Answer:
"The Grapes of Wrath" is one of John Steinbeck best known, and most popular novels, and it was published in 1939. This novel, does not just narrate the lives of a few people during the Great Depression in the United States, and the experiences in the Dust Bowl, but rather it exposes the difficulties and also gains of the migrant workers during this time.
In order for him to achieve this, Steinbeck began to research about these migrants, and their lives, and he was able to do this first, thanks to the work of a colleague of his, Sanora Babb, who had gathered a lot of research on the matter, but also thanks to Steinbeck´s on work at the San Francisco News. This agency had entrusted Steinbeck with compiling a group of seven articles on migrants during the Great Depression, and they became known as The Harvest Gypsies. It was these, and the information that Steinbeck gathered from Babb´s own work, that gave birth to "The Grapes of Wrath"
