In 1978, she dropped out of college and relocated to New York City. She had little money and worked as a waitress at Dunkin' Donuts and with modern dance troupes, taking classes at the Alvin Ailey American Dance Theater and eventually performing with Pear Lang Dance Theater. Madonna said of her move to New York, "It was the first time I'd ever taken a plane, the first time I'd ever gotten a taxi cab. I came here with $35 in my pocket. It was the bravest thing I'd ever done." She started to work as a backup dancer for other established artists. Madonna claimed that during a late night she was returning from a rehearsal, when a pair of men held her at knifepoint and forced her to perform fellatio. Madonna later commented that "the episode was a taste of my weakness, it showed me that I still could not save myself in spite of all the strong-girl show. I could never forget it."
What did she also work as for other established artists?

The role of the gas is to prevent evaporation of the filament, without introducing significant heat losses. For these properties, chemical inertness and high atomic or molecular weight is desirable. The presence of gas molecules knocks the liberated tungsten atoms back to the filament, reducing its evaporation and allowing it to be operated at higher temperature without reducing its life (or, for operating at the same temperature, prolongs the filament life). It however introduces heat losses (and therefore efficiency loss) from the filament, by heat conduction and heat convection.
What is a potential problem with the use of gas in a light bulb?
A: introduces heat losses (and therefore efficiency loss)

Twilight Princess takes place several centuries after Ocarina of Time and Majora's Mask, and begins with a youth named Link who is working as a ranch hand in Ordon Village. One day, the village is attacked by Bulblins, who carry off the village's children with Link in pursuit before he encounters a wall of Twilight. A Shadow Beast pulls him beyond the wall into the Realm of Twilight, where he is transformed into a wolf and imprisoned. Link is soon freed by an imp-like Twilight being named Midna, who dislikes Link but agrees to help him if he obeys her unconditionally. She guides him to Princess Zelda. Zelda explains that Zant, the King of the Twilight, has stolen the light from three of the four Light Spirits and conquered Hyrule. In order to save Hyrule, Link must first restore the Light Spirits by entering the Twilight-covered areas and, as a wolf, recover the Spirits' lost light. He must do this by collecting the multiple "Tears of Light"; once all the Tears of Light are collected for one area, he restores that area's Light Spirit. As he restores them, the Light Spirits return Link to his Hylian form.
What is the Light Spirits job at the start of Twilight Princess?
