Q: Read the following article and answer the question. Article: While parents, particularly mothers, have always been attached to their infants . societal conditions frequently made this attachment difficult to maintain . First of all, the high infant death rate in the premodern times meant that such attachments often ended in hopelessness. Perhaps to prevent the sadness that infant death caused, a number of societal practices developed which worked against early attachment of mother and child. One of these premodern attachment discouraging practices was to leave infants unnamed until they had survived into the second year. Another practice that discouraged maternal attachment was tightly wrapping infants. Wrapping effectively prevented the close physical interactions like stroking and kissing that are so much a part of modern mothers' and fathers' affection for their infants. A third practice which had the same distancing effect was wet-nursing. Breast-feeding was not popular among the well-to-do in the early modern times; infants were often fed by wet nurses hired for the purpose. In some places, such as nineteenth-century prefix = st1 /France, city infants were sent to wet nurses in the country. Often a wet nurse would feed her own child first, leaving little milk for the city infant-who, in many cases, died. In Rouen, the death rate for children sent to a wet nurse was 35 percent Question: Which is the best title for the passage? Answer:
Answer: Practices of Reducing Matemal Attachment

Q: Read the following article and answer the question. Article: You are careful with your money: you collect all kinds of coupons; look for group-buy deals if you eat out; you don't buy clothes unless in a sale. Does all this make you a wise consumer? Let's do the math first: you walk into a coffee shop and see two deals for a cup of coffee. The first deal offers 33 percent extra coffee. The second takes 33 percent off the  regular price. What's the better deal? Well, they are about the same, you'd think. And you'd be wrong. The deals appear to be equal, but in fact, they are different. Here's the math: Let's say the standard coffee is 10 yuan and let's divide the amount of coffee into three portions . That makes about 3.3 yuan per portion, The first deal gets you 4 portions for 10 yuan (2.5 yuan per portion) and the second gets you 3 portions of coffee for 6.6 yuan (2.2 yuan per portion) and is therefore a better deal. In a new study published by the Journal of Marketing, participants were asked the same question, and most of them chose the first deal, the Atlantic website reported. Why? Because getting something extra for free feels better than getting the same for less. The applications of this view into consumer psychology  are huge. Instead of offering direct discounts, shops offer larger sizes or free samples. According to the study, the reason why these marketing tricks work is that consumers don't really know how much anything should cost, so we rely on parts of our brains that  aren't strictly quantitative. There are some traps we should be aware of when shopping. First of all, we are heavily influenced by the first number. Suppose you are shopping in Hong Kong. You walk into Hermes, and you see a 100,000 yuan bag. "That's crazy." You shake your head and leave. The next shop is Gucci, a handbag here costs 25,000 yuan. The price is still high, but compared to the 100,000 yuan price tag you just committed to your memory, this is a steal. Stores often use the price difference to set consumers' expectation. zxxk Another trap we often fall to Is that we are not really...

Q: Read the following article and answer the question. Article: A beer bottle thrown from the stands landed near Usain Bolt in the moments before the 100-meter final Sunday night in London. As Bolt and seven other competitors ducked into their starting crouches, a bottle sailed from the first row of the stands at Olympic Stadium. It harmlessly bounced in the lane belonging to Yohan Blake and didn't appear to cause a distraction  to the runners, who started a moment later. The thrower's lack of distance was a blessing. Had he gathered tips from the competitors of the hammer throw  competition, which was taking place in the infield at the same time as the 100 final, the bottle could have hit one of the competitors. It ended up landing a few feet from Blake (lane5). Edith Bosch, a female Dutch judoka who won a bronze medal earlier during the Olympics, claimed that the man who threw the bottle was sitting near her and that she "beat" him. Whether that's true or the hyperbole   of an aggravated athlete was unclear in the minutes after the incident. Pictures show a group of Dutch athletes sitting behind the starting area. Police took the man into custody . He will appear in court on Monday morning. Neither Bolt nor Blake said they knew of the incident until they were informed by reporters. "I don't know who would have done that," Bolt said. Gatlin was aware of it but implied it was only a slight distraction. "I didn't know what it was," he said, according to the BBC, "but when you're in those blocks, the whole stadium is so quiet that you can hear a pin drop."
