It is pointed out in the passage that Steinbeck's novels ----.

John Steinbeck was born in California in 1902. He
studied literature and writing at Stanford
University for six years but, for financial reasons
had to leave. He then moved to New York City
where he worked as a labourer and journalist for
five years. From there he moved back to
California. In 1935, with the publication of Tortilla
Flat, a collection of humorous stories, Steinbeck
finally achieved popular success and financial
security. He then moved on to write more serious
fiction. Steinbeck's novels can all be classified as
social novels dealing with the economic problems
of rural labour. In 1939 he published what is
considered his best work, The Grapes of Wrath,
the story of Oklahoma tenant farmers who, unable
to earn a living from the land, moved to California
where they became migratory workers.
