How do the headlines sell newspaper

Headlines have the best story/stories they r made to catch people’s eyes to get them to buy them so they they have the story that everyone wants to see up in bold letters or something so they will notice it

the group i'm selecting: greeks.

a first group of greek immigrants came to the us in the 1850s. the second group came to america starting in the 1890s due to economic opportunities they didn't have back in their home caused by the hardships of ottoman rule. greek immigration was 90% male, many of them expected to work and return to greece after earning enough capital, but ultimately had to remain in the us after the greek genocide.
