想請問下方兩題, 16.主要是不知道as在那裡的作用(因為as看很久還是錯了),以及為什麼要使用被動 17.是覺得四個都可以🥲 非常感謝!!

13. (A) if 14. (A) helps 15. (A) Unfortunately 第16.至20.題為題組 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 (B) worn 17.
