Food Crops 5 Bonus Structure— As a result means “therefore,” “for this reason.” Several agencies and organizations have intensified their efforts to increase the productivity of land in these countries.They have introduced new strains of seed, improved irrigation techniques, and introduced new methods of fertilization and soil management.With ample sunlight for photosynthesis and modern irrigation techniques, sustainable farming techniques should allow farmers to boost aggregate production in order to meet demand. Still, crop revitalization faces an unexpected adversary: institutional incompetence.Where crop specialists have convinced individual farmers to abandon old farming techniques in place of new, they can’t readily obtain the governmental cooperation they need.The biggest hurdles are political corruption, incompetence, and the absence of a marketing infrastructure. 1.

Answer the questions that follow. Nature challenges humans in many ways, through disease, weather, and famine. For those living along the coast, one unusual phenomenon capable of catastrophic destruction is the tsunami (pronounced “tsoo-NAH-mee”). A tsunami is a series of waves generated in a body of water by an impulsive disturbance. Earthquakes, landslides, volcanic eruptions, explosions, and even the impact of meteorites can generate tsunamis. Starting at sea, a tsunami slowly approaches land, growing in height and losing energy through bottom friction and turbulence. Still, just like any other water waves, tsunamis unleash tremendous energy as they plunge onto the shore.They have great erosion potential, stripping beaches of sand, undermining trees, and flooding hundreds of meters inland.They can easily crush cars, homes, vegetation, and anything they collide with. To minimize the devastation of a tsunami, scientists are constantly trying to anticipate them more accurately and more quickly. Because many factors come together to produce a life-threatening tsunami, foreseeing them is not easy. Despite this, researchers in meteorology persevere in studying and predicting tsunami behavior. 1. Which sentence best expresses the essential information of this passage? a. Tsunamis could become a new source of usable energy in the next hundred years. b. Tsunamis do more damage to the land than flooding. c. Tsunamis can have an especially catastrophic impact on coastal communities. d. Scientists can predict and track tsunamis with a fair degree of accuracy, reducing their potential impact. 2.

TOEFL Success Read the passage to review the vocabulary you have learned. Answer the questions that follow. The migration from Asia to North America across the Bering Strait (perhaps by land bridge) was a monumental event in human history.The process of overspreading the Americas took more than 1,000 years, or 30 generations.This might seem to confirm common sense—that slow travel was inherent in any great migration without wheeled vehicles across unknown terrain. Further thought shows that this process was remarkably fast—about 10 northsouth miles per year, on average. The Americas were populated at an astounding pace, when one considers the physical limits of the human body and the physical features of the American continents. Legs of humans can move only so fast under the best of circumstances, and they work even slower over mountain passes or deserts. Populations spread through the diverse regions of the Americas (grasslands, eastern forests, coastal swamps) and needed to adapt to their new environments.The migrants’ lifestyle had evolved over the years to that of professional nomads ensuring that they would find the resources needed to survive.

Human consumption of fossil fuels is expected to fully deplete the Earth’s crude oil reserves by the year 2060.As underground reservoirs of oil continue to shrink, we have no choice but to find alternatives. One promising source, with much cleaner emissions, is called bio-diesel. Bio- Petroleum Alternatives 19 Bonus Structure— One promising source signals the point of this paragraph. diesel is often made from soybean oil, although it can be made from any vegetable oil that is not elementally different from soy. Bio-diesel can even be made from used cooking oils that homes or restaurants would otherwise dispose of. Bio-diesel can be used without constraint in any vehicle that runs on diesel—no modifications are needed. Presently, diesel engines can take up to 20 percent soy in their soy-diesel blend.As the need for bio-diesel increases and the technology improves,we may soon witness the extinction of the fossil-fueled vehicle.This is good news for the planet, as bio-diesel is a more stable source of energy than petroleum, and it reduces contamination of our air and water. An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the three answer choices that express the most important ideas in the passage. In each blank, write the letter of one of your choices. a. Humans have shown little self-restraint in their consumption of fossil fuels. b. Underground reservoirs of oil will soon be depleted. c.
