Compared to Lee and Yang, Feynman and Gell-Mann
A called on Wu to help them confirm rather than disprove a theory.
B studied medical sciences instead of physical sciences.
C worked on the Manhattan Project in lieu of purely academic research.
D would make relatively minor discoveries in physics.
The correct answer is C worked on the Manhattan Project in lieu of purely academic research.
Explanation: Richard Feynman and Murray Gell-Mann were both involved in the Manhattan Project, which was a significant wartime effort to develop nuclear weapons during World War II. In contrast, Lee and Yang are primarily recognized for their theoretical contributions in quantum physics and were not part of this project. This distinction highlights the different paths and focuses of their scientific careers.
