What would an engine driver have to do to adjust the more modern type of valve?, Context: Steam engines frequently possess two independent mechanisms for ensuring that the pressure in the boiler does not go too high; one may be adjusted by the user, the second is typically designed as an ultimate fail-safe. Such safety valves traditionally used a simple lever to restrain a plug valve in the top of a boiler. One end of the lever carried a weight or spring that restrained the valve against steam pressure. Early valves could be adjusted by engine drivers, leading to many accidents when a driver fastened the valve down to allow greater steam pressure and more power from the engine. The more recent type of safety valve uses an adjustable spring-loaded valve, which is locked such that operators may not tamper with its adjustment unless a seal illegally is broken. This arrangement is considerably safer.[citation needed]

Which console had a larger selection of video games?, Context: The rivalry between Nintendo and Sega resulted in what has been described as one of the most notable console wars in video game history, in which Sega positioned the Genesis as the "cool" console, with more mature titles aimed at older gamers, and edgy advertisements that occasionally attacked the competition. Nintendo however, scored an early public relations advantage by securing the first console conversion of Capcom's arcade classic Street Fighter II for SNES, which took over a year to make the transition to Genesis. Despite the Genesis's head start, much larger library of games, and lower price point, the Genesis only represented an estimated 60% of the American 16-bit console market in June 1992, and neither console could maintain a definitive lead for several years. Donkey Kong Country is said to have helped establish the SNES's market prominence in the latter years of the 16-bit generation, and for a time, maintain against the PlayStation and Saturn. According to Nintendo, the company had sold more than 20 million SNES units in the U.S. According to a 2014 Wedbush Securities report based on NPD sales data, the SNES ultimately outsold the Genesis in the U.S. market.
