第10至20題為選組 The five-pointed star drawn with five lines is known today as the pentagram. It is an ancient symbol which has held different meanings. Today, we can see the pentagram 16. as jewelry or designs on clothing. The Sumerians were the first to use the five-pointed star polygon. They wrote about the symbol in records 17. 3000 B.C. In the context of that civilization, the pentagram was a character in a writing system. The Babylonians, a culture with close historical links to Sumer, used the pentagram 18. the planets. Its five points indicated five planets - Mercury, Venus, Mars, Jupiter, and Saturn. In ancient China, the pentagram corresponded to Wu Xing, the five elements that make up the world: metal, wood, fire, earth, and water. In European folklore, it was said to come with magical properties. The 19. of the star affected its significance. With one point facing upward, the pentagram represented "white" magic (good). 20. with two points facing upward, the same symbol stood for "black" magic (evil). Nowadays the symbolism of the pentagram is still commonly used, but it is good to know more of its history than just a fashion statement. 16, (A) wearing 17.

Problem 3 Creating a 0.1 Normal Solution Suppose you must determine the amount of hydrogen halides (HCI, HBr and HF) in the flue gas leaving a chemical reactor. The emission sampling train for hydrogen halide determination calls for a total of 200 mL of 0.1 N H₂SO4 as an absorbing solution. The absorbing solution will be located on the impingers of the sampling train. How many grams of H₂SO4 should be added to water to create 200 mL of a 0.1 N H₂SO4 solution? > The chemical reaction of H₂O and H₂SO4 is as follows: H₂SO4+H₂O 2H++SO₁²+H₂O 4 > Approximate atomic weights of elements: H=1, S=32, O=16

Since 1968, students in Taiwan have had nine-year compulsory education, 16. 6 years of elementary school and 3 years of junior high school. Children at least six years of age are required to begin primary schooling without taking entrance tests. After finishing compulsory education, students take another set of exams to 17. for different senior high and vocational schools. Various administrations have discussed the possibility of offering 12-year compulsory education since 1983. 18. previous plans never got off the ground due to high costs and opposition from almost all circles of the society. Currently, 19. improve national competitiveness, Taiwan will extend compulsory education from 9 to 12 years starting in 2014. When the plan to lengthen compulsory education is fully implemented, students will be able to gain admission to the vast majority of high schools without taking an entrance exam.
