Explanation:

To support the statement about a law aiding magazine companies, we look for text about a law impacting their business. The sentence "This was a boom time for magazine publishing, owing in part to developments in offset printing technology as well as to the Postal Act of 1879, which had granted magazines discounted mailing rates" directly links the Postal Act of 1879 (a law) to easier business for magazines via discounted mailing rates. Other parts talk about short stories' popularity or sales, not the law's impact.

Answer:

This was a boom time for magazine publishing, owing in part to developments in offset printing technology as well as to the Postal Act of 1879, which had granted magazines discounted mailing rates.
