Even more than mountainside slides of mud or snow, naturally occurring forest fires promote the survival of aspen trees. Aspens' need for fire may seem illogical since aspens are particularly vulnerable to fires; whereas the bark of most trees consists of dead cells, the aspen's bark is a living, functioning tissue that—along with the rest of the tree—succumbs quickly to fire.

The explanation is that each aspen, while appearing to exist separately as a single tree, is in fact only the stem or shoot of a far larger organism. A group of thousands of aspens can actually constitute a single organism, called a clone, that shares an interconnected root system and a unique set of genes. Thus, when one aspen—a single stem—dies, the entire clone is affected. While alive, a stem sends hormones into the root system to suppress formation of further stems. But when the stem dies, its hormone signal also ceases. If a clone loses many stems simultaneously, the resulting hormonal imbalance triggers a huge increase in new, rapidly growing shoots that can outnumber the ones destroyed. An aspen grove needs to experience fire or some other disturbance regularly, or it will fail to regenerate and spread. Instead, coniferous trees will invade the aspen grove's borders and increasingly block out sunlight needed by the aspens.

C1.The primary purpose of the passage is to explain the (A) qualities that make a particular organism unique

(B) evolutionary change undergone by a particular organism

2

(C) reasons that a phenomenon benefits a particular organism (D) way in which two particular organisms compete for a resource

(E) means by which a particular organism has been able to survive in a barren region

C2. It can be inferred from the passage that when aspen groves experience a \

(A) leads to a hormonal imbalance within an aspen clone (B) provides soil conditions that are favorable for new shoots (C) thins out aspen groves that have become overly dense (D) suppresses the formation of too many new aspen stems

(E) protects aspen groves by primarily destroying coniferous trees rather than aspens

B3. The author of the passage refers to \emphasize the

(A) vulnerability of aspens to damage from fire when compared to other trees (B) rapidity with which trees other than aspens succumb to destruction by fire

(C)relatively great degree of difficulty with which aspens catch on fire when compared to other trees

(D) difference in appearance between the bark of aspens and that of other trees (E) benefits of fire to the survival of various types of trees

D4.According to the passage, which of the following would occur if an aspen grove failed to regenerate periodically?

(A) Individual aspens would cease to produce hormones

(B) Individual aspens would grow outward instead of upward. (C) The root system of the grove's clone would die. (D) The grove would lose its access to sunlight

(E) Soil conditions in the grove would become unfavorable for the growth of aspens.

d1.On Pacific islands, a newly arrived gecko species, the house gecko, is displacing the previously established mourning gecko in urban areas, but populations of the two species are more stable in rural areas far from human settlement. The house gecko does not attack the mourning gecko, but in areas where insects congregate it prevents the mourning gecko from feeding on them.

Which of the following contributes most to an explanation of the difference between gecko populations in urban and rural areas?

(A) In urban areas, geckos are valued because they eat so many insects. (B) Geckos defend territories against other members of the same species. (C) House geckos that arrive on islands are carried there in boats and planes.

(D) In places where there are lighted buildings, insects tend to gather around the light.

3

(E) Mourning geckos are all females and reproduce asexually, but house geckos reproduce sexually.

E2.In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent. In contrast, in the year prior to the tax increase, sales had fallen one percent. The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.

Which of the following, if true, would most strengthen the argument above?

(A) During the second year after the tax increase, cigarette sales increased by a significant amount.

(B) The information available to consumers on the health risks of smoking remained largely unchanged in the period before and after the tax increase.

(C) Most consumers were unaware that the tax on cigarettes was going to increase. (D) During the year following the cigarette tax increase, many consumers had less income, in inflation-adjusted dollars, than they had had in the previous year.

(E) During the year after the tax increase, there was a greater variety of cigarettes on the market than there had been during the previous year.

C3.In the country of Veltria, the past two years’ broad economic recession has included a business downturn in the clothing trade, where sales are down by about 7 percent as compared to two years ago. Clothing wholesalers have found, however, that the proportion of credit extended to retailers that was paid off on time fell sharply in the ?rst year of the recession but returned to its prerecession level in the second year.

Which of the following, if true, most helps to explain the change between the ?rst and the second year of the recession in the proportion of credit not paid off on time?

(A) The total amount of credit extended to retailers by clothing wholesalers increased between the ?rst year of the recession and the second year.

(B) Between the ?rst and second years of the recession, clothing retailers in Veltria saw many of their costs, rent and utilities in particular, increase.

(C) Of the considerable number of clothing retailers in Veltria who were having ?nancial dif?culties before the start of the recession, virtually all were forced to go out of business during its ?rst year.

(D) Clothing retailers in Veltria attempted to stimulate sales in the second year of the recession by discounting merchandise.

(E) Relatively recession-proof segments of the clothing trade, such as work clothes, did not suffer any decrease in sales during the ?rst year of the recession.

D4.The higher the level of certain vitamins and minerals in the bloodstream, the better a person's lung function, as measured by the amount of air the person can expel in one second. The lung function of smokers is significantly worse, on average, than that of nonsmokers. Clearly, therefore, one way for smokers to improve their lung function is for them to increase their intake of foods that are rich in these helpful vitamins and minerals.

Which of the following is an assumption on which this argument depends?

(A) Smokers are less likely than nonsmokers to have diets that are rich in vitamins and minerals.

(B) The lung function of smokers whose diets are rich in those vitamins and minerals is generally better than that of nonsmokers with comparable diets.

(C) People whose diets are deficient in those vitamins and minerals do not typically have other health problems in addition to diminished lung function.

(D) Stopping smoking will not typically improve lung function more than any diet changes can.

(E) Smoking does not introduce into the body chemicals that prevent the helpful vitamins and minerals from entering the bloodstream.
