V. Read the following passage and blacken the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions.
Most of the fastening devices used in clothing today, like the shoelace, the button, and the safely pin. have existed in some form in various cultures for thousands of years. But the zipper was the brainchild of one American inventor, namely Whitcomb Judson of Chicago. At the end of the 19th century. Judson was already a successful inventor, with a dozen patents to his credit for mechanical items such as improvements to motors and railroad braking system.
He then turned his mind to create a replacement for the lengthy shoelaces which were then used in both men’s and women's boots. On August 29th 1893, he won another patent, for what he called the case “locker”. Though the model was somewhat clumsy, and frequently jammed, it did work: in fact, Judson and his business associate Lewis Walker had sewn the device into their own boots. Although Judson displayed his clasp-locker at the World's Fair held in Chicago in 1893, the public largely ignored it. The company founded by Judson and Walker, Universal Fastener, despite further refinements, never really succeeded in marketing the device.
The earliest zip fasteners were being used in the clothing industry by 1905, but it was only in 1913, after a Swedish-American engineer, Gideon Sundbach, had remodeled Judson's fastener into a more streamlined and reliable form, that the zipper was a success. The US Army applied zippers to the clothing and equipment of the troops of World War I. By the late 1920s, zippers could be found in all kinds of clothing, footwear, and carrying cases; by the mid-1930s, zippers had even been embraced by the fashion industry.
The term “zipper" was coined as onomatopoeia (resembling the sound it makes) by B.F. Goodrich whose company started marketing rubber shoes featuring the fastener in 1923. Regrettably. Whitcomb Judson died in 1909, and never heard the term, or saw the success by which his invention would become popular.

Part 11: Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions
People are often surprised to learn just how long some varieties of trees can live. If asked to estimate the age of the oldest living trees on Earth, they often come up with guesses in the neighborhood of two or perhaps three hundred years. The real answer is considerably larger than that, more than five thousand years.
The tree that wins the prize for its considerable maturity is the bristlecone pine of California. This venerable pine predates wonders of the ancient world such as the pyramids of Egypt, the Hanging Gardens of Babylon, and the Colossus of Rhodes. It is not nearly as tall as the giant redwood that is also found in California, and in fact it is actually not very tall compared with many other trees, often little more than five meters in height. This relatively short height may be one of the factors that aid the bristlecone pine living to a ripe old age-high winds and inclement weather cannot easily reach the shorter trees and cause damage. An additional factor that contributes to the long life of the bristlecone pine is that this type of tree has a high percentage of resin, which prevents rot from developing in the tree trunk and branches.
