Nurseries: If you thought nurseries were just for babies, well, think again! Being special kinds of farms, nurseries are used to raise plants in mass quantities. Plants, trees, and shrubs are typically grown in nurseries and then sold to farmers and gardeners to plant in homes, businesses, and farms. Most nurseries are found in the more rural parts of the country because much land is required to have a viable nursery. If a nursery sells plants to others, it must obtain a special permit from the local city or county, which keeps the competition fair and does not saturate the market with a large number of nurseries selling similar products.
Also on the grounds of nurseries are greenhouses which are made of glass or plastic panes that protect the plants from weather elements that may harm them and cause them not to grow and develop. The glass panels in greenhouses allow for sunlight to enter and moisture to be trapped inside. This creates a tropical environment which allows orchids and poinsettias to grow. It ensures that vegetables and fruits will grow large, which makes them valuable to farmers.
Nurseries are
- A. Places to care for infants.
- B. Special kinds of farms used to raise plants.
- C. Found only in rural areas.
- D. Used to grow vegetables and fruits.
Correct Answer: B
Rationale: The correct answer is B: Special kinds of farms used to raise plants. The passage explicitly states that nurseries are farms used to raise plants in mass quantities such as plants, trees, and shrubs. This is reinforced by the description of nurseries being special kinds of farms and selling plants to farmers and gardeners.
Choice A is incorrect because nurseries are not places to care for infants, as mentioned in the passage. Choice C is incorrect as nurseries are found in rural parts but not exclusively. Choice D is incorrect as the passage mentions that vegetables and fruits are grown in greenhouses on the grounds of nurseries, but the primary purpose of nurseries is to raise plants in mass quantities.

Lightning Strikes
The old wives' tale of "Lightning never strikes twice" has been proven untrue time and time again. Lightning forms from negative and positive charges within clouds and from the earth below. When these charges react with each other, the air between the cloud and the earth ionizes, which produces a lightning flash. Lightning is actually a series of multiple events consisting of a leader stroke of lightning, followed by as many as 40 smaller strokes of lightning. Being just split seconds apart, these strokes of lightning often reflect off the lining of the clouds.
Lightning rods that extend from above the roof to the ground protect buildings by forming a low resistance path for the lightning so that the lightning does not enter the building, but rather defuses as it penetrates the ground.
Some myths about lightning need to be explained. Lightning does strike tall buildings often, and during a particularly violent storm, a tall building may be hit by lightning several times. The safest place during a thunder and lightning storm is in a metal car or lying flat, face down, in the open, not under a tree as the myth suggests.
Many people believe that thunder and lightning are connected; however, this proves to be true only about 50% of the time, so if you're waiting for the clap of thunder, you're missing out on some exciting strokes of lightning!
Lightning causes injuries, deaths, and forest fires each year. However, some scientists reveal the positive aspects of lightning because it releases nitrogen into the atmosphere which the raindrops then deliver to earth to fertilize our soil.
When taking cover from lightning, you should:
- A. Stand under a tree for protection
- B. Seek shelter in a wooden building
- C. Get into a metal car, or lie flat on the ground
- D. Stay outside and continue your activity
Correct Answer: C
Rationale: During a thunder and lightning storm, the safest course of action is to get into a metal car or lie flat on the ground. Standing under a tree is dangerous as trees can attract lightning. Seeking shelter in a wooden building is also risky as wood is a conductor of electricity. Staying outside and continuing activities during a lightning storm is extremely dangerous and should be avoided at all costs. The metal car or lying flat on the ground provide a path of low resistance for the lightning, reducing the risk of harm.
The federal government regulates dietary supplements through the United States Food and Drug Administration (FDA). The regulations for dietary supplements are not the same as those for prescription or over-the-counter drugs. In general, the regulations for dietary supplements are less strict. To begin with, a manufacturer does not have to prove the safety and effectiveness of a dietary supplement before it is marketed. A manufacturer is permitted to say that a dietary supplement addresses a nutrient deficiency, supports health, or is linked to a particular body function (such as immunity) if there is research to support the claim. Such a claim must be followed by the words, “This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.†Also, manufacturers are expected to follow certain good manufacturing practices (GMPs) to ensure that dietary supplements are processed consistently and meet quality standards. Requirements for GMPs went into effect in 2008 for large manufacturers and are being phased in for small manufacturers through 2010. Once a dietary supplement is on the market, the FDA monitors safety and product information, such as label claims and package inserts. If it finds a product to be unsafe, it can take action against the manufacturer and/or distributor and may issue a warning or require that the product be removed from the marketplace. The Federal Trade Commission (FTC) is responsible for regulating product advertising; it requires that all information be truthful and not misleading. The federal government has taken legal action against a number of dietary supplement promoters or websites that promote or sell dietary supplements because they have made false or deceptive statements about their products or because marketed products have proven to be unsafe.
What is the meaning of the phrase 'phased in' as it is used in the third paragraph?
- A. stunned into silence
- B. confused
- C. implemented in stages
- D. legalized
Correct Answer: C
Rationale: The phrase 'phased in' refers to implementing something gradually or in stages. In the context provided, it means that the requirements for GMPs were gradually introduced for small manufacturers over a period of time. This approach allows for a structured implementation of the regulations, ensuring that small manufacturers have time to comply with the new standards.

The passage suggests lightning rods are used to
- A. protect people on the ground.
- B. draw lightning away from buildings.
- C. stop lightning from starting a fire.
- D. lessen the blink of lightning.
Correct Answer: C
Rationale: The correct answer is C: stop lightning from starting a fire.
Rationale:
1. The passage states that lightning rods protect buildings by forming a low resistance path for lightning, preventing it from entering the building.
2. By providing a path for lightning to follow, lightning rods reduce the risk of lightning striking a building and starting a fire.
3. Lightning rods do not protect people on the ground (choice A), draw lightning away from buildings (choice B), or lessen the blink of lightning (choice D) as their primary purpose is to provide a safe path for lightning to disperse without causing damage.
One of the best ways to understand a group of people is to know what makes them laugh. Laughter encompasses the limits of the soul and serves social, psychological, and physiological functions. In humor, life is redefined and accepted. Irony and satire provide much keener insights into a group's collective psyche and values than do years of research. It has always been a great disappointment to Native Americans that the humorous side of their life has not been mentioned by experts on native American affairs. Rather, the image of the stern-faced redskin has been presented by the American Westerns.
What is implied by this paragraph?
- A. Native Americans really are as stern and serious as the white men make them out to be.
- B. Humor is the same all over the world.
- C. Native American humor deserves more attention.
- D. The subject has a fear of heights.
Correct Answer: C
Rationale: The paragraph emphasizes the importance of understanding a group of people through their humor, highlighting the significance of humor in defining and accepting life. It specifically mentions the lack of attention given to Native American humor, suggesting that it deserves more recognition. Therefore, the correct implication from the paragraph is that Native American humor deserves more attention, making choice C the most appropriate.
Photosynthesis is a process used by plants, algae, and certain bacteria to convert light energy into chemical energy stored in sugar molecules. This process is fundamental to life on Earth as it provides the primary source of energy for nearly all organisms. The energy is captured from sunlight by a pigment in the plants called chlorophyll, which gives plants their green color.
During photosynthesis, carbon dioxide from the air and water from the soil react in the presence of light to form sugars and oxygen. The oxygen is released into the atmosphere, which is crucial for the survival of most life forms on Earth. The sugars produced are used by the plant for energy and growth, storing excess energy as starch.
The process occurs in two main stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy in the form of ATP and NADPH. The Calvin cycle uses the ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose.
Photosynthesis not only sustains plant life but also maintains the atmospheric oxygen levels and is a key factor in the carbon cycle, helping to regulate Earth's climate.
How does photosynthesis contribute to the carbon cycle?
- A. By converting atmospheric carbon dioxide into sugars
- B. By increasing carbon dioxide absorption by animals
- C. By producing carbon monoxide
- D. By releasing carbon dioxide into the atmosphere
Correct Answer: A
Rationale: Photosynthesis contributes to the carbon cycle by converting atmospheric carbon dioxide into sugars. During photosynthesis, plants use carbon dioxide from the air and water from the soil to produce sugars. This process helps in removing carbon dioxide from the atmosphere, reducing its levels. The sugars produced are utilized by the plant for energy and growth, with excess energy stored as starch. Ultimately, this conversion of carbon dioxide into sugars is a crucial step in the carbon cycle, as it plays a significant role in regulating the levels of carbon dioxide in the atmosphere and maintaining the balance of gases essential for life on Earth.
