Answer:
Nick answered a long-distance call about Gatsby's criminal business.
Step-by-step explanation:
The novel "The Great Gatsby" was written by American author F. Scott Fitzgerald. The story is narrated by Nick, who gets involved with Gatsby due to his being Daisy's cousin. Jay Gatsby has been in love with Daisy for many years, and has gone from poor to millionaire in an effort to conquer her back and offer her the life he thinks she deserves.
Throughout the book, Gatsby throws grand parties that are attended by all sorts of people, none of them really acquainted with him. They are simply strangers who enjoy drinking and eating for free while, at the same time, whispering all types of gossip about Gatsby's past and how he made his fortune.
In the end, when Gatsby ends up killed, Nick is the only person by his side. When the phone rings, Nick picks it up thinking it might be Daisy. To his surprise, it is one of Gatsby's shady partners. It turns out people weren't completely wrong in their rumors about him. Gatsby was indeed a bootlegger and the long-distance calls Nick saw him answer before concerned his criminal business. Gatsby sold illegal liquor and traded stolen securities.
