Read the following article and answer the question. Article: Telling fewer lies benefits people physically and mentally. Anita Kelly, study author and professor of psychology at the University of Notre Dame, recruited 110 adults for her study. She divided them into two groups and asked one group to stop lying for 10 weeks. Lies included big ones and tiny ones--any false statement--but participants were still allowed to leave out the truth, keep secrets and avoid questions they didn't want to answer, etc. The other group wasn't given any special instructions about lying. It turns out that both groups reduced their lying, but those who were specifically told to tell the truth improved their health more. "We found that the participants could purposefully and dramatically reduce their everyday lies, and that in turn was associated with significantly improved health," said Kelly. When participants in the no-lie group told three fewer white lies than they did in other weeks, they experienced, on average, fewer mental-health complaints and physical complaints. They were less likely to feel tense or sad and also experienced fewer sore throats and headaches. They also reported that personal relationships improved. Additionally, participants found themselves being honest about their daily accomplishments, and they stopped making up excuses for being late or failing to complete a task, for example. "It's certainly a worthy goal to have people be more honest and interact with others in a more honest way," says psychologist Robert Feldman. "That would be beneficial. I'm a little doubtful that it makes us all healthier, but it may make us healthier in a psychological way." Question: The participants of the two groups _ . Answer:
OPTIONS:
- told as many lies as before
- were almost equally healthy
- tended to lie less about their activities
- experienced tenser personal relationships

Answer: tended to lie less about their activities

Read the following article and answer the question. Article: Each year millions of babies are born too soon and too small. Premature or preterm births are defined as births at less than thirty-seven weeks. Prematurity is the leading cause of death in newborn babies. More than one-fourth of the four million newborns who die each year around the world were born too early. Preterm babies that survive can suffer a lifetime of serious health conditions. The examples include cerebral palsy, blindness, hearing problems and learning disabilities. Families and communities face emotional, physical and financial costs. Christopher Howson is the vice president for global programs at the March of Dimes, a nonprofit group. His group and the World Health Organization recently published a report called "The Global and Regional Toll of Preterm Birth." CHRISTOPHER HOWSON: "Frankly the crisis of preterm birth is under-recognized, undercounted, undervalued and under-funded. I mean, this report shows that thirteen million babies are born every year preterm, and that over a million of those babies die as a result of being born too early." And these are just estimates; the true numbers could be even higher. More than eighty-five percent of preterm births happen in Africa and Asia. Africa has the highest rate, with about four million cases each year. Chris Howson says many of the causes of preterm births are related to poverty and weak health-care systems. CHRISTOPHER HOWSON: "For example, the poor overall health and nutritional status of women. A high burden of infectious diseases. Lack of provision of family planning - allowing a woman to decide when to start and end having children and how to space her children. And also the lack of good prenatal care programs that might identify problems early on in pregnancy." Preterm births are a problem not just in the developing world. The combined rate in the United States and Canada is the second highest in the world. Preterm birth rates in the United States have increased thirty-six percent in the last twenty-five... Question: Which of the following is a true statement according to the passage? Answer:
OPTIONS:
- Preterm birth rates in developing countries are dropping and they are increasing in some developed countries like the US and Canada.
- The increase in pregnancies among women over age thirty-five and the increase in the use of reproductive therapies result in the increase of preterm birth rates.
- Fortunately, many people have already realized the seriousness of the problem of preterm births.
- Preterm births must be a problem for only poor areas because of poverty.

Answer: The increase in pregnancies among women over age thirty-five and the increase in the use of reproductive therapies result in the increase of preterm birth rates.

Read the following article and answer the question. Article: Across the planet there are millions of people who engage in some type of meditation, the practice of concentrating and clearing the mind to bring the body into a state of peace, at least a semi-regular basis. For some, particularly among practitioners of Eastern religions such as Buddhism and Hinduism, this is _ of their religious practice. For others, particularly in Western cultures, meditation tends to be a response to stress. With the world economy approaching meltdown and people worried about their job or their ability to keep their home, it's a way for people to attain a state of peace of mind and well-being. For those interested in taking up the practice, instruction in meditation for beginners can be found in literally thousands of sources. One of the most popular styles of mediation in the West, with classes offered in most major cities, is called Transcendental Meditation. TM, as it is known among its practitioners, first came to worldwide attention when the Beatles began practicing it in 1967. For direct, guided, personal instruction in meditation for the beginner, TM may be the hallmark. Part of the confusion about how to practice meditation effectively is due to the fact that there are literally hundreds of techniques championed by various groups and individuals. As a general principle, it might be said that all meditation techniques seek to have the practitioner attain a state of consciousness that is different to our ordinary state of awareness. They attempt to train people to clear their minds and achieve a sense of inner peace. It sounds simple enough, but of the huge number of people experiment with meditation, very few are able to maintain its practice over the long haul. In most cases, this is due to frustration over the inability to experience any dramatic, instantly recognizable effects. This is quite a sad state of affairs, that so few these days are willing or equipped to persist in something that doesn't provide immediate life-changing results. It reflects a culture in which demands... Question: What can we infer about meditation from the passage? Answer:

- It is practiced by many famous artists.
- Its benefits are not immediately obvious.
- Most people find it a very good way to relax.
