1. When feeding, aquatic birds known as phalaropes often spin rapidly on the water’s surface, pecking for food during each revolution. To execute these spins, phalaropes kick one leg harder than the other. This action creates upwelling currents. Because plankton on which phalaropes feed typically occurs in greater quantities well below the surface, it is hypothesized that by spinning phalaropes gain access to food that would otherwise be beyond their reach.

Which of the following, if true, most strongly supports the hypothesis?

A. Phalaropes rarely feed while on land.
B. A given phalarope spins exclusively either to the right or to the left.
C. Phalaropes sometimes spin when they are not feeding.
D. Different phalaropes spin at somewhat different rates.
E. Phalaropes do not usually spin when food is abundant at the surface.

2. Which of the following most logically completes the passage?

Concerned about the financial well-being of its elderly citizens, the government of Runagia decided two years ago to increase by 20 percent the government-provided pension paid to all Runagians over 65. Inflation in the intervening period has been negligible, and the increase has been duly received by all eligible Runagians. Nevertheless, many of them are no better off financially than they were before the increase, in large part because __________.

A. they rely entirely on the government pension for their income
B. Runagian banks are so inefficient that it can take up to three weeks to cash a pension check
C. they buy goods whose prices tend to rise especially fast in times of inflation
D. the pension was increased when the number of elderly Runagians below the poverty level reached an all-time high
E. in Runagia children typically supplement the income of elderly parents, but only by enough to provide them with a comfortable living
第二题的正确答案E，但是他们的子女补贴父母的钱和他们没有benefit from the pension有一毛钱关系啊？
