None Q. 2 A study at Institute of Public Health has shown that there are still millions of people who are unaware that they endanger their health by over eating. This is so, despite government campaigns to warn people of the dangers of over eating. Reluctantly, one has to draw the conclusion that the mandatory warnings that nutrition companies are required to print have had no effect. Which of the following, if true, would refute the argument in the passage?Deselect Answer Many people who continue to eat more are aware of the dangers of over eating. Some people eat more food for legitimate reasons. Government has had to force companies to warn potential customers of the dangers of over use of their products. Some people who are aware of the dangers of over eating were made aware of them by the mandatory warnings. Over eating is clearly responsible for a substantial proportion of preventable illness in the country. None Q. 3 There are plenty of debates on whether a college education is worth it or not. People who argue that college is worth it contend that college graduates have higher employment rates, bigger salaries, and more work benefits than high school graduates. They say college graduates also have better interpersonal skills, live longer, have healthier children, and have proven their ability to achieve a major milestone.Which of the following statements, if true, most strongly supports the view that college education is worth it?Deselect Answer Student loan debt is crippling for college graduates. Many successful people never graduated from college and that many jobs, especially trades jobs, do not require college degrees. According to the Bureau of Labor Statistics, of the 30 projected fastest growing jobs between 2010 and 2020, five do not require a high school diploma, nine require a high school diploma, four require an associate's degree, six require a bachelor's degree, and six require graduate degrees The 2017 poverty rate for bachelor's degree holders was 4%, compared to a 12% poverty rate for high school graduates. Some students who has collage degree gets high-paid jobs. None Q. 4 India’s baffling array of state and national labor laws date to the 1940s: one provides for the type and number of spittoons in a factory. Another says an enterprise with more than 100 workers needs government permission to scale back or close. Many Indian businesses stay small in order to remain beyond the reach of the laws. Big firms use temporary workers to avoid them. Less than 15% of Indian workers have legal job security. The new government can sidestep the difficult politics of curbing privileges by establishing a new, simpler labor contract that gives basic protection to workers but makes lay-offs less costly to firms. It would apply only to new hires; the small proportion of existing workers with gold-star protections would keep them.Which of the following options best summarizes the main idea of the paragraph?Deselect Answer More Indian workers can get permanent jobs and legal job security if existing labor laws are reformed. Effective labor law reform can encourage many Indian businesses to grow to more than 100 workers. Outdated Indian labor laws need to be simplified to provide basic protection to workers and curb privileges. The difficult politics of curbing privileges can be avoided if the changes in the labor law only apply to the new hires. Some firms uses low-paid workers to avoid the laws None Q. 5 Jason: The Internet is making more information available to more people than ever before in history. So, people can simply learn all they need to know without seeking the advice of experts. Mark: In the past, the need for experts actually increased as the volume of knowledge increased.

This paragraph best supports the statement thatDeselect Answer toxic insecticides such as DDT have not been banned throughout the world. more pollutants find their way into polar climates than they do into warmer areas. studies have proven that many countries have ignored their own anti-pollution laws DDT and toxaphene are the two most toxic insecticides in the world. even a worldwide ban on toxic insecticides would not stop the spread of DDT pollution. None Q. 8 Today’s postal service is more efficient than ever. Mail that once took months to move by horse and foot now moves around the country in days or hours by truck, train, and plane. If your letter or package is urgent, the U.S. Postal Service offers Priority Mail and Express Mail services. Priority Mail is guaranteed to go anywhere in the United States in two days or less. Express Mail will get your package there overnight. This paragraph best supports the statement thatDeselect Answer more people use the post office for urgent deliveries than any other delivery service. Express Mail is a good way to send urgent mail.

In response to ADH, the collecting duct and distal tubule in the kidney become more permeable to water, which increases water reabsorption into the capillaries. The amount of hormone released is controlled by a negative feedback loop. Based on the model presented, which of the following statements expresses the proper relationship between osmolarity, ADH release, and urine production?Deselect Answer As tissue osmolarity rises, more ADH is released, causing less water to be excreted as urine. As tissue osmolarity rises, less ADH is released, causing less water to be excreted as urine. As tissue osmolarity rises, more ADH is released, causing more water to be excreted as urine. As tissue osmolarity rises, less ADH is released, causing more water to be excreted as urine. As tissue osmolarity reduces more ADH is released, causing less water to be excreted as urine None Q. 30 Platelets are fragments oflarger celis and normaliy circulate in the blood without adhering to blood vessel walls. When the wall ofa blood vessel is damaged, collagen fibers in the wall are exposed to the interior of the blood vessel. The exposed fibers and chemicals released from the endothelial celis that line the blood vessel attract platelets, which start to form a Plug and release other chemicals (Figure I).Which of the following best explains the feedback mechanism illustrated in Figure I ?Deselect Answer This is an example of positive feedback, because the few platelets that initially bind attract more platelets to the damaged area. This is an example of positive feedback, because it results from the interactions among collagen, endothelial cells, and platelets. This is an example of negative feedback, because a large clump of platelets can block the blood vessel and prevent blood flow through it. This is an example of negative feedback, because the accumulation of platelets returns the open blood vessel wall to a closed state. This is an example of negative feedback because vessel wall returns to its first State None Q. 31 Which option correctly identifies the site of the light-dependent reactions in photosynthesis (S), the hydrogen carrier (H) used and its end state (N)?Deselect Answer S: stroma; H: FAD; N: oxidized S: stroma; H: NAD; N: reduced S: stroma; H: NADP; N: oxidized S: granum; H: NAD; N: reduced S: granum; H: NADP; N: reduced None Q. 32 The apple maggot fly, Rhagoletis pomonella, is native to North America and originally fed on fruit of the Wild hawthorn.

Many varieties of apples ripen three to four weeks before the hawthorn fruits do.The different fruit preferences of the two fly populations Will most likely have which of the following effects?Deselect Answer The flies that eat hawthorn fruit Will increase in number, while the flies that eat apples Will decrease in number because of the üşe of insecticides on apple trees. The single fly species Will evolve into two distinct species because of the lack of gene flow between the two populations. The ability to survive on a diet oftwo different fruits Will help the flies learn to eat many more types offruit.
