b.

c.

d.

e.

B. Soldiers did not possess the scientific expertise to analyze the chemical compositions.

C. Poison gas attacks were often large-scale and unpredictable.

Explanation:

These were two of the reasons why chemical warfare was considered to be a particularly deadly threat during World War I. First of all, chemical warfare was a serious threat due to the fact that soldiers could not analyze the compositions of the chemicals employed. This meant that soldiers were unable to adequately prepare for each type of threat. Moreover, poison gas attacks could not be accurately directed to specific people. Instead, they harmed everything in sight. This meant that poison gas attacks were often large-scale and unpredictable.

explanation:

there are two statements that are incorrect.

1. the marshall plan was a lend lease program. it was an economic plan that europe redevelop itself after wwii.

2. einstein didn't really do anything to further the allied cause in building the bomb. he merely sent a letter to fdr telling him (in 1939) that if the united states entered the war, perhaps it would be wise to build the bomb before germany did. i would say this answer is incorrect, but when america entered the war 2 years later, fdr thought it might be a good idea to take einstein's advice.

the 4th choice is definitely so wrong that is likely the single answer of this question
