QUES: U.S. President Barack Obama has rarely used the term, but in his inaugural address on 20 January 2009, he stated "Our nation is at war, against a far-reaching network of violence and hatred." In March 2009 the Defense Department officially changed the name of operations from "Global War on Terror" to "Overseas Contingency Operation" (OCO). In March 2009, the Obama administration requested that Pentagon staff members avoid use of the term, instead using "Overseas Contingency Operation". Basic objectives of the Bush administration "war on terror", such as targeting al Qaeda and building international counterterrorism alliances, remain in place. In December 2012, Jeh Johnson, the General Counsel of the Department of Defense, stated that the military fight will be replaced by a law enforcement operation when speaking at Oxford University, predicting that al Qaeda will be so weakened to be ineffective, and has been "effectively destroyed", and thus the conflict will not be an armed conflict under international law. In May 2013, Obama stated that the goal is "to dismantle specific networks of violent extremists that threaten America"; which coincided with the U.S. Office of Management and Budget having changed the wording from "Overseas Contingency Operations" to "Countering Violent Extremism" in 2010.
Who said in 2012 that the fight would change from military to law enforcement?

ANS: Jeh Johnson

QUES: In classical physics, an inertial reference frame is one in which an object that experiences no forces does not accelerate. In general relativity, an inertial frame of reference is one that is following a geodesic of space-time. An object that moves against a geodesic experiences a force. An object in free fall does not experience a force, because it is following a geodesic. An object standing on the earth, however, will experience a force, as it is being held against the geodesic by the surface of the planet. In light of this, the bucket of water rotating in empty space will experience a force because it rotates with respect to the geodesic. The water will become concave, not because it is rotating with respect to the distant stars, but because it is rotating with respect to the geodesic.
What holds an object standing on earth against the geodesic?

ANS: the surface of the planet

QUES: Various disco songs incorporated sounds produced with synthesizers and drum machines, and some compositions were entirely electronic; examples include Giorgio Moroder's late 1970s productions such as Donna Summer's hit single "I Feel Love" from 1977, Cerrone's "Supernature" (1977), Yellow Magic Orchestra's synth-disco-pop productions from Yellow Magic Orchestra (1978), Solid State Survivor (1979), and several early 1980s disco-pop productions by the Hi-NRG group Lime.
What year did Cerrone's "Yellow" get released?

ANS: unanswerable

QUES: After 1857, the colonial government strengthened and expanded its infrastructure via the court system, legal procedures, and statutes. The Indian Penal Code came into being. In education, Thomas Babington Macaulay had made schooling a priority for the Raj in his famous minute of February 1835 and succeeded in implementing the use of English as the medium of instruction. By 1890 some 60,000 Indians had matriculated. The Indian economy grew at about 1% per year from 1880 to 1920, and the population also grew at 1%. However, from 1910s Indian private industry began to grow significantly. India built a modern railway system in the late 19th century which was the fourth largest in the world. The British Raj invested heavily in infrastructure, including canals and irrigation systems in addition to railways, telegraphy, roads and ports. However, historians have been bitterly divided on issues of economic history, with the Nationalist school arguing that India was poorer at the end of British rule than at the beginning and that impoverishment occurred because of the British.
When did India build the forth largest rail system in the world?

ANS:
late 19th century
