.
(Answer)
People should be careful to make this decision.

Question: Read the following article and select the best answer. Article: After a fortnight of extraordinary type, the much-feared computer virus that was supposed to strike the globe's hard drives last Friday simply fizzled. So many warnings were sounded that most computer owners either fed anti-virus programs into their systems or refused to turn the power on during the dreaded M-day. They dodged one disease, but more strains are on the way. The eponymous Friday-the-13th virus is due to strike this week, and the Maltese Amoeba may detonate on March 15. Who creates these things? A disproportionate number seems to originate in Bulgaria or Russia, where writing the smallest, most elegant virus programs has become a matter of quirky pride. Viruses are transmitted either by shared disks (as was Michelangelo) or over telephone lines. The virus program hides in a computer until, activated by a date, time, or some other trigger, it springs to life. The most common virus, Stoned, makes your screen announce: "Your computer is now stoned. Legalize marijuana. " (Regardless of your politics, you don't want this one around; it can damage your files inadvertently.) Solution: either keep your computer isolated--no trading disks, no on-line communication--or else install one of a dozen or so commercially available anti-virus programs that detect and delete the little time bombs. If they can come up with a virus that is hidden, will they next try to extort a business?--as in, pay me $1 million or my virus will destroy your system. In the meantime, money is being made by firms selling anti-virus programs. Egghead software stores logged a 3,000 percent jump in anti-virus sales. Was the threat overblown by the companies that make millions selling anti-virus software? Thanks to the media blitz, no one will ever know what might have happened--an unallied number of computer owners discovered and deleted Michelangelo before it was supposed to strike--on the artist's birthday. Question: Which of the following sayings fits the Michelangelo virus? - A burnt child dreads the fire. - The bug's bark was worse than its bite. - A barking dog seldom bites. - Once bitten, twice shy.
Answer:
The bug's bark was worse than its bite.
