Final answer:
The passage author asserts that sixteenth- or seventeenth-century readers would have found a Hemingway short story laughable due to its quaint writing style and lack of essential details.
Step-by-step explanation:
The passage author asserts that sixteenth- or seventeenth-century readers would have "laughed" at a Hemingway short story because they would have found the writing style quaint and because basic, essential details were missing. Hemingway's writing style was known for its short declarative sentences and lack of detail, which was a departure from the long and intricate sentences of Renaissance literature. Additionally, Hemingway often left out important details about the characters' history, which would have been amiss to the readers of that time.
