Question

how did the development of the bessemer process affect the growth of cities?
it enabled the mass production of steel, which was used to build new factories.
it enabled the mass production of steel, which was used to build new universities.
it led to the invention of electricity, which supported expanding factories.
it led to the invention of the telegraph, which made business communications more efficient.

Explanation:

The Bessemer process was a breakthrough for mass-producing low-cost, high-quality steel. This steel was critical for constructing large industrial factories, which drew workers from rural areas to cities, driving urban growth. The other options are incorrect: steel was not primarily used for university construction in this context, the Bessemer process did not lead to electricity or the telegraph (those were separate innovations).

Answer:

A. It enabled the mass production of steel, which was used to build new factories.
