Article: As another example, she points to work by Thomas et al., who sought to distinguish between the Y chromosomes of Jewish priests (Kohanim), (in Judaism, membership in the priesthood is passed on through the father's line) and the Y chromosomes of non-Jews. Abu el-Haj concluded that this new "race science" calls attention to the importance of "ancestry" (narrowly defined, as it does not include all ancestors) in some religions and in popular culture, and people's desire to use science to confirm their claims about ancestry; this "race science", she argues, is fundamentally different from older notions of race that were used to explain differences in human behaviour or social status:

Question: What is fundamentally different from older notions of race?
Ans: race science

Article: 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.

Question: What did a study performed by Schwabe and wolf show?
Ans: memory impairment and the detrimental effects of stress on learning can be attenuated.

Article: FDR's New Deal programs often contained equal opportunity clauses stating "no discrimination shall be made on account of race, color or creed",:11 but the true forerunner to affirmative action was the Interior Secretary of the time, Harold L. Ickes. Ickes prohibited discrimination in hiring for Public Works Administration funded projects and oversaw not only the institution of a quota system, where contractors were required to employ a fixed percentage of Black workers, by Robert C. Weaver and Clark Foreman,:12 but also the equal pay of women proposed by Harry Hopkins.:14FDR's largest contribution to affirmative action, however, lay in his Executive Order 8802 which prohibited discrimination in the defense industry or government.:22 The executive order promoted the idea that if taxpayer funds were accepted through a government contract, then all taxpayers should have an equal opportunity to work through the contractor.:234 To enforce this idea, Roosevelt created the Fair Employment Practices Committee (FEPC) with the power to investigate hiring practices by government contractors.:22

Question: Which piece of legislation prevented any discrimination in the defense industry and government?
Ans: Executive Order 8802

Article: The national postal infrastructure was completely destroyed during the civil war. In order to fill the vacuum, Somali Post signed an agreement in 2003 with the United Arab Emirates' Emirates Post to process mail to and from Somalia. Emirates Post's mail transit hub at the Dubai International Airport was then used to forward mail from Somalia to the UAE and various Western destinations, including Italy, the Netherlands, the United Kingdom, Sweden, Switzerland and Canada.

Question: When was the infrastructure of the postal service destroyed?
Ans:
during the civil war
