Trends in Fashion History (1)    It is hard to imagine, but in the early 1900s, most people were shocked by skirts that showed women’s ankles. By the early 1970s, however, most people completely accepted the miniskirt, which showed almost all of a woman’s leg. What caused this change? Trends in fashion, which often arise out of social protest movements, can deeply affect what people consider to be appropriate. (2)    One well-known example is the rise in popularity of the denim jean, which, until the mid-20th century, was connected with the “working man” and was not accepted in either business or social situations. In the 1950s, many young people began wearing jeans because they wanted to identify with everyday workers rather than office workers who typically wore dark suits with white shirts. During the 1960s, Vietnam War protesters and others who were working to change American society wore jeans as a sign of being “antiestablishment.” They did not agree with the policies of the government and did not want to look like government workers who usually wore conservative suits. Throughout the 1970s, this trend of wearing jeans continued, and, by the 1980s, denim had become accepted by many people. Office workers began to wear jeans with blazers and button-down shirts at work on Fridays. This trend became known as “business casual,” and jeans, which were once a symbol of protest, became part of our everyday fashion. (3)    Another trend in fashion that came from the punk rock movement in the 1970s was the wearing of second-hand clothing. This type of clothing was often older, from another era, and may have had holes or ripped seams. This trend began in part as a reaction to rock super groups who had complicated stage shows and wore expensive costumes. In contrast, punk bands played on simple stages, did not really know how to play their instruments, and wore clothes that often needed to be held together with safety pins because they were so badly damaged and used. Soon, the public began to realize that second-hand stores, often called thrift stores, had many interesting pieces of clothing from the 1920s, 30s, 40s, 50s and 60s which often were sold at very low prices, sometimes for even less that one dollar. From this, the “vintage clothing” industry was born, and today, fashion-conscious people often wear clothes that are older and are second-hand. Indeed, some current clothing manufacturers have begun to make new copies of clothing that were originally found in thrift stores. The prices, of course, are much higher than one dollar, but this “vintage” look can claim its beginning in the clothing of the mid-70s punks. (4)    What will be the fashion trends of tomorrow? Will we still wear miniskirts, jeans or vintage clothing? Or will new items emerge as other social protests arise? These trends are difficult to predict but are very interesting to watch as they become part of what we wear every day. What is the topic of the passage “Trends in Fashion History”?

What figurative language is used in “The first chime sang out across the hills.”?

A homeostatic system generally has three components: a receptor, an effector, and a control center.  In the example given below, determine which is acting as the effector: When a person has not taken in sufficient water, they become dehydrated.  This may cause a loss of blood pressure which is detected by structures known as baroreceptors in the blood vessels.  The baroreceptors communicate with the brain, telling it to release a chemical known as antidiuretic hormone.  This hormone signals the kidney to decrease the amount of urine produced so that more water stays in the blood, helping to bring the blood pressure back up to normal levels.

Calcitonin and parathyroid hormone are both produced by the parathyroid gland.
