Read the following passage and answer the questions below.

Leonardo DiCaprio is an American actor, film producer, and environmentalist. He has played unconventional roles, usually in biopics and period
films. As of 2019, his films have grossed $7.2 billion worldwide, and he placed eight times in annual rankings of the world's highest-paid actors.
Born in Los Angeles, DiCaprio began his career by appearing in television commercials in the late 1980s. In the early 1990s, he had recurring
roles in various television shows, such as the sitcom Parenthood. DiCaprio had his first major film role as Tobias "Toby" Wolff in This Boy's Life
(1993).

At age 19, he received critical acclaim and first Academy Award and Golden Globe Award nominations for Best Actor in a Supporting Role for
his performance as a developmentally disabled boy Arnie Grape in What's Eating Gilbert Grape (1993), becoming the seventh-youngest nominee
in the category. He achieved international stardom in the epic romance Titanic (1997), which became the highest-grossing film to that point.
After a few commercially unsuccessful films, DiCaprio starred in two successful features in 2002: the biographical crime drama Catch Me If You
Can and the historical drama Gangs of New York, which marked his first of many collaborations with director Martin Scorsese.

DiCaprio portrayed Howard Hughes in The Aviator (2004) and continued to receive acclaim for his performances in the political thriller Blood
Diamond (2006), the crime drama The Departed (2006), and the romantic drama Revolutionary Road (2008). In the 2010s, he starred in the
science fiction thriller Inception (2010), the western Django Unchained (2012), the biopic The Wolf of Wall Street (2013), the survival drama
The Revenant (2015), and the comedy-drama Once Upon a Time in Hollywood (2019), all of which were critical and commercial successes. His
accolades include an Academy Award, a BAFTA, Screen Actors Guild Award, and a Golden Globe Award for The Revenant as well as two other
Golden Globes for The Aviator and The Wolf of Wall Street.
