Read the text about Betty Grable and answer the questions.
Ruth Elizabeth "Betty" Grable (December 18, 1916 - July 3, 1973) was an American actress, singer and pin-up girl, whose famous bathing suit poster was an icon of the World War II era. Born in Saint Louis, Missouri, she was propelled into acting by her mother, who insisted that one of her daughters become a star. For her first role, as a chorus girl in the film Let's Go Places (1930) Grable was legally under the age to act, but because the chorus line performed in blackface, it was impossible to tell how old she was. For her next film, her mother tried to get her to sign a contract using false I.D., but when this was discovered, she was fired. It was at this time that she was photographed in the pin-up poster that was so popular among American GIs ten years later.
