Please answer this: Given the following passage  "There has, however, been interest among railroad operators in returning to DC use at higher voltages than previously used. At the same voltage, DC often has less loss than AC, and for this reason high-voltage direct current is already used on some bulk power transmission lines. DC avoids the electromagnetic radiation inherent with AC, and on a railway this also reduces interference with signalling and communications and mitigates hypothetical EMF risks. DC also avoids the power factor problems of AC. Of particular interest to railroading is that DC can supply constant power with a single ungrounded wire. Constant power with AC requires three-phase transmission with at least two ungrounded wires. Another important consideration is that mains-frequency 3-phase AC must be carefully planned to avoid unbalanced phase loads. Parts of the system are supplied from different phases on the assumption that the total loads of the 3 phases will even out. At the phase break points between regions supplied from different phases, long insulated supply breaks are required to avoid them being shorted by rolling stock using more than one pantograph at a time. A few railroads have tried 3-phase but its substantial complexity has made single-phase standard practice despite the interruption in power flow that occurs twice every cycle. An experimental 6 kV DC railway was built in the Soviet Union.",  answer the following question. Note that the answer is present within the text.  Question: DC is less hazardous than AC because it generates less?

Answer: electromagnetic radiation


Please answer this: Given the following passage  "UNFPA provided aid to Peru's reproductive health program in the mid-to-late '90s. When it was discovered a Peruvian program had been engaged in carrying out coercive sterilizations, UNFPA called for reforms and protocols to protect the rights of women seeking assistance. UNFPA was not involved in the scandal, but continued work with the country after the abuses had become public to help end the abuses and reform laws and practices.",  answer the following question. Note that the answer is present within the text.  Question: What is opposite of begin?

Answer: end


Please answer this: Given the following passage  "In August 2013, a launching ceremony for Japan's largest military ship since World War II was held in Yokohama. The 820-foot-long (250 m), 19,500-ton flattop Izumo was deployed in March 2015. The ship is able to carry up to 14 helicopters; however, only seven ASW helicopters and two SAR helicopters were planned for the initial aircraft complement. For other operations, 400 troops and fifty 3.5 t trucks (or equivalent equipment) can also be carried. The flight deck has five helicopter landing spots that allow simultaneous landings or take-offs. The ship is equipped with two Phalanx CIWS and two SeaRAM for its defense. The destroyers of this class were initially intended to replace the two ships of the Shirane class, which were originally scheduled to begin decommissioning in FY2014.",  answer the following question. Note that the answer is present within the text.  Question: How many non aircraft can be put on the ship?
++++++++
Answer:
fifty
