Question

what is the primary reason that arthur compton disagrees with the writers of the oak ridge petition?
failure to use the bomb might lead to greater american loss of life.
the new bombs were not capable of making an effective military demonstration.
the use of atomic weapons had been outlawed by international agreement.
the proposal is to make a technical but not military demonstration, preparing the way for a recommendation by the united states that the military use of atomic explosives be outlawed by firm international agreement.
i note that two important considerations have not been mentioned:
(1) that failure to make a military demonstration of the new bombs may make the war longer and more expensive on human lives, and
(2) that without a military demonstration it may be impossible to impress the world with

Explanation:

Arthur Compton's first consideration in the text emphasizes that failure to use the bomb (military demonstration) could lead to a longer war and more American lives lost. The Oak Ridge Petition likely favored a non - military (technical) demonstration. So, Compton's main disagreement is based on the potential for greater American loss of life if the bomb isn't used (military demonstration). The second option is wrong as the text doesn't suggest the bombs couldn't make an effective military demonstration. The third option is incorrect because the text is about a proposal to outlaw military use after a demonstration, not that it was already outlawed.

Answer:

Failure to use the bomb might lead to greater American loss of life.
