Question

in response to problems faced by labor in, unions commonly advocated for
fewer working hours and better pay
antitrust laws
legislation for food inspection
laissez - faire economics

Explanation:

Labor unions aim to improve workers' conditions. Fewer working hours and better pay directly address labor problems like long hours and low wages. Antitrust laws target business monopolies, food inspection legislation is about public health, and laissez - faire economics is hands - off, not pro - labor. So the correct option is the one about fewer working hours and better pay.

Answer:

A. fewer working hours and better pay (assuming the first option is labeled A, if not, the option text "fewer working hours and better pay")
