I'm taking a test and have to guess the right answer to the question after the article. Article: "Keep out or I'll chase you out! This is my property!" You hear this every spring. It is a long musical sound --- a bird song! Birds use their songs to communicate different messages to one another. People who study bird sounds are learning their meanings. Usually it is the male that sings. Early in spring he sings to say that he has picked out a piece of property. He sings to attract a female of his same kind. Together they will raise a family in his territory . He sings to tell all other birds of his kind to keep out. Each kind of bird has its own type of song. Cardinals sing something that sounds a little like "What cheer, cheer, cheer." Towhees sing, "Drink your tea." Most of the time, birds pay attention only to the songs of birds of their own kind. Cardinals answer cardinals, and song sparrows answer song sparrows. A cardinal knows that a song sparrow will not try to steal its mate. So you can see one reason why a cardinal may chase away another cardinal but will not bother a song sparrow. Most different kinds of birds eat different things. To find enough to eat, a bird needs a big piece of land to search in. Many kinds of birds have some ways of dividing up the land into territories. Song sparrows, cardinals ovenbirds, and white-throated sparrows are some of the birds that have territorial systems. Especially in early spring, birds work out the boundaries between their territories by singing "keep out" threats and by chasing and fighting each other. The birds continue singing to tell females that they have set up territories. Neighboring birds seem to agree that there are make believe fences between their pieces of property. Then they do not have to waste energy chasing each other instead of taking care of their young. Scientists guessed that some birds could recognize their neighbors by small differences in their songs. Two scientists who studied white-throated sparrows found that these birds can even tell the difference between songs of individual birds of their own kind. White-throated sparrows... Question: A cardinal may not keep a song sparrow out of its territory because _ . Options: A: they sing different songs B: they have separate territories C: it feels no threat from a song sparrow D: song sparrows are friendly to other birds

I'm taking a test and have to guess the right answer to the question after the article. Article: Older couples in a bad marriage -- particularly female spouses -- have a higher risk for heart disease than those in a good marriage, finds the first nationally representative study of its kind.The findings suggest the need for marriage counseling and programs aimed at promoting marital quality and well-being for couples into their 70s and 80s, said lead investigator Hui Liu, a Michigan State University sociologist. "Marriage counseling is focused largely on younger couples," said Liu. "But these results show that marital quality is just as important at older ages, even when the couple has been married 40 0r 50 years. " The study, funded by the National Institute of Aging, an arm of the National Institutes of Health,is published online in the Journal of Health and Social Behavior. Liu analyzed five years of data from about 1,200 married men and women who participated the National Social Life, Health and Aging Project. Respondents were aged 57-85 at the beginning of the study. The project included survey questions about marital quality, lab tests and self-reported measures of cardiovascular health such as heart attacks, strokes, hypertension and high levels of C-reactive protein in the blood. Liu set out to learn how marital quality is related to risk of heart disease over time, and whether this relationship varies by gender and/or age. Among her findings: Negative martial quality(eg.spouse criticizes, spouse is demanding) has a bigger effect on heart health than positive marital quality.In other words, a bad marriage is more harmful to your heart health than a good marriage.The effect of marital quality on cardiovascular risk becomes much stronger at older ages.Meanwhile,marital quality has a bigger effect on women's heart health than it does on men's, possibly because women tend to internalize negative feelings and thus are more likely to feel depressed and develop cardiovascular problems. Heart disease leads to a decline in marital quality for women, but not for men. It's common that wives are more... Question: According to the passage, who is most likefy to have a heart disease? Options: A: Marie, 40 years old,just got divorced. B: Bill, 66 years old, lives with his wife and grandchildren. C: Justin, 28 years old, got married recently. D: Sophia, 59 years old, often quarrels with her husband.
