Why were americans in the 1990s concerned about outsourcing?

B-"Some worried that reducing trade barriers would cause outsourcing to foreign countries, leading to job losses within the United States"

Explanation:

Outsourcing is what we called when a company gets some products or services from an employer outside of the company payroll, they pay him, but they do not get the social benefits or the taxes taken, this is cheaper for companies than having an employee doing that job, when outsourcing became more trend in america in 1990´s internet gave the possibility to outsource to other countries, like india, china and south america, where workers charged considerably less than the american worker, and this could meant loss of jobs for the american people.

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

a) hostility to or prejudice against jews.

b) the holocaust, also referred to as the shoah, was a genocide during world war ii in which nazi germany, aided by its collaborators, systematically murdered approximately 6 million european jews             , around two-thirds of the jewish population of europe, between 1941 and 1945.
