Ivy Mike

Target entity: Ivy Mike
Context triple: [Teller–Ulam design, firstTestedIn, Ivy Mike]

• A. Trinity test device
  The Trinity test device was the first nuclear explosive ever detonated, a plutonium-based implosion bomb tested by the Manhattan Project in July 1945.
• B. Little Boy
  Little Boy was the codename for the uranium-based atomic bomb dropped on Hiroshima, Japan, by the United States on August 6, 1945, marking the first use of nuclear weapons in warfare.
• C. Castle Bravo
  Castle Bravo was the United States’ first and most powerful dry-fuel thermonuclear (hydrogen) bomb test, conducted in 1954 and infamous for its unexpectedly massive yield and severe radioactive fallout.
• D. Minuteman III
  Minuteman III is an American intercontinental ballistic missile (ICBM) that has served as a key land-based component of the United States' nuclear deterrent since the 1970s.
• E. Chicago Pile-2
  Chicago Pile-2 was an early research nuclear reactor built at the Argonne site to continue and expand experimental work following the first controlled chain reaction achieved by Chicago Pile-1.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
