Question: Copper's greater conductivity versus other metals enhances the electrical energy efficiency of motors. This is important because motors and motor-driven systems account for 43%-46% of all global electricity consumption and 69% of all electricity used by industry. Increasing the mass and cross section of copper in a coil increases the electrical energy efficiency of the motor. Copper motor rotors, a new technology designed for motor applications where energy savings are prime design objectives, are enabling general-purpose induction motors to meet and exceed National Electrical Manufacturers Association (NEMA) premium efficiency standards.
Try to answer this question if possible: What property of copper ruins the efficiency of electrical motors?
Answer: unanswerable

Question: General Ridgway was appointed Supreme Commander, Korea; he regrouped the UN forces for successful counterattacks, while General James Van Fleet assumed command of the U.S. Eighth Army. Further attacks slowly depleted the PVA and KPA forces; Operations Courageous (2328 March 1951) and Tomahawk (23 March 1951) were a joint ground and airborne infilltration meant to trap Chinese forces between Kaesong and Seoul. UN forces advanced to "Line Kansas", north of the 38th parallel. The 187th Airborne Regimental Combat Team's ("Rakkasans") second of two combat jumps was on Easter Sunday, 1951, at Munsan-ni, South Korea, codenamed Operation Tomahawk. The mission was to get behind Chinese forces and block their movement north. The 60th Indian Parachute Field Ambulance provided the medical cover for the operations, dropping an ADS and a surgical team and treating over 400 battle casualties apart from the civilian casualties that formed the core of their objective as the unit was on a humanitarian mission.
Try to answer this question if possible: Who was appointed Supreme Commander in Korea after the removal of General MacArthur?
Answer: General Ridgway
Question: Detroit techno is an offshoot of Chicago house music. It was developed starting in the late 80s, one of the earliest hits being "Big Fun" by Inner City. Detroit techno developed as the legendary disc jockey The Electrifying Mojo conducted his own radio program at this time, influencing the fusion of eclectic sounds into the signature Detroit techno sound. This sound, also influenced by European electronica (Kraftwerk, Art of Noise), Japanese synthpop (Yellow Magic Orchestra), early B-boy Hip-Hop (Man Parrish, Soul Sonic Force) and Italo disco (Doctor's Cat, Ris, Klein M.B.O.), was further pioneered by Juan Atkins, Derrick May, and Kevin Saunderson, the "godfathers" of Detroit Techno.[citation needed]
