QUES: Disadvantages of electric traction include high capital costs that may be uneconomic on lightly trafficked routes; a relative lack of flexibility since electric trains need electrified tracks or onboard supercapacitors and charging infrastructure at stations; and a vulnerability to power interruptions. Different regions may use different supply voltages and frequencies, complicating through service. The limited clearances available under catenaries may preclude efficient double-stack container service. The lethal voltages on contact wires and third rails are a safety hazard to track workers, passengers and trespassers. Overhead wires are safer than third rails, but they are often considered unsightly.
Lethal voltages on contact wires and third rails are non a safety hazard for whom?

ANS: unanswerable

QUES: During the Hungnam evacuation, about 193 shiploads of UN Command forces and matériel (approximately 105,000 soldiers, 98,000 civilians, 17,500 vehicles, and 350,000 tons of supplies) were evacuated to Pusan. The SS Meredith Victory was noted for evacuating 14,000 refugees, the largest rescue operation by a single ship, even though it was designed to hold 12 passengers. Before escaping, the UN Command forces razed most of Hungnam city, especially the port facilities; and on 16 December 1950, President Truman declared a national emergency with Presidential Proclamation No. 2914, 3 C.F.R. 99 (1953), which remained in force until 14 September 1978.[b] The next day (17 December 1950) Kim Il-sung was deprived of the right of command of KPA by China. After that, the leading part of the war became the Chinese army. Following that, on 1 February 1951, United Nations General Assembly adopted a draft resolution condemning China as an aggressor in the Korean War.
What was the name of the ship responsible for undertaking the largest rescue operation by a single ship?

ANS: SS Meredith Victory

QUES: Burke was not merely presenting a peace agreement to Parliament; rather, he stepped forward with four reasons against using force, carefully reasoned. He laid out his objections in an orderly manner, focusing on one before moving to the next. His first concern was that the use of force would have to be temporary, and that the uprisings and objections to British governance in America would not be. Second, Burke worried about the uncertainty surrounding whether Britain would win a conflict in America. "An armament", Burke said, "is not a victory". Third, Burke brought up the issue of impairment; it would do the British Government no good to engage in a scorched earth war and have the object they desired (America) become damaged or even useless. The American colonists could always retreat into the mountains, but the land they left behind would most likely be unusable, whether by accident or design. The fourth and final reason to avoid the use of force was experience; the British had never attempted to rein in an unruly colony by force, and they did not know if it could be done, let alone accomplished thousands of miles away from home. Not only were all of these concerns reasonable, but some turned out to be prophetic – the American colonists did not surrender, even when things looked extremely bleak, and the British were ultimately unsuccessful in their attempts to win a war fought on American soil.
How many reasons in favor of the use of force did Burke present?

ANS: unanswerable

QUES: In 2010 and 2011, state and federal funds were awarded to Connecticut (and Massachusetts) to construct the Hartford Line, with a southern terminus at New Haven's Union Station and a northern terminus at Springfield's Union Station. According to the White House, "This corridor [currently] has one train per day connecting communities in Connecticut and Massachusetts to the Northeast Corridor and Vermont. The vision for this corridor is to restore the alignment to its original route via the Knowledge Corridor in western Massachusetts, improving trip time and increasing the population base that can be served." Set for construction in 2013, the "Knowledge Corridor high speed intercity passenger rail" project will cost approximately $1 billion, and the ultimate northern terminus for the project is reported to be Montreal in Canada. Train speeds between will reportedly exceed 110 miles per hour (180 km/h) and increase both cities' rail traffic exponentially.
In what year was the "Knowledge corridor high speed intercity passenger rail" slated for construction?

ANS:
2013
