Q: Article: Although Paris is often considered the city of romance, close to a million adults who call it home are single. Many single people say that France's capital is one of the most difficult places to meet people. The complaints of this lonely group have inspired a new phenomenon known as "supermarket dating." At Galerie Lafayette Gourmet,singles can shop for more than just the items on their grocery list. They can look for someone who has blue eyes, brown hair,and is 1.8 meters tall,or whatever may be on their romantic shopping list. At this Paris location,single people of all ages can schedule their shopping for Thursday nights between 6:30 and 9:00 p.m. When they walk through the door,they pick up a purple basket to advise that they are looking for love. They try to arrive early because the baskets disappear quickly, and then they have to wait in line for their turn to wander the store aisles . With purple baskets in hand, shoppers can consider their romantic options while they pick out their groceries. When they are ready to pay, they can go to the checkout line for singles who want to chat. Most of the people who look for love in the supermarket are skeptical of Internet dating. They know that it is easy to embellish one's appearance or to lie about one's age over the Internet. The supermarket, on the other hand,is considered a safe and casual environment in which to meet a potential match. In addition, what one finds in another's grocery basket can say a thing or two about that person's character or intentions. Buying pet food can be a man's way of showing a potential match that he has a sensitive side. Women who fill their baskets with low-fat food show their healthy style of living. These ways it's possible to find much more than food at a grocery store.
Question: What do many single people in Paris complain about?
Options: (A) The difficulty in meeting people. (B) The idea of supermarket dating. (C) The items on their grocery list. (D) The inconvenience in shopping.

Q: Article: Sensing phantom phone vibrations is a strangely common experience. Around 80% of us have imagined a phone vibrating in our pockets when it's actually completely still. Almost 30% of us have also heard non-existent ringing. Are these signs of madness caused by digital culture? Not at all. In fact, phantom vibrations and ringing indicate a fundamental principle in psychology. Psychologists use a concept called Signal Detection Theory to guide their thinking about the problem of perceptual judgments. Working through the example of phone vibrations, we can see how this theory explains why they are a common and unavoidable part of healthy mental function. When your phone is in your pocket, the world is in one of two possible states: the phone is either ringing or not. You also have two possible states of mind: the judgment that the phone is ringing, or the judgment that it isn't. Obviously you'd like to match these states in the correct way. True vibrations should go with "it's ringing", and no vibrations should go with "it's not ringing". Signal detection theory calls these faithful matches a "hit" and a "correct rejection" But there are two other possible combinations: you could mismatch true vibrations with "it's not ringing" (a "miss"); or mismatch the absence of vibrations with "it's ringing" (a "false alarm"). This second kind of mismatch is what's going on when you imagine a phantom phone vibration. What does that mean in terms of your phone? We can assume that people like to notice when their phone is ringing, and that most people hate missing a call. This means their perceptual systems have adjusted their bias to a level that makes misses unlikely. The unavoidable cost is a raised likelihood of false alarms of phantom phone vibrations. The trade-off between false alarms and misses also explains why we all have to put up with fire alarms going off when there isn't a fire. It isn't that the alarms are badly designed, but rather that they are very sensible to smoke and heat and biased to avoid missing a real fire at all costs. The outcome is a rise in the number of false alarms. These are inconvenient, but nowhere near as inconvenient as burning to death in your bed or office. The alarms are designed to err on the side of caution.
Question: The writer tries to explain phantom phone vibrations_.
Options: (A) by analyzing some facts (B) by giving some examples (C) from the angle of biology (D) from the angle of psychology

A: D

Q: Article: Choosing the Right Resolution Millions of Americans began 2014 with the same resolution they started 2013 with, a goal of losing weight. However, setting weight loss as a goal is a mistake. To reach our goal of losing weight --- the output, we need to control what we eat --- the input ( ). That is, we tend to care about the output but not to control the input. This is a bad way to construce goals. The alternative is to focus your resolution on the input. Instead of resolving to lose weight, try an actionable resolution: "I'll stop having desert for lunch," or "I'll walk every day for 20 minutes." Creating a goal that focuses on a well-specified input will likely be more effective than concentrating on the outcome. Recently a new science behind incentives , including in education, has been discussed. For example, researcher Roland Fryer wanted to see what works best in motivating children to do better in school. In some cases, he gave students incentives based on input, like reading certain books, while in others, the incentives were based on output, like results on exams. His main finding was that incentives increased achievement when based on input but had no effect on output. Fryer's conclusion was that the intensives for inputs might be more effective because do not knoe how to do better on exam, aside from general rules like "study harder." Reading certain books, on the other hand, is a well-set task over which they have much more control. As long as you have direct control over your goal, you have a much higher chance of success. And it's easier to start again if you fail, because you know exactly what you need to do. If you want to cut down on your spending, a good goal would be making morning coffee at home instead of going to a cafe, for example. This is a well-specified action-based goal for which you can measure your success easily. Spending less money isn't a goal because it's too general. Similarly, if you want to spend more time with your family, don't stop with this general wish. Think bout an actionable habit that you could adopt and stick to, like a family movie night every Wednesday. In the long run, these new goals could become a habit.
