Article: Aerobic gymnastics (formally Sport Aerobics) involves the performance of routines by individuals, pairs, trios or groups up to 6 people, emphasizing strength, flexibility, and aerobic fitness rather than acrobatic or balance skills. Routines are performed for all individuals on a 7x7m floor and also for 12–14 and 15-17 trios and mixed pairs. From 2009, all senior trios and mixed pairs were required to be on the larger floor (10x10m), all groups also perform on this floor. Routines generally last 60–90 seconds depending on age of participant and routine category.

Question: What does aerobic gymnastiscs involve?

Article: Florida is among the three states with the most severe felony disenfranchisement laws. Florida requires felons to have completed sentencing, parole and/or probation, and then seven years later, to apply individually for restoration of voting privileges. As in other aspects of the criminal justice system, this law has disproportionate effects for minorities. As a result, according to Brent Staples, based on data from The Sentencing Project, the effect of Florida's law is such that in 2014 "[m]ore than one in ten Floridians – and nearly one in four African-American Floridians – are shut out of the polls because of felony convictions."

Question: Who does this law effect most 
Ans: this law has disproportionate effects for minorities


Article: Upon exposure, the amount of light energy that reaches the film determines the effect upon the emulsion. If the brightness of the light is multiplied by a factor and the exposure of the film decreased by the same factor by varying the camera's shutter speed and aperture, so that the energy received is the same, the film will be developed to the same density. This rule is called reciprocity. The systems for determining the sensitivity for an emulsion are possible because reciprocity holds. In practice, reciprocity works reasonably well for normal photographic films for the range of exposures between 1/1000 second to 1/2 second. However, this relationship breaks down outside these limits, a phenomenon known as reciprocity failure.

Question: How is the exposure of film changed?
Ans: by varying the camera's shutter speed and aperture


Article: 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.

Question: When was the George Warren Brown School of Social Work founded?
Ans:
