Read the following article and select the best answer. Article: When companies do business overseas, they come in contact with people from different cultures.These individuals often speak a different language and have their own particular custom and manners.These differences can create problems. For example, in France, business meetings begin promptly at the designated time and everyone is expected to be there.Foreign business people who are late are often left outside to cool their heels as a means of letting them know the importance of promptness.Unless one is aware of such expected behaviors, he may end up insulting the people with whom he hopes to establish trade relations. A second traditional problem is that of monetary conversions .For example, if a business deal is conducted with Russia, payment may be made in rubles.Of course, this currency is of little value to the American firm.It is, therefore, necessary to convert the foreign currency to American dollars.How much are these Russian rubles worth in terms of dollars? This conversion rate is determined by every market, where the currencies of countries are bought and sold.Thus there is an established rate.although it will often change from day to day.For example, the ruble may be worth 0.75 on Monday and 0.72 on Tuesday because of an announced wheat shortage in Russia.In addition, there is the dilemma associated with converting at 0.72.Some financial institutions may be unwilling to pay this price, feeling that the ruble will sink much lower over the next week.As a result, conversion may finally come at 0.69.These "losses" must be accepted by the company as one of the costs of doing business overseas. A third unique problem is trade barriers.For one reason or another, all countries impose trade barriers on certain goods crossing their borders.Some trade barriers are directly related to exports.For example, the United States permits strategic military material to be shipped abroad only after government permission has been obtained.Most trade barriers, however, are designed to restrict... Question: According to the passage, conversion rates _ . - are always changing - are determined by financial institutions - are agreed upon by two trading countries - vary from day to day
**Answer**
vary from day to day

Read the following article and select the best answer. Article: Being physically active three times a week reduces the odds of being depressed by about 16%, according to new UCL research carried out as part of the Public Health Research Center. The study, published in JAMA Psychiatry, found a two-way relationship between depression and physical activity. People who increased their weekly activity reported fewer depressive symptoms but those with more depressive symptoms were less active, particularly at younger ages. Researchers followed 11,135 people born in 1958 up until the age of 50, recording depressive symptoms and levels of physical activity at regular intervals in adulthood. They found that each additional activity period per week reduced odds of depression by 6%. In England 19% of men and 26% of women are currently classed as "inactive", and this study suggests that activity could significantly improve their mental as well as physical health. "Assuming the association is causal, physical activity has a protective effect against depression. If an adult between their twenties and forties who isn't physically active became active 3 times per week, they would reduce their risks of depression by about 16%." says Dr Snehal of the UCL Institute of Child Health, lead author of the study. Professor Mark, Director of the Public Health Research Center, said, "Many people are already aware of the benefits of physical activity on their general health, but now we are seeing more evidence that suggest it also has a positive effect on a person's mental well-being. The latest research highlights just how important it is to ensure that people are working and living in environments that allow them to be both physically active and mentally healthy." Question: The author shows his view mainly by _ . - doing research - comparing and contrasting - trying on himself - discussing and summarizing
**Answer**
comparing and contrasting

Read the following article and select the best answer. Article: Several recent studies have found that being randomly assigned to a roommate of another race can lead to increased tolerance but also to a greater likelihood of conflict. Recent reports found that lodging with a student of a different race may decrease prejudice and compel students to engage in more ethnically diverse friendships. An Ohio State University study also found that black students living with a white roommate saw higher academic success throughout their college careers. Researchers believe this may be caused by social pressure. In a New York Times article, Sam Boakye - the only black student on his freshman year floor -said that "if you're surrounded by whites, you have something to prove." Researchers also observed problems resulting from pairing interracial students in residences. According to two recent studies, randomly assigned roommates of different races are more likely to experience conflicts so strained that one roommate will move out. An Indiana University study found that interracial roommates were three times as likely as two white roommates to no longer live together by the end of the semester. Grace Kao, a professor at Penn said she was not surprised by the findings. "This may be the first time that some of these students have interacted, and lived, with someone of a different race," she said. At Penn, students are not asked to indicate race when applying for housing. "One of the great things about freshman housing is that, with some exceptions, the process throws you together randomly," said Undergraduate Assembly chairman Alec Webley. "This is the definition of integration." "I've experienced roommate conflicts between interracial students that have both broken down stereotypes and reinforced stereotypes," said one Penn resident advisor (RA). The RA of two years added that while some conflicts "provided more multicultural acceptance and melding ," there were also "jarring cultural confrontations." The RA said that these conflicts have also occurred among roommates of the same...
