On 18 June 1948, the National Security Council issued Directive 10/2 calling for covert action against the USSR, and granting the authority to carry out covert operations against "hostile foreign states or groups" that could, if needed, be denied by the U.S. government. To this end, the Office of Policy Coordination was created inside the new CIA. The OPC was quite unique; Frank Wisner, the head of the OPC, answered not to the CIA Director, but to the secretaries of defense, state, and the NSC, and the OPC's actions were a secret even from the head of the CIA. Most CIA stations had two station chiefs, one working for the OSO, and one working for the OPC.
Who was the head of the OPC?
A: Frank Wisner

Another significant change undergone by many of these newly agrarian communities was one of diet. Pre-agrarian diets varied by region, season, available local plant and animal resources and degree of pastoralism and hunting. Post-agrarian diet was restricted to a limited package of successfully cultivated cereal grains, plants and to a variable extent domesticated animals and animal products. Supplementation of diet by hunting and gathering was to variable degrees precluded by the increase in population above the carrying capacity of the land and a high sedentary local population concentration. In some cultures, there would have been a significant shift toward increased starch and plant protein. The relative nutritional benefits and drawbacks of these dietary changes and their overall impact on early societal development is still debated.
What was included in the local diet?
A: unanswerable

Gaddafi briefly studied History at the University of Libya in Benghazi, before dropping out to join the military. Despite his police record, in 1963 he began training at the Royal Military Academy, Benghazi, alongside several like-minded friends from Misrata. The armed forces offered the only opportunity for upward social mobility for underprivileged Libyans, and Gaddafi recognised it as a potential instrument of political change. Under Idris, Libya's armed forces were trained by the British military; this angered Gaddafi, who viewed the British as imperialists, and accordingly he refused to learn English and was rude to the British officers, ultimately failing his exams. British trainers reported him for insubordination and abusive behaviour, stating their suspicion that he was involved in the assassination of the military academy's commander in 1963. Such reports were ignored and Gaddafi quickly progressed through the course.
How did Gaddafi view the influence of the military?
A: the only opportunity for upward social mobility for underprivileged Libyans, and Gaddafi recognised it as a potential instrument of political change

In the past, small batches of amorphous metals with high surface area configurations (ribbons, wires, films, etc.) have been produced through the implementation of extremely rapid rates of cooling. This was initially termed "splat cooling" by doctoral student W. Klement at Caltech, who showed that cooling rates on the order of millions of degrees per second is sufficient to impede the formation of crystals, and the metallic atoms become "locked into" a glassy state. Amorphous metal wires have been produced by sputtering molten metal onto a spinning metal disk. More recently a number of alloys have been produced in layers with thickness exceeding 1 millimeter. These are known as bulk metallic glasses (BMG). Liquidmetal Technologies sell a number of zirconium-based BMGs. Batches of amorphous steel have also been produced that demonstrate mechanical properties far exceeding those found in conventional steel alloys.
What type of metal makes better alloys than Caltech?
A:
unanswerable
