Example Input: Article: Shoppers who have cut back on purchases in the worrying U.S. economy are likely to continue their conservative shopping habits even if the economy improves, according to a new study. That signals continued bad news for retailers , who have been struggling to respond to a great cutback in spending as consumers have opened their wallets only for basic items, while cutting back on unimportant purchases. The report, which estimates retail sales growth to be flat this year, found that three-quarters of respondents to a monthly survey of 4,000 consumers said they had shifted their shopping behaviors because of the economy. Most said they were making do with less or going without some favorite items. "The habits learned during this economic crisis have the potential to permanently change the mind-set of consumers," the report said. "The vast majority of shoppers who are changing their near-term shopping behavior say they plan to continue them as the economy improves." To ease the consumer discomfort, smart retailers will focus on downsizing, the report said, as adding stores to an already crowded retail landscape is out of fashion. It came up with smaller initiatives to build shopping buzz, such as limited editions of products or having existing stores target local markets. The report also forecast that retailers will increasingly focus on private brands to attract cost-conscious shoppers, while adding complementary categories of goods to their stores to make one-stop shops for consumers. While warehouse clubs and super centers are expected to fare the best in the weak environment in 2009, discount department stores and supermarkets will be the weakest, the report warned. Sales of clothes, though expected to rebound in 2010, will be the hardest hit and slowest to recover.
Question: The current shopping behavior in the US is becoming _ .
Options: (A) arbitrary (B) protective (C) conservative (D) aggressive

Example Input: Article: In the market of luxury brands, Chinese consumers are only second to the Japanese in the world. Across the globe it's clear that the young generation are increasingly relying on expensive brands for their self-image. Personally I am a fashion-lover, at least in spirit. I love to look at clothes and shoes. But I don't understand why people spend large amounts of money on designer labels. Certainly, young people, whether in China or elsewhere, should be building their self-confidence in other ways. When a young woman shows off a handbag worth two months' salary, that's a scary thing. What are the psychological factors forcing young people to take on debt for designer items? The desire to say, "Hey, look at me. I'm wealthy. I have social status." Scientists have found the acquisition of luxury brands doesn't lead to happiness. Study after study has shown that, although we are born to desire material possessions, when we get them, we don't suddenly become "happy people". In fact, a series of studies by Leaf Van Boven at the University of Colorado, US, have shown that individuals who invest in travel and other experiences get more pleasure than those who invest in material things. That's because experiences are more easily combined into a person's identity. If I travel to Yunnan, that adventure affects how I think. My memories entertain my friends and colleagues. It follows, then, that investing in experiences improves my chances for successful social relationships. Moreover, as Van Boven has observed, young people who pursue happiness through "things" are liked less by others than young people who seek happiness through experiences. This research is pretty solid, but I suspect it won't persuade young people not to desire a style. It's natural to want to express yourself through your appearance. So my advice is, create a look that isn't tied to a designer label. You don't have to _ to send a message about who you are. Take a trip. Go out into the world. Then come back and confidently create your own signature look.
