Explanation:

Yellow journalism is characterized by sensationalized reporting to attract readers. The newspaper headline uses dramatic language like "ENEMY'S SECRET INFERNAL MACHINE" and offers a large reward, aiming to stir emotions and public opinion. This type of reporting was used to build support for the Spanish - American War. Embedded journalism (journalists embedded with military units) wasn't relevant here. Secret alliances are about diplomatic agreements between countries. Submarine warfare is a military tactic. The focus of this newspaper page is on sensational reporting, which is yellow journalism.

Answer:

yellow journalism
