Language acquisition has long been thought of as a process of imitation and reinforcement. Children learn to speak, in the popular view, by copying the utterances heard around them, and by having their response strengthened by the repetitions, corrections, and other reactions that adults provide. In recent years, it has become clear that this principle will not explain all the facts of language development. Children do imitate a great deal, especially in learning sounds and vocabulary; but little of their grammatical ability can be explained in this way. Two kinds of evidence are commonly used in support of this criticism–one based on the kind of language children produce, the other on what they do not produce. The first piece of evidence derives from the way children handle irregular grammatical patterns. When they encounter such irregular past-tense forms as went and took or such plural forms as mice and sheep, there is a stage when they replace these by forms based on the regular patterns of the language. They say such things as wented, taked, mices, mouses, and sheeps. Evidently, children assume that grammatical usage is regular, and try to work out for themselves what the forms 'ought' to be–a reasoning process known as analogy. They could not have learned these forms by a process of imitation. The other kind of evidence is based on the way children seem unable to imitate adult grammatical constructions exactly, even when invited to do so.

The idea that all mental functions are derived from the brain originated with Hippocrates, but it was largely neglected until the late 18th century, when Franz Gall attempted to link psychology and brain science. Gall took advantage of what was already known about the cerebral cortex. He was aware that it was bilaterally symmetrical and subdivided into four lobes. However, he found that these four lobes were, by themselves, inadequate to account for the forty-odd distinct psychological functions that psychologists had characterized by 1790. As a result he began to analyze the heads of hundreds of musicians, actors, etc., relating certain bony elevations or depressions under the scalp to the predominant talent or defects of their owners. Based on his skull palpation, Gall subdivided the cortex into roughly forty regions, each of which served as an organ for a specific mental function. While Gall's theory that all mental processes derive from the brain proved to be correct, his methods for localizing specific functions were deeply flawed because they were not based on what we would now consider valid evidence. Gall did not test his ideas empirically by performing autopsies on the brains of patients and correlating damage to specific regions with defects in mental attributes; he distrusted the diseased brain and did not think it could reveal anything about normal behavior. Instead, he developed the notion that as each mental function is used, the particular area of the brain responsible for that function becomes enlarged. Eventually, a given area may become so bulky that it pushes out against the skull and produces a bump on the head.

Diomedes Motors has just decided to start using Rapilux Tires on most models of its new cars. The tires cost the same as the previous tires, and the change in tires will not change the sticker price of any car, nor will it change the profit on the sale of any particular car. Nevertheless, the CEO of Diomedes Motors expects this change in tires to increase Diomedes' profits in the coming year.Which of the following, if true, provides the best reason for the expectation?

Power Plant Spokesperson: "The water quality of the Phage River as it passes through Praseopolis is below federal standards. The citizens of Praseopolis often blame the poor water quality on our coal-burning power plant, which is upstream from Praseopolis. But Vulcan Refinery, along a tributary of the Phage River even further upstream, releases several toxins into the water. Moreover, over 99% of the toxic materials measured in the Phage River in the vicinity of Praseopolis are consistent with metal refining, but not with the by-products of coal combustion."

SafeZone mosquito repellant has been shown in laboratory settings to be effective for twelve hours against the female anopheles mosquito, the only mosquito that transmits malaria. SafeZone, however, is not effective against mosquitoes that do not transmit malaria. The only instance in which SafeZone does not repel the female anopheles mosquito is when this mosquito can detect any ruptured blood vessels, a state that inevitably results whenever any kind of mosquito bites a person. Therefore, assuming one does not have any ruptured blood vessels on their skin before applying SafeZone, that person will not be able to catch malaria for up to twelve hours.Which of the following, if true, would argue most against the use of SafeZone in areas in which malaria is endemic?

When a married couple has frequent emotionally satisfying conversations, they tend in overwhelming percentages to remain married throughout their lives.

A coffee manufacturer wants more restaurant chains to serve its brands of coffee. The manufacturer is considering a plan to offer its coffee to large chains at a significantly lower price, at least for a certain period. This lower price initially will reduce the manufacturer's profits, but they hope to get into enough nationwide restaurant chains that their volume increases significantly. Once they have a much higher volume, even a small increase in their price would have an enormous effect on their profits.In evaluating the plan's chances of success, it would be most helpful to know which of the following?
