Question 28: A. personality B. intelligence C. interest D. response
Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct option that best fits each of the numbered blanks from 29 to 33.
The movement of ocean waters as the tides rise and fall is what produces tidal energy. One sustainable energy option is tidal power.
Engineers in the 20th century found ways to harness the power of the tides in places with a large tidal range, or areas that change from high tide to low tide. To harness the power of the tides, each technique employs specialized generators.
The development of tidal energy sources is a relatively new field. There hasn't been much power generated thus far. There is a severe lack of commercial-scale tidal power plants globally. La Rance, France was the site of the first. The tallest building is the South Korean Sihwa Lake Tidal Power Station. There are very few locations in the US where tidal energy could be economically produced, and none of the country's tidal plants are operational. This energy source has considerably more potential for usage in Russia, China, France, and England than in any other country.
Concerns regarding the ownership of underwater land and its potential environmental impact have prompted legal proceedings in the US. Since there is no solid assurance that tidal energy will generate profits or benefit consumers, investors are not very excited about it. To make tidal energy generators more profitable for energy companies while simultaneously reducing their environmental effect, engineers are constantly innovating new ways to harness the power of the tides.
