A study in 2007 by Mark Long, an economics professor at the University of Washington, demonstrated that the alternatives of affirmative action proved ineffective in restoring minority enrollment in public flagship universities in California, Texas, and Washington. More specifically, apparent rebounds of minority enrollment can be explained by increasing minority enrollment in high schools of those states, and the beneficiaries of class-based (not race) affirmative action would be white students. At the same time, affirmative action itself is both morally and materially costly: 52 percent of white populace (compared to 14 percent of black) thought it should be abolished, implying white distaste of using racial identity, and full-file review is expected to cost the universities an additional $1.5 million to $2 million per year, excluding possible cost of litigation.
What area of study did professor Mark Long have a job in?
A: unanswerable

In Asia, various Chinese dynasties and Japanese shogunates controlled the Asian sphere. In Japan, the Edo period from 1600 to 1868 is also referred to as the early modern period. And in Korea, from the rising of Joseon Dynasty to the enthronement of King Gojong is referred to as the early modern period. In the Americas, Native Americans had built a large and varied civilization, including the Aztec Empire and alliance, the Inca civilization, the Mayan Empire and cities, and the Chibcha Confederation. In the west, the European kingdoms and movements were in a movement of reformation and expansion. Russia reached the Pacific coast in 1647 and consolidated its control over the Russian Far East in the 19th century.
What is the 'Early Modern period" known as in Japan?
A: the rising of Joseon Dynasty to the enthronement of King Gojong

However, memory performance can be enhanced when material is linked to the learning context, even when learning occurs under stress. A separate study by cognitive psychologists Schwabe and Wolf shows that when retention testing is done in a context similar to or congruent with the original learning task (i.e., in the same room), memory impairment and the detrimental effects of stress on learning can be attenuated. Seventy-two healthy female and male university students, randomly assigned to the SECPT stress test or to a control group, were asked to remember the locations of 15 pairs of picture cards a computerized version of the card game "Concentration" or "Memory". The room in which the experiment took place was infused with the scent of vanilla, as odour is a strong cue for memory. Retention testing took place the following day, either in the same room with the vanilla scent again present, or in a different room without the fragrance. The memory performance of subjects who experienced stress during the object-location task decreased significantly when they were tested in an unfamiliar room without the vanilla scent (an incongruent context); however, the memory performance of stressed subjects showed no impairment when they were tested in the original room with the vanilla scent (a congruent context). All participants in the experiment, both stressed and unstressed, performed faster when the learning and retrieval contexts were similar.
What did a study performed by Schwabe and wolf show?
A: memory impairment and the detrimental effects of stress on learning can be attenuated.

German beacons operated on the medium-frequency band and the signals involved a two-letter Morse identifier followed by a lengthy time-lapse which enabled the Luftwaffe crews to determine the signal's bearing. The Meacon system involved separate locations for a receiver with a directional aerial and a transmitter. The receipt of the German signal by the receiver was duly passed to the transmitter, the signal to be repeated. The action did not guarantee automatic success. If the German bomber flew closer to its own beam than the Meacon then the former signal would come through the stronger on the direction finder. The reverse would apply only if the meacon were closer.
What two letter identifier did the signal have?
A:
Morse
