1. A society’s infant mortality rate is an accepted indicator of that society’s general health status. Even though in some localities in the United States the rate is higher than in many developing countries. In the United States, overall the rate has been steadily declining. This declines does not necessarily indicate, however, that babies in the United States are now, on the average, healthier at birth than they were in the past.
Which one of the following reasons, if true, most strongly supports the claim made above about the implications of the decline?
A. The figure for infant mortality is compiled as an overall rate and thus masks deficiencies in particular localities.
B. Low birth weight is a contributing factor in more than half of the infant deaths in the United States.
C. The United States has been developing and his achieved extremely sophisticated technology for saving premature and low-birth-weight babies, most of whom require extended hospital stays.
D. In eleven states of the United States, the infant mortality rate declined last year.
E. Babies who do not receive adequate attention from a caregiver fail to thrive and so they gain weight slowly.
as the passage suggests, the decline, in the author's opinion, does not indicate that the babies are healthier than b4.so ,in support of this conclusion ,we must show that though the babies are not healthier but they survive.
A is skeptical about the accuracy of the statistics .
B gives us a piece of irrelevant information.
D is also irrelevant. So is e.
C tells us why unhealthy babies can survive and the death rate declines.
C is the right answer.
2. The public is well aware that high blood cholesterol levels raise the risk of stroke caused by blood clots, but a recent report concludes that people with low blood cholesterol levels are at increased risk of the other lethal type of stroke---cerebral hemorrhage, caused when a brain artery busts. The report suggests that because blood cholesterol plays a vita role in maintaining cell membranes, low blood cholesterol weakens artery walls, making them prone to rupture. The conclusion thus supports a long-standing contention by Japanese researchers that Western diets better protect against cerebral hemorrhage than do non-Western diets.
The argument is based on which one of the following assumption?
A. Western diets are healthier than non-Western diets.
B. Western diets result in higher blood cholesterol levels than do non-Western diets.
C. High blood cholesterol levels preclude the weakening of artery walls.
D. Cerebral hemorrhages are more dangerous than strokes caused by blood clots.
E. People who have low blood pressure are at increased risk of cerebral hemorrhage.
The passage provides us with information of the relationship between stroke and the level of blood cholesterol. but the conclusion is about the relationship between diet and hemorrhage. so there is a gap here. We must find the bridge. Only B, the right answer, closes the gap.
