Which area of the u. s. economy has been most directly harmed by the trend toward outsourcing that began in the late 20th century? agriculture or manufacturing?

Hi. 
Your answer is going to be 
A.) agriculture 
Agriculture has been greatly effected since the beginning of the 20th century. Partly due to WW1 and WW2 thus increasing the product demand and cause price spikes.
Hope this helps! :)
