Passage
Turf grasses are used throughout the United States in many suburban lawns. Kentucky bluegrass is the most common type of turf grass used in the northern part of the United States. To keep lawns green and healthy, many homeowners apply fertilizer up to ﬁve times a year. Inorganic fertilizers are becoming more popular, and contain three common elements – nitrogen, phosphorous, and potassium – for the development of plant color, strength, and health. Most turf grass lawns do not use all of the nutrients provided in the fertilizer, which means that much of the nitrogen, phosphorous, and potassium remains in the soil. When water enters the soil, it accumulates a portion of the excess nitrogen from the soil. This water, now termed leachate, ﬂows into surrounding waterways. The leaching of high concentrations of nitrogen into natural waterways can throw off the environmental equilibrium of the aquatic ecosystem, often resulting in an increase in plant growth that can have a negative impact on the native ﬁsh populations.
A study was performed to examine the degree of nitrogen leaching in Kentucky bluegrass turf; 2 one-acre plots of turf were compared. The scientists conducting the study relied completely on natural rainwater to irrigate the test plots. Each plot received fertilizer applications containing different levels of nitrogen two times per week during the months of April and September for 5 years. The plots had a 5% slope to facilitate leaching; leachate was collected in one-liter jugs. The leachate collected from each plot was measured for nitrogen concentration.
Plot A, received a low nitrogen application, 98 kilograms of N per acre from 2000 to 2004. Plot B, received an initially high nitrogen application, 245 kilograms of N per acre from 2000–2002. In the last year of the study, the amount of nitrogen in the fertilizer was decreased to 196 kilograms of N per acre for Plot B. Table 1 shows the average nitrogen concentration in milligrams per liter (mg/L) in the leachate collected from each plot during each year. Figure 1 shows the percent concentration of nitrogen in the leachate.

Q. In 2005, it was found that average nitrogen levels in the leachate from Plot B were 8.2 mg/L. The data from the study supports which of the following conclusions?

a)
Kentucky bluegrass should not be used for lawns in suburbs near a public waterway.
b)
Once high-nitrogen fertilizer has been applied to a suburban lawn, nitrogen levels in the leachate will remain high, even if low-nitrogen fertilizer is later applied.
c)
Following the application of low-nitrogen fertilizers, it will take more than one year to reach safe nitrogen levels in leachate from suburban lawns previously fertilized with high-nitrogen fertilizer.
d)
The measurable concentration of nitrogen in leachate from suburban lawns will always be within the range considered safe by the Environmental Protection Agency, as long as irrigation is kept to a minimum.

Correct answer is option 'D'. Can you explain this answer?

According to the passage, the nitrogen levels in the fertilizer applied to Plot B were reduced in 2004. However, Table 1 shows that the nitrogen concentration in the leachate from Plot B was 11.8 mg/L, which is still considered unsafe. In 2005, the concentration had gone down to a safe 8.2 mg/L. Therefore, you can conclude that it will take more than one year to reach safe nitrogen levels in the leachate. The other answer choices are not supported by the data.

Directions: Read the passages and choose the best answer to each question.PassageA number of different chemical elements are essential for the survival and growth of plants. The macronutrients— those nutrients required in the greatest quantity—are nitrogen, phosphorus, and potassium. These macronutrients are only available in the soil and generally come from the decay of other plants. To enrich the soil and make more of these essential nutrients available, many people use fertilizers to supply plants with the nutrients they need to grow faster. Two botanists discuss whether inorganic or organic fertilizers are most optimal for plant growth.Botanist 1In addition to carbon, hydrogen, and oxygen available in the water and the air, and other micronutrients, such as sulfur, calcium, and magnesium, plants also need the macronutrients nitrogen, phosphorus, and potassium to thrive. The best way to supply the soil, and thus the plants, with the proper macronutrients is to apply organic fertilizers, as opposed to commercial inorganic fertilizers. Organic nutrients include cow, poultry, horse, and sheep manures.Green manure—a crop that is grown for a speciﬁc period of time, then plowed and incorporated into the soil—and compost can also be used. Organic fertilization mimics the natural breakdown of organic material into nutrients for which the plants can use. In other words, organic fertilizer provides a naturally slow release of nutrients as the organic material breaks down in the soil, reducing the likelihood of over-fertilization. Organic fertilizers also improve soil structure in the long term and improve the ability of sandy soils to hold water, which is immensely important in arid climates. Commercial inorganic fertilizers, on the other hand, are often applied too heavily, damaging the roots of the plants. Inorganic fertilizers can also cause chemical imbalances in the soil because they can build up a toxic concentration of salts in the soil.Botanist 2Plant growth and survival depends on an adequate supply of essential nutrients that cannot always be found in the soil. Inorganic commercial fertilizers have many beneﬁts over organic fertilizers. The elements in inorganic fertilizers have been thoroughly measured and tested, insuring that each application provides the appropriate amount ofnutrients to the plants, as opposed to the highly variable, and often unknown, nutrient content of organic fertilizers.Organic fertilizers are usually lower in nutrient content than inorganic fertilizers, requiring more of the organic material to be applied to achieve the same level of nutrient delivery acquired from the application of smaller amounts of inorganic material. In addition, characteristics of organic fertilizer require application well in advance of need to ensure that the materials have broken down and can be used by the plant. Inorganic fertilizers, however, once applied, offer immediate availability of nutrients to plants for use.The likelihood of nitrogen depletion is another disadvantage of organic fertilizers. Organic material can cause a temporary depletion of nitrogen in the soil and therefore in the plants that depend on it. Inorganic fertilizer use does not present this problem.Q.Which of the following best describes the difference between the two botanists’ opinions?

Plot B, received an initially high nitrogen application, 245 kilograms of N per acre from 2000–2002. In the last year of the study, the amount of nitrogen in the fertilizer was decreased to 196 kilograms of N per acre for Plot B. Table 1 shows the average nitrogen concentration in milligrams per liter (mg/L) in the leachate collected from each plot during each year. Figure 1 shows the percent concentration of nitrogen in the leachate.Q.In 2005, it was found that average nitrogen levels in the leachate from Plot B were 8.2 mg/L. The data from the study supports which of the following conclusions?a)Kentucky bluegrass should not be used for lawns in suburbs near a public waterway.b)Once high-nitrogen fertilizer has been applied to a suburban lawn, nitrogen levels in the leachate will remain high, even if low-nitrogen fertilizer is later applied.c)Following the application of low-nitrogen fertilizers, it will take more than one year to reach safe nitrogen levels in leachate from suburban lawns previously fertilized with high-nitrogen fertilizer.d)The measurable concentration of nitrogen in leachate from suburban lawns will always be within the range considered safe by the Environmental Protection Agency, as long as irrigation is kept to a minimum.Correct answer is option 'D'.

Kentucky bluegrass is the most common type of turf grass used in the northern part of the United States. To keep lawns green and healthy, many homeowners apply fertilizer up to ﬁve times a year. Inorganic fertilizers are becoming more popular, and contain three common elements – nitrogen, phosphorous, and potassium – for the development of plant color, strength, and health. Most turf grass lawns do not use all of the nutrients provided in the fertilizer, which means that much of the nitrogen, phosphorous, and potassium remains in the soil. When water enters the soil, it accumulates a portion of the excess nitrogen from the soil. This water, now termed leachate, ﬂows into surrounding waterways. The leaching of high concentrations of nitrogen into natural waterways can throw off the environmental equilibrium of the aquatic ecosystem, often resulting in an increase in plant growth that can have a negative impact on the native ﬁsh populations.A study was performed to examine the degree of nitrogen leaching in Kentucky bluegrass turf; 2 one-acre plots of turf were compared. The scientists conducting the study relied completely on natural rainwater to irrigate the test plots. Each plot received fertilizer applications containing different levels of nitrogen two times per week during the months of April and September for 5 years. The plots had a 5% slope to facilitate leaching; leachate was collected in one-liter jugs. The leachate collected from each plot was measured for nitrogen concentration.Plot A, received a low nitrogen application, 98 kilograms of N per acre from 2000 to 2004.
