Question: The Spanish Empire and other Europeans brought horses to the Americas. Some of these animals escaped and began to breed and increase their numbers in the wild. The re-introduction of the horse, extinct in the Americas for over 7500 years, had a profound impact on Native American culture in the Great Plains of North America and of Patagonia in South America. By domesticating horses, some tribes had great success: horses enabled them to expand their territories, exchange more goods with neighboring tribes, and more easily capture game, especially bison.
Try to answer this question if possible: How long had horses been extinct in the Americas prior to their re-introduction?
Answer: 7500 years
Question: Water storage and supply for Melbourne is managed by Melbourne Water, which is owned by the Victorian Government. The organisation is also responsible for management of sewerage and the major water catchments in the region as well as the Wonthaggi desalination plant and NorthSouth Pipeline. Water is stored in a series of reservoirs located within and outside the Greater Melbourne area. The largest dam, the Thomson River Dam, located in the Victorian Alps, is capable of holding around 60% of Melbourne's water capacity, while smaller dams such as the Upper Yarra Dam, Yan Yean Reservoir, and the Cardinia Reservoir carry secondary supplies.

Answer: the Victorian Government
Question: In the year 2000, according to a study by American Association of University Professors (AAUP), affirmative action promoted diversity within colleges and universities. This has been shown to have positive effects on the educational outcomes and experiences of college students as well as the teaching of faculty members. According to a study by Geoffrey Maruyama and Jose F. Moreno, the results showed that faculty members believed diversity helps students to reach the essential goals of a college education, Caucasian students suffer no detrimental effects from classroom diversity, and that attention to multicultural learning improves the ability of colleges and universities to accomplish their missions. Furthermore, a diverse population of students offers unique perspectives in order to challenge preconceived notions through exposure to the experiences and ideas of others. According to Professor Gurin of the University of Michigan, skills such as "perspective-taking, acceptance of differences, a willingness and capacity to find commonalities among differences, acceptance of conflict as normal, conflict resolution, participation in democracy, and interest in the wider social world" can potentially be developed in college while being exposed to heterogeneous group of students. In addition, broadening perspectives helps students confront personal and substantive stereotypes and fosters discussion about racial and ethnic issues in a classroom setting. Furthermore, the 2000 AAUP study states that having a diversity of views leads to a better discussion and greater understanding among the students on issues of race, tolerance, fairness, etc.

Question: The "photoelectrons" emitted as a result of the photoelectric effect have a certain kinetic energy, which can be measured. This kinetic energy (for each photoelectron) is independent of the intensity of the light, but depends linearly on the frequency; and if the frequency is too low (corresponding to a photon energy that is less than the work function of the material), no photoelectrons are emitted at all, unless a plurality of photons, whose energetic sum is greater than the energy of the photoelectrons, acts virtually simultaneously (multiphoton effect) Assuming the frequency is high enough to cause the photoelectric effect, a rise in intensity of the light source causes more photoelectrons to be emitted with the same kinetic energy, rather than the same number of photoelectrons to be emitted with higher kinetic energy.
Try to answer this question if possible: What does the kinetic energy of a photoelectron lose?
Answer:
unanswerable
