Information: - The United States Armed Forces are the federal armed forces of the United States. They consist of the Army, Marine Corps, Navy, Air Force, and Coast Guard. The President of the United States is the military's overall head, and helps form military policy with the U.S. Department of Defense (DoD), a federal executive department, acting as the principal organ by which military policy is carried out. From the time of its inception, the military played a decisive role in the history of the United States. A sense of national unity and identity was forged as a result of victory in the First Barbary War and the Second Barbary War. Even so, the Founders were suspicious of a permanent military force. It played an important role in the American Civil War, where leading generals on both sides were picked from members of the United States military. Not until the outbreak of World WarII did a large standing army become officially established. The National Security Act of 1947, adopted following World WarII and during the Cold War's onset, created the modern U.S. military framework; the Act merged previously Cabinet-level Department of War and the Department of the Navy into the National Military Establishment (renamed the Department of Defense in 1949), headed by the Secretary of Defense; and created the Department of the Air Force and National Security Council. - General Raymond "Ray" Thomas Odierno (born 8 September 1954) is a retired United States Army general who served as the 38th Chief of Staff of the Army. Prior to his service as Chief of Staff, Odierno commanded United States Joint Forces Command from October 2010 until its disestablishment in August 2011. He served as Commanding General, United States Forces Iraq and its predecessor, Multi-National Force Iraq, from September 2008 through September 2010. Before then, he served as Commanding General, III Corps, from May 2006 to May 2008. Odierno is the twelfth American military officer to command at the Division, Corps, and Army level during the same conflict and only the second with this distinction since the Vietnam War. Before commanding III Corps, he served as Assistant to the Chairman of the Joint Chiefs of Staff in Washington, where he was the primary military adviser to Secretary of State Condoleezza Rice from 3 November 2004 to 1 May 2006. - Admiral Harold W. Gehman , Jr. is a retired United States Navy four - star admiral who served as NATO 's Supreme Allied Commander , Atlantic ( SACLANT ) , Commander - in - Chief of the United States Joint Forces Command , one of the United States ' Unified Combatant Commands , and Vice Chief of Naval Operations . He was also the Co-Chairman of the Commission that investigated the terrorist attack on the USS Cole and was Chairman of the Columbia Accident Investigation Board ( CAIB ) after the Space Shuttle Columbia disintegrated during reentry in 2003 , killing all seven crew members . - Robert Michael "Bob" Gates (born September 25, 1943) is an American statesman, scholar and university president who served as the 22nd United States Secretary of Defense from 2006 to 2011. Gates initially began his career serving as an officer in the United States Air Force but was quickly recruited by the CIA. Gates served for 26 years in the Central Intelligence Agency and the National Security Council, and was Director of Central Intelligence under President George H. W. Bush. After leaving the CIA, Gates became president of Texas A&M University and was a member of several corporate boards. Gates served as a member of the Iraq Study Group, the bipartisan commission co-chaired by James A. Baker III and Lee H. Hamilton, that studied the lessons of the Iraq War. - United States Joint Forces Command (USJFCOM) was a Unified Combatant Command of the United States Armed Forces. USJFCOM was a functional command that provided specific services to the military. The last commander was Army Gen. Raymond T. Odierno. As directed by the President to identify opportunities to cut costs and rebalance priorities, Defense Secretary Robert Gates recommended that USJFCOM be disestablished and its essential functions reassigned to other unified combatant commands. Formal disestablishment occurred on 4 August 2011. What object entity has the relation of 'conflict' with the subject 'harold w. gehman'? Choices: - american civil war - cold war - first barbary war - iraq war - second barbary war - vietnam war - world war ii

*Question*
Information: - Nuclear weapon designs are physical, chemical, and engineering arrangements that cause the physics package of a nuclear weapon to detonate. There are three existing basic design types. In many existing designs, the explosive energy of deployed devices is derived primarily from nuclear fission, not fusion. (This includes fission of any U-238 tamper or casing due to fusion produced neutrons.) - A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion (thermonuclear weapon). Both reactions release vast quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released the same amount of energy as approximately . The first thermonuclear ("hydrogen") bomb test released the same amount of energy as approximately . - The Mark 5 nuclear bomb and W5 nuclear warhead were a common core nuclear weapon design , designed in the early 1950s and which saw service from 1952 to 1963 . - In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay. - The neutron is a subatomic particle, symbol or , with no net electric charge and a mass slightly larger than that of a proton. Protons and neutrons, each with mass approximately one atomic mass unit, constitute the nucleus of an atom, and they are collectively referred to as nucleons. Their properties and interactions are described by nuclear physics. What object entity has the relation of 'use' with the subject 'mark 5 nuclear bomb'? Choices: - engineering - mass - nuclear fission - nuclear weapon
**Answer**
nuclear fission
