Answer: They were overly dramatic.
Step-by-step explanation:
When the word lurid is used, it implies that something is sensational or shocking and in reference to newspapers of the ''yellow journalism'' era, it would imply newspapers that used overly dramatic headlines to get people to notice their newspapers.
The era of Yellow journalism worked by newspapers presenting news that exaggerated the facts or even spreading simple rumours by using lurid headlines to draw people in so that they would buy the papers.
