1. Burger Land, a national fast-food chain, recently annouced a special promotion dramatically reducing the price of its most popular burger, the Big and Beefy. This development has provoked a strong response by the nation's nutritionists. Citing the extremely high levels of cholesterol in the Big and Beefy, they predict that the price reduction will have a negative impact on the health of our citizens.

The nutritionists' argument assumes which of the following?
A. Some consumers induced by the price reduction to purchase the Big and Beefy would otherwise have consumed food lower in cholesterol than the Big and Beefy.
B. Reducing fact consumption is the most important factor in improving one's diet.
C. Burger Land could not have increased sales of the Big and Beefy by reducing its cholesterol content and appealing to health-conscious consumers.
D. Other fast-food companies will not respond to Burger Land's announcement by reducing the price of their own high-cholesterol burgers.
E. Lost revenue due to the price reduction in the Big and Beefy will be offset by an increase in the number of burgers sold.

2. In country X, all citizens eligible to vote must do so or fact stiff fines. Because voting in Coutry X is mandatory, over 99 percent of the eligible voters voted in last election. Thus, the winner of the last election is truly the people's choice.
Which of the following identifies an assumption in the author's argument?
A. In country X, voters are allowed to vote for a candidate of their choice.
B. If country X did not make voting mandatory, few people would vote.

3. In the next four years, the number of doctors, nurses, and other health care workers will increase significantly worldwide. Even so, the average compensation received by such professionals will not decline but rather is likely to increase. This is due, at least partly, to the fact that the median age of the world's population will increase steadily in this same period of time.
The argument above depends logically upon which of the following assumptions?
A. The increase in the number of health care workers wil be responsible for the increase in the average life span.
B. The compensation of doctors and physical therapists who treat the elderly will increase more than that of other health care workers.
C. As a group, older people receive more attention from health care workers than do younger people.
D. Geriatrics, a branch of medicine focusing on the health problems of older people, is the most expensive element of American health care.
E. Increase in the median age of the population will occur in all regions of the world.
