Question

The use of machines had what impact on production of goods? A revolution of production had begun. More goods could be produced in a short amount of time. People wanted machines in their homes. Machines made working by hand highly profitable.

Answer 1

Although (A revolution) is correct, it DOES NOT fit for the question that is asked because they want to know what impact machines had on PRODUCING goods.

More goods could be produced in a short amount of time (would be the best answer because it directly answers the question on how machines impact the production of goods...machines make it possible to create more goods/products in a shorter amount of time than could be made by hand).

People wanted machines in their home DOES NOT answer the question and is completely irrelevant. It is an opinion rather than an answer to the question. It makes no sense, so you can cross that one off.

Machines made working by hand highly profitable. Also DOES NOT answer the question. If anything, the use of machines weeded out the production of products by hand. For example: Why wait two weeks for a shoe maker to make your shoes when you could go to a store that has a pair of shoes already in stock on the shelf that were just delivered from the factory, where a machine made them in less than a day. This all involves supply and demand. The demand for that pair of shoes is high. People what them now, not in two weeks. So again that is not a good answer.

Answer 2

The answer is more goods could be produced in a short amount of time. This was because machines worked much faster than people. This also meant that people's presence would be less significant during production.
