Student A:Context: In April 2005, the show was revised slightly. Aside from numerous tweakings to the script, there are slight differences in the revised version's musical numbers. Chief among these is a brand new song opening Act II called "Still Rockin."' Other changes include the removal of the' rap' "Dancing is not a Crime". Only the very first section of the rap is used and right before "Mama Says" instead of during the Town Council meeting. Ren gives a speech instead during the meeting. Also, the Reverend's song "I Confess" has also been removed and replaced with a much longer and more emotional scene with Ren after the Town Council meeting and a short reprise of "Heaven Help Me" sung by Reverend Moore alone. Furthermore, the show now begins with Rusty, Wendy Jo, and Urleen singing the opening of "Footloose" instead of Ren and the boys, and during "Learning to be Silent" Ariel sings with Vi and Ethel during the song.

Student A:Passage: Between 1882 and 1886 Schuyler Wheeler invented a fan powered by electricity. It was commercially marketed by the American firm Crocker & Curtis electric motor company. In 1882, Philip Diehl developed the world's first electric ceiling fan. During this intense period of innovation, fans powered by alcohol, oil, or kerosene were common around the turn of the 20th century. In 1909, KDK of Japan pioneered the invention of mass-produced electric fans for home use. In the 1920s, industrial advances allowed steel fans to be mass-produced in different shapes, bringing fan prices down and allowing more homeowners to afford them. In the 1930s, the first art deco fan (the "swan fan") was designed. By the 1940s, Crompton Greaves of India became the world's largest manufacturer of electric ceiling fans mainly for sale in India, Asia and the Middle East. By the 1950s, table and stand fans were manufactured in colors that were bright and eye catching.
