Question 4 Single choice

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.

Question 7 Single choice

The passage most strongly suggests that the author agrees with which of the following?

A
There was not significantly less coverage by trees and other vegetation in Victoria after European immigrant settlement than before it.
B
Average groundwater levels in Victoria probably increased after European immigrant settlement.
C
Dahlhaus's examination of early cartographic evidence convinced him that European immigrant settlement was a significant factor contributing to soil salinity in Victoria.
D
The impact of European immigrant settlement on the environment in Victoria does not explain soil salinity there.
E
The main source of soil salinity in Victoria has been wind and rain transporting salt from the sea.

Show answer and explanation

Correct answer: D

Explanation

Explanation: Soil salinization--the process by which soil acquires excess soluble salt, adversely affecting pasture or crop growth--is regarded as Australia's most serious environmental problem. Cope, whose 1958

investigation is considered the earliest survey of salt-affected areas in Victoria, hypothesized that surplus rainwater mobilized soluble salt stored in the permeable layer of soil, causing it to accumulate above an impermeable layer and then discharge downslope or onto a valley floor. In the late 1970s, however, Jenkin identified saline water underground as the main and immediate (though not ultimate) source of the salt, and hypothesized that the spread of salinity resulted from a rise in that groundwater. He attributed the rise to a decrease in coverage by water-absorbing trees and other vegetation at some ill-defined point in Australia's post-settlement history. However, more-recent research suggests there was no rise in post- settlement groundwater levels. Furthermore, soil salinity probably antedated European settlement: early
cartographic evidence indicates that some streams were saline when Europeans arrived. Dahlhaus suggests that salt accumulation resulted from marine incursions several million years ago, when parts of Victoria may have been submerged--as well as from transport of salt from the sea by wind and rain.
Dahlhaus also notes that various minerals dissolved in groundwater by weathering may have produced salt.

Question 9 Single choice

Which of the following statements concerning the valence model and the approach-withdrawal model most accurately reflects information provided in the passage?

A
Each of the two models implicates both hemispheres of the human brain in the processing of emotion.
B
Both models suggest that cognitive information is processed by only one brain hemisphere in humans.
C
Each of the two models explains how emotional information affects the processing of cognitive information in the human brain.
D
Both models seek primarily to describe how emotion is expressed in behavior.
E
The assumptions of both models concerning the processing of visuospatial information are identical with those made by Karev.

Show answer and explanation

Correct answer: A

Explanation

Explanation: Despite overall physiological bilateral symmetry, many species exhibit lateralized biases, i.e., preferences for right-or left-oriented behavior. When approaching prey, for example, some predator

species favor their right eye; some prey species respond more quickly when their left eye detects a predator. Similar behavioral asymmetries occur in humans. Most notable is right-and lefthandedness; less
notable is the tendency to turn right when entering a room. Paul Farnsworth found that more successful students tended to choose seats near the front, a little to the right. He argued that external factors such as teacher location might have affected this lateral bias. But it is now known that processing differences between the two brain hemispheres can also contribute to behavioral asymmetries.
George Karev found that when presented with a movie theater seating diagram, right-handed people were more likely than left-handed people to choose a seat on the right, facing front. But he hypothesized that, since the right hemisphere processes visuospatial and emotional information, the people who chose right-side seats did so because that would put the screen in their left visual field, optimizing information flow to the right hemisphere. Although the right hemisphere is thought to be dominant in processing emotion, some evidence suggests that the left hemisphere plays a role. The valence model proposes that the left and right hemispheres process positive and negative emotion respectively, while the approach-withdrawal model posits that the left hemisphere processes emotion expressed in approach behavior and the right hemisphere processes emotion expressed in withdrawal behavior. Victoria Harms and colleagues suggested that since a paper seating plan was used in the theater-seating studies by Karev and others, the exhibited preference might be due simply to handedness: people choose the same side of the paper as their favored hand. Consequently, the Harms research was designed to study choices in an actual movie theater. Also, hoping to distinguish between various explanations, they studied seating choices for comedies (presumed to contain Positive emotional content), dramas (presumed to contain negative emotional content), and documentaries (presumed to have balanced emotional content).
