About the article "Andy Warhol", section "Early life (1928–1949)".

Candidate passages:
"La Dolce Viva" is an interview story with "superstar" Viva, who is one of the many actresses in Andy Warhol's movies.
Yet Viva, was headlined as 'The Last of Andy Warhol's "superstars".'
Warhol would simply film them, and declare them "superstars".
Along with being an actresses, Viva is a model who influences the fashion trends of the time.
Viva's modeling and acting career was launched with the help of Andy Warhol and his many friends.
Being in Andy Warhol's inner circle made Viva the perfect character for this interview.
Viva grew up in a very Catholic home surrounded by figures of the Virgin Mary, Bibles, and pictures of First Communion.
At home, religious values were imposed upon Viva from her family.
Viva lived with the nuns until she was twenty years old.
Once Viva turned twenty, she left the religious ways of her family and the Catholic Church and she started to explore what is now her derogatory lifestyle of sleeping around with multiple partners.
The book details Viva's experience with sex, drug, and love in Warhol's factory.
Along with sleeping with a different guy almost every night, Viva also was turned on to drugs by Timothy Leary.
Viva started doing drugs out of curiosity but quickly became addicted and could not stop.
The environment of Andy Warhol and his inner circle did not help her addiction to these drugs due to the fact that everyone else was using them as well.
Once Viva became tired of drugs and sex, she decided to return home to her parents and asked to be put into a mental institution.
Once viva say the institution, she became scared and begged her mother to take her home.
When Viva returned home, she realized that she missed the lifestyle that she had with Andy Warhol and decided to go back to New York with her sister.
Viva started out back in New York with her sister but that quickly ended when she realized her dependency upon Andy Warhol and she decided to leave her sister and move back into Andy Warhol's inner circle.
Her promiscuous ways and drug use led Viva to become very dependent upon men.
Even though in the interview Viva tries to portray herself as an independent woman, she greatly depends on Andy Warhol to not only help pay her rent and electricity bill but to help her keep up with her lifestyle of drug use and fitting in with the crowd.
Having to have Andy Warhol pay for everything Viva needed clearly shows just how dependent she was on someone else.
