Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.Living things include both the visible world of animals, plants, and fungi as well as the invisible world of bacteria and viruses. On a basic level, we can say that life is ordered. Organizations have an enormously complex organization. We’re all familiar with the intricate systems of the basic unit of life, the cell. Life can also “work.” Living creatures can take in energy from the environment. This energy, in the form of food, is transformed to maintain metabolic processes and for survival. Life grows and develops. This means more than just replicating or getting larger in size. Living organisms also have the ability to rebuild and repair themselves when injured. Life can reproduce. Think about the last time you accidentally stubbed your toe. Almost instantly, you moved back in pain. Finally, life can adapt and respond to the demands placed on it by the environment. There are three basic types of adaptations that can occur in higher organisms. Reversible changes occur as a response to changes in the environment. Let’s say you live near sea level and you travel to an approximate area. You may begin to experience difficulty breathing and an increase in heart rate as a result of the change in altitude. These symptoms go away when you go back down to sea level. Body-related changes occur as a result of prolonged changes in the environment. Using there previous example if you were to stay in the heart normally, you would notice that your heart normally and would begin to slow down normally and would begin to breath normally. These changes are also reversible. Genotypic changes (caused by genetic mutation) take place within the genetic makeup of the organism and are not reversible. An example would be the development of resistance to pesticides by insects and spiders. Which type of living creatures can adapt to the changes in the environment?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. Given the American manufacturing tradition, it was also inevitable that cars would be produced in larger volume at lower prices than in Europe. The absence of tariff barriers between the states encourages sales over a wide geographic area. Cheap raw materials and a chronic shortage of skilled labor soon encouraged the mechanization of industrial processes in the United States. This in turn requires the standardization of products and results in the volume production of such commodities as firearms, sewing machines, bicycles, and many other items. In 1913, the United States produced some 485,000 of the world total of 606,124 motor vehicles. The Ford Motor Company greatly outpaced its competitors in reconciling state-of-the-art design with moderate price. Cycle and Automobile Trade Journal called the four-cylinder, fifteen-horsepower, $600 Ford Model N (1906-1907) “the very first instance of a low-cost motor car driven by a gas engine having cylinders enough to give the shaft a turning impulse in each shaft turn which is well built and offered in large numbers.” Deluged with orders, Ford installed improved production equipment and after 1906 was able to make deliveries of a hundred cars a day. Encouraged by the success of the Model N, Henry Ford was determined to build an even better “car for the great multitude.” The four-cylinder, twenty-horsepower Model T, first offered in October 1908, sold for $825. Its two-speed planetary transmission made it easy to drive, and features such as its detachable cylinder head made it easy to repair. Its high chassis was designed to clear the bumps in rural roads. Vanadium steel makes the Model T a lighter and tougher car, and new methods of casting parts (especially block casting of the engine) helped keep the price down. Committed to large-volume production of the Model T, Ford innovated modern mass production techniques at his new Highland Park, Michigan, plant, which opened in 1910 (although he did not introduce the moving assembly line until 1913-1914). The Model T runabout sold for $575 in 1912, less than the average annual wage in the United States. By the time the Model T was withdrawn from production in 1927, its price had been reduced to $290 for the coupe, 15 million units had been sold, and mass personal “automobility” had become a reality. Which best serves as the title for the passage?
