a reduced both production times and costs.

b increased both production times and costs.

c reduced production times but increased costs.

d increased production times but decreased costs.

The correct answer is A. Reduced both production times and costs.

Explanation:

The assembly line is a production technique that involves the division of the production process in different stages. Besides this, in the production line, each worker focuses on only one task or stage of assembling and at the end of the assembly line the product is finished. This technique has multiple advantages that include a reduction in costs because it is not necessary to hire skilled workers that know all the process of production; also, this reduces production times as each worker only needs some seconds or minutes to complete his tasks. Due to this, the use of this production technique during the Industrial Revolution reduced both production time and costs (Option A).

the correct answer is d: "party organizers, volunteers, voters, and elected officials."
