A Bit About Bicycles: Children begin to taste freedom on bicycles. Historians believe that bicycles began around 3500 B.C. in the Middle East although it took 53 centuries before bicycles were fashioned in the way we know them today.
With over 1500 moving parts, bicycles are complex yet simple machines and amazingly the basic design has not changed since the 1880s. A few tweaks have been added, such as gears and hand-operated brakes, but bicycles remain a steady source of exercise and entertainment for both children and adults. Some forms of bicycling are mountain biking and BMX biking which is similar to cross-country motorcycle racing.
In many countries around the world, bicycles are a necessary part of daily existence. Bicycling in China is imperative if you want to go places, due to the vast population in a relatively small area. Bicycles are coming back in high demand all over the world.
After reading this article, the reader learns that
- A. bicycles break down because of the moving parts.
- B. bicycles are only found in China.
- C. bicycling is gaining in popularity all over the world.
- D. BMX bicycling is dangerous.

About 6% of the earth is covered by rainforests. The largest rainforest in the world is the
Amazon Basin, which stretches over 2.3 million square miles in nine different South American countries. This area is double the length of all the other remaining rainforests in the world. Brazil contains 60%of the Amazonian rainforest, since it lies at the mouth of the river Amazon. This river is the second largest in the world and contains more than one-fifth of the world's fresh water. The Amazon rainforest is a type of wet broadleaf forest. The weather there is very humid and warm as it rains quite a bit. Because of the high rainfall, the forest is very rich and green. The
tree leaves are pointed and narrow so that the raindrops can easily drop off wet plants. This
tropical rainforest has more living species than the entire European continent. There are over 400 types of insects living in one single rain forest tree for a total of 2.5 million species. One square kilometer of rainforest may contain over 75,000 types of trees and approximately 438,000
different kinds of plants, which comes to a total of 90,000 tons of greenery overall. The Amazon rainforest is home to 2,000 birds and mammals, with one in every five birds in the world living there. Local farmers have lived off this rich and diverse land for thousands of years. They have been able to find food and water here without destroying the land. The Kayapo people of Brazil
farm in an environmentally-friendly way. Instead of chemicals, they use burned wood to enrich the soil, and plant banana trees, which attract wasps. These wasps then feed on leafcutter ants and get rid of these harmful insects. The rainforest also offers a lot of tropical fruits, such as bananas and coconuts, as food.
Cinnamon is made from the bark of a rainforest tree. Amazonian Indians use the fruit and stem
of the Buruti plant as a drink, to make bread and to build houses. Many other plants are used as medicine. But the Amazon rainforest is in very big danger of disappearing. 9,169 square miles of
forest have been cut down in 2003 in Brazil alone. An area of the size of a football field is burned down basically every minute, which means that the rain forest may be gone by the year 2030.The dangers related to this type of activity are obvious. Trees take in poisonous carbon
dioxide from the air and give off oxygen. There is more oxygen and less carbon dioxide around a
rainforest. When trees are cut down, however, the amount of carbon dioxide increases, and the
air gets warmer. This leads to global warming, which is extremely harmful to the environment. It
is estimated that the burning of Brazilian rainforests alone produces 200 million metric tons of carbon dioxide ayear. Another danger connected with destroying the rainforest is the disappearance of plants and animals. When trees are cut down, plants and animals have no more
food left and slowly die out. Killing wild animals is illegal in Brazil, but there is plenty of stealing going on. 38 million animals are stolen and sold illegally each year. The most hunted
animals are birds, especially parrots, followed by snakes and the jaguar.
How can you describe the Amazon rainforest?
- A. It rains all the time there, so the forest is always green.
- B. The weather is so hot that not many tourists come to visit.
- C. The plants are shaped so that rainwater can pour off them.
- D. There is a lot of fresh water coming from the Amazon River.
Correct Answer: A
Rationale: The correct answer is A. The Amazon rainforest is characterized by high rainfall, which keeps the forest lush and green. The text mentions that the weather is very humid and warm due to frequent rain, leading to a rich and green forest. Additionally, it describes how the tree leaves are shaped to allow raindrops to easily fall off wet plants, highlighting the adaptation to the high rainfall in the region.
Subjective exams measure your ability in several areas. Besides recall information, you must be
able to realize content logically and intelligently express yourself in a clearly understood manner. Subjective test provide opportunity for students to show their broad knowledge of a subjective
area. Answers may be in the form of paragraphs or lengthy essays. When your review for an essay exam, concentrate on main ideas rather than details. Since essay tests are less to a few questions, they are likely to deal with more important ideas of a subject. Prepare a list of question you think might be asked. Write an answer to each of your questions. Rather than writing complete sentence down your thoughts in outline form. Doing so will help
you organize the information so that you can express yourself clearly.
When you take the test, read through all the questions before you start to write. Allot time for each question, spending more time for questions worth the most points. Read each question carefully to determine exactly what they are asked. Pay attention to words such as define, illustrate, explain, list, compare, and contrast. Each work requires a different type of response. Write a brief outline of your answer on scrap paper or the back of the test. Make sure you include all the important ideas that are within the limits of the question. In other words, do not write more than is asked for each answer. When you write your answer, keep it specific and as brief as possible. In the introductory sentence it is often helpful to make a general statement that includes
important points addressed in each question. Such a topic sentence serves as a framework for your answer. Then use your outline to develop the main point and subtopics. Add substance to
your answer by including as many facts as possible to support your answer.
Check your paper before you submit it. Look for mistakes in grammar, spelling, sentence
structure, and punctuation. Unless you are certain an answer is wrong, do not change it. Your answer is an educated guess and is usually your best chance of answering correctly.
From the article, the reader can conclude that a test containing true-false questions is called what?
- A. Subjective
- B. Rejective
- C. Objective
- D. Detective
Correct Answer: C
Rationale: The correct answer is C: 'Objective.' The article distinguishes between subjective and objective tests. Objective tests, such as those containing true-false questions, have definitive answers that are either true or false. These questions are considered objective because they are not open to interpretation and are designed to measure specific knowledge or facts. On the other hand, subjective tests, as mentioned in the article, involve essay questions where responses are more interpretive and open-ended. Therefore, based on the information provided, the appropriate term for a test containing true-false questions is 'Objective.'
Have you ever found yourself staring at the ceiling at 2:00 a.m.? Have you kicked the blankets off to the floor from tossing and turning? Many longtime suffers of Insomnia know these situations all too well. As many as 17% of Americans find the restful break of sleep hard to achieve.
Lack of sleep affects intellectual abilities at work or school by causing a deficit in memory, attention, and concentration which in turn creates a feeling of irritation or depression. Chronic insomnia can result from a medical illness, a psychiatric condition, or from sleep apnea, a condition where an individual actually stops breathing during sleep. Sleep hygiene, developing good sleep habits, and non- pharmacological therapies such as herbs and spices are some solutions to Insomnia.
What can sleep apnea cause?
- A. Chronic insomnia
- B. Improved sleep quality
- C. Healthy diet prevents sleep disorders
- D. Insomnia is always caused by stress
Correct Answer: A
Rationale: Sleep apnea can cause chronic insomnia. Sleep apnea is a condition where an individual stops breathing during sleep, leading to disruptions in sleep patterns which can result in chronic insomnia. Chronic insomnia is a sleep disorder characterized by difficulty falling and staying asleep over a prolonged period, often leading to various health issues. Therefore, the correct answer is option A, as sleep apnea is a known factor that can contribute to the development of chronic insomnia.
What effect does your voice have on others? Does it persuade or irritate, attract or repel? One of
the worst qualities is harshness. If you ever get the feeling that people are uncomfortable when you speak, it may be that your harsh tones are jarring their eardrums. Your voice will sound
unpleasant if it is shrill, grating, hard, piercing, brassy, to loud, or too nasal. Harsh voice qualities usually come from too much tension in the throat and jaw. Tension tightens muscles and blocks the relaxed voice tones essential to a pleasing impression. Because tension occurs in higher pitched voices, women tend to have shriller voices than men, which usually makes them
less desirable public speakers, newscasters, or political candidates.
The author seems to
- A. prefer low-pitched tones.
- B. have no particular reactions to different voices.
- C. prefer shrill, grating, and brassy voices.
- D. be an experienced public speaker.
Correct Answer: A
Rationale: The passage indicates that harsh qualities in voices, such as being shrill, grating, or brassy, are undesirable and that they can lead to discomfort for listeners. The author emphasizes that relaxed voice tones are essential for a pleasing impression, suggesting a preference for lower-pitched tones that are more pleasant to hear. Therefore, the most appropriate answer is A, indicating a preference for low-pitched tones.
Glass
I wonder who first discovered glass. This commodity has been a part of civilization from the very beginning. Imagine a world without glass! How dark and dismal it would be. No windows, corrective lenses, telescopes, microscopes, cameras, sparkly drinking containers or mirrors. Life would not be the same without this wonderful discovery. Thank you, whoever found glass!
Glass is not an element, but a combination of several elements. It is a hard, brittle, transparent solid material composed mainly of silica, with additives to change the character of the glass. Common additives are soda, lime, lead, and boron. Each additive changes the properties of the final product. Soda and lime are the most common additives, accounting for about 90% of glass production. Adding lead increases reflectivity, causing the glass to "sparkle." The addition of boron changes the thermal and electrical properties of glass, allowing cookware that can be used in the oven without shattering.
What statement is a fact stated in the article?
- A. Glass isnÄ€™t an element, but a combination of several elements.
- B. Glass is the most important material in modern technology.
- C. Glass can only be used in decorative items.
- D. Glass is naturally occurring and needs no processing.
Correct Answer: A
Rationale: The correct answer is A: 'Glass isnÄ€™t an element, but a combination of several elements.' This statement is a factual detail mentioned in the article provided. It explains that glass is not an element itself but is made up of various elements like silica, soda, lime, lead, and boron. These additives are used to alter the properties of the glass. The article clearly states that glass is not an element, but rather a composite material. The other options are incorrect based on the information given in the article. Glass is not limited to decorative items, it has various practical uses in technology, and it is not naturally occurring but manufactured through specific processes.
