(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:

The text on the right mentions that failure to make a military demonstration (i.e., not using the bomb) may make the war longer and more expensive in human lives. This aligns with the first option which states that failure to use the bomb might lead to greater American loss of life. The second option is incorrect as there is no indication in the text that the bombs couldn't make an effective military demonstration. The third option is wrong because the text is about a proposal to outlaw the military use of atomic explosives, not that it had already been outlawed.

Answer:

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