The correct answer is: "allowing goods to be shipped further".
The spread of the internal combustion engine allowed to developed faster means of transport with great capacity, which enabled to transport large amounts of goods at a low cost. Companies were able to cheaply transport their products to further places, therefore the markets where they could operate widened significantly. A progressive market integration process took place as technologies allowed the development of more efficient production and transportation systems.
