Question 100

Conservationist: The population of a certain wildflower is so small that the species is headed for extinction. However, this wildflower can cross-pollinate with a closely related domesticated daisy, producing viable seeds. Such cross-pollination could result in a significant population of wildflower-daisy hybrids. The daisy should therefore be introduced into the wildflower's range, since although the hybrid would differ markedly from the wildflower, hybridization is the only means of preventing total loss of the wildflower in its range.

Which one of the following is an assumption on which the conservationist's reasoning depends?

Select an option, then click Submit answer.

  • The wildflower currently reproduces only by forming seeds.

  • The domesticated daisy was bred from wild plants that once grew in the wildflower's range.

  • Increasing the population of the wildflower will also expand its range.

  • Wildflower-daisy hybrids will be able to reproduce.

  • The domesticated daisy will cross-pollinate with any daisy like plant.

Question 101

Because of increases in the price of oil and because of government policies promoting energy conservation, the use of oil to heat homes fell by 40 percent from 1970 to the present, and many homeowners switched to natural gas for heating. Because switching to natural gas involved investing in equipment, a significant switch back to oil in the near future is unlikely.

The prediction that ends the passage would be most seriously called into question if it were true that in the last few years

Select an option, then click Submit answer.

  • the price of natural gas to heat homes has remained constant, while the cost of equipment to heat homes with natural gas has fallen sharply

  • the price of home heating oil has remained constant, while the cost of equipment to heat homes with natural gas has risen sharply

  • the cost of equipment to heat homes with natural gas has fallen sharply, while the price of home heating oil has fallen to 1970 levels

  • the cost of equipment to heat homes with oil has fallen sharply, while the price of heating with oil has fallen below the price of heating with natural gas

  • the use of oil to heat homes has continued to decline, while the price of heating oil has fallen to 1970 levels

Question 102

Parents should not necessarily raise their children in the ways experts recommend, even if some of those experts are themselves parents. After all, parents are the ones who directly experience which methods are successful in raising their own children.

Which one of the following most closely conforms to the principle that the passage above illustrates?

Select an option, then click Submit answer.

  • Although music theory is intrinsically interesting and may be helpful to certain musicians, it does not distinguish good music from bad: that is a matter of taste and not of theory.

  • One need not pay much attention to the advice of automotive experts when buying a car if those experts are not interested in the mundane factors that concern the average consumer.

  • In deciding the best way to proceed, a climber familiar with a mountain might do well to ignore the advice of mountain climbing experts unfamiliar with that mountain.

  • A typical farmer is less likely to know what types of soil are most productive than is someone with an advanced degree in agricultural science.

  • Unlike society, one's own conscience speaks with a single voice; it is better to follow the advice of one's own conscience than the advice of society.
