Passage One
A new study reports the common drug aspirin greatly reduces life threatening problems after an operation to replace blocked blood vessels to the heart. More than 800,000 people around the world have this heart surgery each year. ____1____ People usually take aspirin to control pain and reduce high body temperature. Doctors also advise some people to take aspirin to help prevent heart attacks. About 10% to15% of these heart operations end in death or damage to the heart or other organs. ____2____ The doctors said the chance of death for patients who took aspirin would fall by 67%. They claimed this was true if the aspirin was given within 48 hours of the operation. The doctors believe aspirin helps heart surgery patients because it can prevent blood from thickening and blood vessels from being blocked. ____3____

Passage Two
Were you the first or the last child in your family? Or were you a middle or only child? Some people think it matters where you were born in your family. But there are different ideas about what birth order means. ____4____ They are very likely to be successful. The reason for this is simple. Parents have a lot of time for their first child; they give him or her a lot of attention. So this child is very likely to do well. An only child will succeed for the same reason. What happens to the other children in the family? Middle children don't get so much attention, so they don't feel that important. ____5____ The youngest child, though, often gets special treatment. He or she is the baby. Often this child grows up to be funny and charming. Do you believe these ideas about birth order too? A recent study saw things quite differently. The study found that first children believed in family rules. They didn't take many chances in their lives. They usually followed orders. ____6____ They went out and followed their own ideas. They took chances and they often did better in life.
The doctors who carried out the study say giving aspirin to patients soon after the operation could save thousands of lives. The new study shows that even a small amount of aspirin reduced such threats. However, the doctors warned that people who have stomach bleeding or other bad reactions from aspirin should not take it after heart surgery. Some people say that oldest children are smart and strong-willed. If a family has many children, the middle one sometimes gets lost in the crowd. Rules didn't mean as much to later children in the family.
