Despite the fact that the seeds of certain tropical trees fall mostly around the parent tree, the seeds that land farther from the parent trees of these species have the greatest chance of germinating. One hypothesis is that the effect is caused by rodents eating a larger number of seeds beside the parent tree than seeds in places farther away, but studies have shown that this is not so.

Which of the following, If true, would most help explain the effect described above?

A. Tree sprouts from seeds must compete for moisture and nutrients with some of the plant life in their immediate vicinity.

B. Some tropical trees have winged seeds that tend to prevent them landing beside the parent trees.

C. Certain tropical tree species are preferentially colonized by some types of mammals.

D. Soil microbes that prey on seeds and other biological material from trees of the tropical species in question tend to be densest near those trees.

E. Some plants emit chemicals that are harmful to nearby seeds of other species.

It is known from cave paintings and other evidence that the hunting people occupying the Bax Cave area in Country X tens of thousands of years ago repeatedly set fire to the surrounding area. Archaeologists hypothesize that because the fires caused later plant growth on the land, the hunters set the fires in order to attract herbivorous prey species. Such actions, they claim, are evidence for the mental capacity to delay gratification for weeks, months, or even years.

Which of the following would it be most useful to determine in evaluating the archaeologists' claim?

A. Whether the Bax Cave area is susceptible to fires caused by lightning strikes

B. Whether remains can be found of hunting tools from tens of thousands of years ago in or near the Bax Cave

C. Whether people occupying the Bax Cave tens of thousands of years ago consumed plants adapted to fire ecologies

D. Whether in the immediate aftermath of fires in the Bax Cave area, animals sought by hunters came to seek prey driven out of dens or other shelters

E. Whether the mental capacity to delay gratification for weeks, months, or even years was exhibited by contemporaries of the people occupying the Bax Cave tens of thousands of years ago
