Problem: Beyoncé has worked with Pepsi since 2002, and in 2004 appeared in a Gladiator-themed commercial with Britney Spears, Pink, and Enrique Iglesias. In 2012, Beyoncé signed a $50 million deal to endorse Pepsi. The Center for Science in the Public Interest (CSPINET) wrote Beyoncé an open letter asking her to reconsider the deal because of the unhealthiness of the product and to donate the proceeds to a medical organisation. Nevertheless, NetBase found that Beyoncé's campaign was the most talked about endorsement in April 2013, with a 70 per cent positive audience response to the commercial and print ads.
Who sent her a letter asking that she reconsider the Pepsi deal?
The answer is the following: Center for Science in the Public Interest

Problem: Many contemporary uses of uranium exploit its unique nuclear properties. Uranium-235 has the distinction of being the only naturally occurring fissile isotope. Uranium-238 is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239 in a nuclear reactor. Another fissile isotope, uranium-233, can be produced from natural thorium and is also important in nuclear technology. While uranium-238 has a small probability for spontaneous fission or even induced fission with fast neutrons, uranium-235 and to a lesser degree uranium-233 have a much higher fission cross-section for slow neutrons. In sufficient concentration, these isotopes maintain a sustained nuclear chain reaction. This generates the heat in nuclear power reactors, and produces the fissile material for nuclear weapons. Depleted uranium (238U) is used in kinetic energy penetrators and armor plating.
What can be turned into plutonium-239 in a nuclear reactor?
The answer is the following: Uranium-238

Problem: The total energy of a system can be subdivided and classified in various ways. For example, classical mechanics distinguishes between kinetic energy, which is determined by an object's movement through space, and potential energy, which is a function of the position of an object within a field. It may also be convenient to distinguish gravitational energy, thermal energy, several types of nuclear energy (which utilize potentials from the nuclear force and the weak force), electric energy (from the electric field), and magnetic energy (from the magnetic field), among others. Many of these classifications overlap; for instance, thermal energy usually consists partly of kinetic and partly of potential energy.
What usually consists partly of kinetic and partly of potential energy?
The answer is the following: thermal energy

Problem: Encouraged by these successes, Nintendo soon turned its attention to the North American market. Nintendo entered into negotiations with Atari to release the Famicom under Atari’s name as the name Nintendo Advanced Video Gaming System. The deal was set to be finalized and signed at the Summer Consumer Electronics Show in June 1983. However, Atari discovered at that show that its competitor Coleco was illegally demonstrating its Coleco Adam computer with Nintendo's Donkey Kong game. This violation of Atari's exclusive license with Nintendo to publish the game for its own computer systems delayed the implementation of Nintendo's game console marketing contract with Atari. Atari's CEO Ray Kassar was fired the next month, so the deal went nowhere, and Nintendo decided to market its system on its own.g[›]
What was the name of the fired Atari CEO?
The answer is the following:
Ray Kassar
