Problem: Please answer a question about the following article about Predation:
Predators are often another organism's prey, and likewise prey are often predators. Though blue jays prey on insects, they may in turn be prey for cats and snakes, and snakes may be the prey of hawks. One way of classifying predators is by trophic level. Organisms that feed on autotrophs, the producers of the trophic pyramid, are known as herbivores or primary consumers; those that feed on heterotrophs such as animals are known as secondary consumers. Secondary consumers are a type of carnivore, but there are also tertiary consumers eating these carnivores, quartary consumers eating them, and so forth. Because only a fraction of energy is passed on to the next level, this hierarchy of predation must end somewhere, and very seldom goes higher than five or six levels, and may go only as high as three trophic levels (for example, a lion that preys upon large herbivores such as wildebeest, which in turn eat grasses). A predator at the top of any food chain (that is, one that is preyed upon by no organism) is called an apex predator; examples include the orca, sperm whale, anaconda, Komodo dragon, tiger, lion, tiger shark, Nile crocodile, and most eagles and owls—and even omnivorous humans and grizzly bears. An apex predator in one environment may not retain this position as a top predator if introduced to another habitat, such as a dog among alligators, a skunk in the presence of the great horned owl immune to skunk spray, or a snapping turtle among jaguars; a predatory species introduced into an area where it faces no predators, such as a domestic cat or a dog in some insular environments, can become an apex predator by default.
When a new apex predator moves into an area this changes. 
A: trophic pyramid
Problem: Please answer a question about the following article about Washington University in St. Louis:
With roots dating back to 1909 in the university's School of Social Economy, the George Warren Brown School of Social Work (commonly called the Brown School or Brown) was founded in 1925. Brown's academic degree offerings include a Master of Social Work (MSW), a Master of Public Health (MPH), a PhD in Social Work, and a PhD in Public Health Sciences. It is currently ranked first among Master of Social Work programs in the United States. The school was endowed by Bettie Bofinger Brown and named for her husband, George Warren Brown, a St. Louis philanthropist and co-founder of the Brown Shoe Company. The school was the first in the country to have a building for the purpose of social work education, and it is also a founding member of the Association of Schools and Programs of Public Health. The school is housed within Brown and Goldfarb Halls, but a third building expansion is currently in progress and slated to be completed in summer 2015. The new building, adjacent to Brown and Goldfarb Halls, targets LEED Gold certification and will add approximately 105,000 square feet, more than doubling the school's teaching, research, and program space.
By what other names is the George Warren Brown School of Social Work known?
A: Brown School or Brown
Problem: Please answer a question about the following article about Copyright infringement:
The U.S. GAO's 2010 findings regarding the great difficulty of accurately gauging the economic impact of copyright infringement was reinforced within the same report by the body's research into three commonly cited estimates that had previously been provided to U.S. agencies. The GAO report explained that the sources – a Federal Bureau of Investigation (FBI) estimate, a Customs and Border Protection (CBP) press release and a Motor and Equipment Manufacturers Association estimate – "cannot be substantiated or traced back to an underlying data source or methodology."
What report said the data could not be substantiated or traced to a reliable data source?
A:
GAO report
