The practice has received both advocacy and criticism. Putting clocks forward benefits retailing, sports, and other activities that exploit sunlight after working hours, but can cause problems for evening entertainment and for other activities tied to sunlight, such as farming. Although some early proponents of DST aimed to reduce evening use of incandescent lighting, which used to be a primary use of electricity, modern heating and cooling usage patterns differ greatly and research about how DST affects energy use is limited or contradictory.

What used to be the main draw on electricity?
Answer: incandescent lighting

In 1976, a group of Italian American professors at City University of New York asked to be added as an affirmative action category for promotion and hiring. Italian Americans are usually considered white in the US and would not be covered under affirmative action policies, but the professors believed they were underrepresented. Libertarian economist Thomas Sowell wrote in his book, Affirmative Action Around the World: An Empirical Study, that affirmative action policies encourage non-preferred groups to designate themselves as members of preferred groups [i.e., primary beneficiaries of affirmative action] to take advantage of group preference policies.

What was the title of the book written by Thomas Sowell?
Answer: Affirmative Action Around the World: An Empirical Study

The legal process to change the definition of the kilogram is already underway, but it had been decided that no final decision would be made before the next meeting of the General Conference on Weights and Measures in 2011. (For more detailed information, see kilogram definitions.) The Planck constant is a leading contender to form the basis of the new definition, although not the only one. Possible new definitions include "the mass of a body at rest whose equivalent energy equals the energy of photons whose frequencies sum to 7050135639273999999♠135639274×1042 Hz", or simply "the kilogram is defined so that the Planck constant equals 6966662606895999999♠6.62606896×10−34 J⋅s".

The mass of a resting body with what energy would be equal to a kilogram?
Answer:
7050135639273999999♠135639274×1042 Hz
