Answer: A) the influence of the press on popular opinion.
Explanation:
The Spanish–American War (1898) was the first time a military action was accelerated by the involvement of the press. Several American newspapers purposefully grew the public interest in the war by inventing stories that favored the intervention in several Spanish colonies all around the world.
This changed the history of propaganda by starting the political use of yellow journalism.
