The following text is adapted from Oscar Wilde's 1891 novel The Picture of Dorian Gray. Dorian Gray is taking his first look at a portrait that Hallward has painted of him.

Dorian passed listlessly in front of his picture and turned towards it. When he saw it he drew back, and his cheeks flushed for a moment with pleasure. A look of joy came into his eyes, as if he had recognized himself for the first time. He stood there motionless and in wonder, dimly conscious that Hallward was speaking to him, but not catching the meaning of his words. The sense of his own beauty came on him like a revelation. He had never felt it before.

For thousands of years, people in the Americas ______ the bottle gourd, a large bitter fruit with a thick rind, to make bottles, other types of containers, and even musical instruments.

According to historian Vicki L. Ruiz, Mexican American women made crucial contributions to the labor movement during World War II. At the time, food processing companies entered into contracts to supply United States armed forces with canned goods. Increased production quotas conferred greater bargaining power on the companies' employees, many of whom were Mexican American women: employees insisted on more favorable benefits, and employers, who were anxious to fulfill the contracts, complied. Thus, labor activism became a platform for Mexican American women to assert their agency.

Because modern-day composite filming techniques such as blue screen did not yet exist, let alone computer-generated special effects, director Harold Lloyd had to be creative with his stunts. He used a full-scale replica of two floors of Los Angeles's International Savings Building and set them on the roofs of progressively taller buildings: that is, he placed the replica on a platform atop a two-story building, then a seven-story building, then a thirteen-story building. The trick allowed Lloyd to climb only a few stories at a time while always perpetuating the illusion that he was climbing several stories higher.
