I'm taking a test and have to guess the right answer to the question after the article. Article: People who are worried about bad breath often reach for a toothbrush or a gun. But in the future, personal breath monitoring may include far more than fresh breath. In face, breath is so rich in chemical compounds that fully understanding it has proved challenging. Each breath contains gases like carbon dioxide, the volatile remains of recent snacks, medicines and even compounds taken in from things like carpeting or various kinds of air pollution. But breath detectors can sort out these substances with increasing sensitivity . Scientists are building electronic sniffers that examine the exhaled air for signs of cancer, asthma , and other diseases. "There are clear signatures in the breath for liver disease, kidney disease and heart disease. Breath is a rich mixture that can reflect out state of health and disease." said Dr. Raed Dweik, director of the Cleveland Clinic, adding "Breath analysis is the future of medical testing." He and his partners are testing a desktop system called BreathLink for use in rapid identification of diseases. The system is designed to work wherever there is an Internet connection. To use BreathLink, a person breathes into a long tube, and a breath sample is collected and analyzed within the system. Then it can detail chemical concentrations of the breath in graphics. Dr. Raed Dweik said, "If you examine patients of asthma, you will find they have higher levels of nitric oxide in their exhaled air. It reflects their abnormal symptoms in the lungs." His tests have reached 85 percent accuracy so far in spotting people with some illness. But some trained dogs, he pointed out, can sniff out cancer with 99 percent accuracy--although without the ability to identify particular compounds the way some detectors can. "We are getting better and better," he said. "But whether we will ever approach the accuracy of the dog--we don't know." Question: What's the author's attitude towards the future of breath detectors? Options: A: Indifferent B: Positive C: Doubtful. D: Critical.

I'm taking a test and have to guess the right answer to the question after the article. Article: Americans plan parties for many reasons. As in other cultures, many Americans attend parties for weddings and religious or national holidays. But some parties are especially American. For example, a group of neighbors may gather on their street to eat food, play music and visit with one another. This is called a block party. A woman might invite a group of women to a party called a baby shower for a friend who is about to give birth. Guests bring presents for the new baby. Americans also attend tailgate parties. A tailgate is the back end of a truck or other vehicle that opens down. The tailgate parties are a big part of sports culture in the United States. Friends bring food and drink to a sports event. They eat together in the parking area of the sports stadium. Birthday parties are also very popular. Many parents organize a party for their child around a theme. Birthday parties usually include gifts and a birthday cake with candles. In many parts of the United States, cupcakes have become a popular replacement for cakes. Birthday parties can be low cost or very costly. Some parents take their children's birthday parties very seriously, even when the child is too young to fully understand the celebration. One group of parents started a website called Birthdays Without Pressure. They decided that some parents were under too much social pressure to plan costly parties for their children. The group sees this movement as an example of America's culture of "too much stuff". The group's website gives suggestions on how to keep birthday celebrations simple, meaningful and fun without spending a lot of money. Their advice may be very helpful during this period of economic recession . Question: The purpose of Birthdays Without Pressure is to advise people to _ . Options: A: relieve people's pressure B: have meaningful birthday parties with low cost C: make birthday parties meaningful and costly D: spread America's culture

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: One evening I was on my daily evening return from London to my home. I had got into the habit of sitting in the last carriage at the platform, so I could get off near to the station exit at my end. One evening before getting off the train, I found a purse. I opened the purse and thought this must be my lucky day, for the purse contained some PS80 in cash. Looking further into the purse, I found credit cards, and house keys and a name and address. My first thought when seeing the cash was to pocket it, and throw the other contents away. Now I am not a basically dishonest person, but had developed a hardened attitude over the years that most people were dishonest in some way, and my own personal experience had been that whenever I lost anything of value, that was the last I ever saw of it. And since I was a construction worker at that time, I had been the victim of a great deal of stealing during my working life. Almost as I read the name and address, I had a picture of that woman being struck with terror, when she realized she had lost her purse, and could not get into her home, had no money, and, would have thoughts of someone spending on her credit cards, not to mention the trouble of canceling all the cards. In that same moment I decided to hand the purse over to the train guard. So I told him I would like to see it returned to its rightful owner. He told me would be sent to the lost property office. I arrived at my station and started to walk the five minute journey to my home all the while feeling very pleased with myself that I was going to bring a great deal of happiness to someone I did not know. Question: The author liked to sit in the last carriage because _ . Options: A: sitting in the last carriage was safer B: he was always almost late for his train C: he could get out of the station sooner after getting off D: he likes chatting with the train guards there
A: C
*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: Researchers in London and Bristol have found that men are particularly likely to yield to depression if their partners are also depressed. The finding highlights the importance of paying attention to the partners of depressed mothers, as young children themselves are vulnerable to social problems if both parents are depressed. Researchers in London and at the University of Bristol launched their study to investigate whether family structure affects the likelihood of depression in men around the time their child is born. They looked at men from traditional families, men with children from a previous relationship, men whose partners had children by a former partner, and men who were not living with their partners. All 7,108 participants filled out a questionnaire on depression, and answered questions about their age, education level and employment status. Details about the quality of their relationships with their partners, networks of friends and previous life events were also recorded. About 3.5 percent of the men and 13 percent of their partners suffered depression around the time their child was born. While men in stepfamilies or who were not living with their partners were twice as likely to get depressed as those in traditional families, this could be explained by other factors that are more common in nontraditional families, such as poor education and relationship conflicts. Even allowing for all these factors, however, the partners of women who were suffering from prenatal depression were significantly more likely to become depressed themselves, the researchers report in an American journal. Ten percent of women who were depressed had depressed partners. For the healthy women, the figure was only 2.6 percent. Previous research suggests that families with two depressed parents may need special attention. A researcher in Atlanta has found that primary school children with two troubled parents have difficulty relating to their peers. "It's extremely important to look at the whole family." she says. Question: According to the passage, which of the following statements is NOT true? Options: A: Ten percent of women who were depressed had depressed partners. B: 2.6 percent of healthy women were depressed. C: Special attention should be paid to families in which both the father and the mother were depressed. D: Primary school children whose parents were both depressed couldn't get along well withtheir peers.
