Poor intellectual property laws hindered foreign countries during the industrial revolution by (a) increasing labor costs (b) allowing the u. s. to increase production (c) decreasing exports (d) encouraging people to buy goods produced in the u. s.

The correct answer here is, in fact, B: allowing the U.S. to increase production.

Explanation:

The establishment of patents, and especially intellectual property laws, known as IPR´s, for science and technology products began during the Industrial Revolution in response to the increase in techological and scientific discoveries and creation especially in the countries of the first world. Especially the U.S began imposing laws that regulated these patents and intellectual property laws in favor of the products generated in the U.S, over those of less developed countries. In recent studies it has been found that IPR´s are directly related with per capita income and show the particular strength and development of a country as it shows the link between human intellect and knowledge, especially linked to educational levels. This link has been shown more strongly in advanced countries and it happened during the Industrial Revolution.
