Cleaner Abundant Reading Answer Passage

 

Paragraph A. For many years, the crop circle phenomenon has perplexed and confused humanity. The drawings emerge out of nowhere, meticulously arranged among fields of food grains. Some are the size of football fields and are extremely difficult to design and construct. Others are more rudimentary and smaller. Crop circles are what we call them, yet most of them aren't circular. Some are extended abstract designs, some mimic insects or other known forms, while still others are complex patterns made up of lines, circles, and other shapes. The majority appear overnight, while it has been claimed that a handful has appeared in broad daylight within a half-hour.

 

Paragraph B. Crop circles have been spotted all around the globe. In recent years, approximately 10,000 cases from various nations have been documented. In December of 1973, the first crop circles occurred in Australia. In a wheat field in Wokurna, a town southeast of Adelaide, a weird circular mark formed. In an adjacent outfield, seven swirled circles up to 14 feet in diameter appeared. An astonishing series of circles, varying in diameter from a few inches to a few feet, formed in a wheat field west of Melbourne in December 1989. A total of 90 crop circles were discovered.

 

Paragraph C. During the summer of 1980, the best-documented and greatest modern spread of crop circles began in southern England. By the end of 1988, 112 circles had been established. At the time, 305 circles had been reported worldwide, with a total of 305 by the end of 1989. In 1990, the total number of newly established circles surpassed 1,000. There were 200 to 300 circles reported in 1991. Crop circles have been discovered in over 30 nations, including Canada, the former Soviet Union, Japan, and the United States of America. The stalks around the rings stayed entirely erect in nine out of ten circles, while damaged stems flattened to the ground and swirled.

 

Paragraph D. Crop circles, over time, have become far more mathematically complicated. Multiple circles, bars, triangles, rings, and spurs were used in the patterns. There were also pictorial images. While on an early morning walk in the countryside, eyewitnesses reported seeing strange lights and hearing unidentified sounds. Later that day, a crop circle appeared. At the site of some crop circles, high-pitched warbling noises have been recorded. A peculiar glow or darker colouration has been spotted in the sky around a crop circle on multiple occasions. In several instances, the electrical power of small planes flying overhead has shut off suddenly. Interestingly, these energies do not appear to harm animals or insects.

 

Paragraph E. Crop circles have sparked a lot of interest among scientists, who have spent years studying them. They look for signs of human involvement in the circle-making process, examine the area for geographical anomalies, and compare the grain inside and outside the circles for differences. Many grain samples have been studied by Dr. W.C. Levengood of BLT Research in Cambridge, Massachusetts, who confirmed dramatic alterations at the cellular level of crop circle plants. Elongated cells and blown-out nodes are common. Seeds from circular plants often demonstrate accelerated growth and differ in appearance. Vortex-like energy seems to flatten the plants, though they continue to grow normally after the circle appears.

 

Paragraph F. Several researchers have also discovered soil and environmental anomalies within crop circle sites. Duke University's Micheal Corost identified short-lived radionuclides in the topsoil layer. A British government laboratory discovered lower nitrogen levels, a lower nematode population, and reduced water content in the soil. Other abnormalities include embedded magnetic particles, burnt plant tissues, and stalks that appear to have been rapidly heated by microwaves. Some scientists have tried to explain crop circles through natural phenomena. 

 

Paragraph G. The widely accepted 'Plasma Vortex Notion,' proposed by Dr. Terence Mearden, suggests that electrified air forms micro tornados that create the circles. This theory also explains the lights reported above crop circles. However, this theory has been questioned due to the increasingly elaborate crop circle patterns seen since 1991. Another theory claims all crop circles are hoaxes, but this seems unlikely, as many circles appeared long before the phenomenon gained public attention and often reveal complex mathematical patterns upon investigation.

1. Wind

 

Reference: From paragraph A: "The renewable energy captured from wind, sun, global warming, waves, and small dams is drawing record amounts of investment as poor villagers and whole nations are looking for clean, abundant manners to stimulate economic growth."

 

Explanation: This line lists "wind" as one of the renewable energy sources gaining attention and investment. Since the question is about identifying a type of renewable energy mentioned in the passage, "wind" is the correct answer, as directly stated in this sentence.

 

2. 2004

 

Reference: From paragraph A: "According to a new report by the Renewable Energy Policy Network (REN21) for the 21st century, global investment in renewable energy set a new record of $ 30 billion in 2004."

 

Explanation: The sentence clearly states that the record investment in renewable energy occurred in the year “2004”. This directly answers the question asking for the specific year when global investment peaked at $30 billion.

 

3. Business

 

Reference: From paragraph B: "Eric Martino said "Renewable energy has become big business," lead author of the study, "Renewables 2005: Global Status Report."

 

Explanation: This quote highlights how renewable energy has transformed into a significant and growing industry. The word "business" is explicitly used to describe the scale and importance of the sector, making it the correct answer.

 

4. Solar

 

Reference: From paragraph B: "The report counts that nearly 40 million households around the world heat their water through solar collectors, most of which have been installed in the past five years."

 

Explanation: The line shows that a large number of households use "solar collectors" for heating water, indicating the widespread use of solar energy. The mention of "solar" in this context directly supports it as the correct answer.

 

5. 1.7

 

Reference: From Paragraph B: “Overall, the renewable energy industry employs 1.7 million people, and most of them are proficient and nicely paid.''

 

Explanation: This line provides the exact number of people employed in the renewable energy industry—1.7 million. Since the question is asking about employment figures, this statistic makes "1.7" the accurate answer.
