Q1. Health care advocate: The advantages of eating fish are many; unfortunately fish consumption in Colton is extremely low. Splitting hairs over whether one fish has less omega-3 fatty acid per serving than other types of fish when the total fat content is low seems to miss the point. Colton’s policy-makers should encourage people to eat more fish, and then worry about fine-tuning either the fish’s diet or our diet to edge up the omega-3 content. Which of the following , if true , most seriously weakens the Health Care Advocate’s reasoning above? A. Sales of many common types of fish rich in omega-3 fatty acid have increased over recent years. B. Heavy consumption of omega-3 fatty acid frequently results in symptoms, such as headaches, and even joint pain. C. On average, people consumer 5 percent less omega-3 fatty acid today than they did 10 years ago. D. Most of Colton’s population already consume a comparable amount of food rich in omega-3 content from sources other than fish. E. Many adults currently consumer no omega-3 fatty acid from fish or from sources other than fish. Difficulty - Hard

Q2. A fossil recently discovered in Marlandia, a chain of islands, proves that a present-day reptile indigenous to Marlandia is descended from an ancient reptile species that lived on the islands millions of years ago. The finding is surprising since the ancestral species was thought to have become extinct when Marlandia was submerged in a global sea-level rise twenty-five million years ago. Based on the new discovery, many scientists have concluded that the sea-level rise in question left at least part of Marlandia unsubmerged. Which of the following would, if true, provide the most additional support for the scientists’ conclusion? A. Reptiles in Marlandia have adapted to many environmental changes since the sea-level rise. B. Marlandia separated from a much larger landmass about eighty million years ago. C. No fossils that prove the relationship between the present-day species and the ancestral species have been found anywhere other than Marlandia. D. The present-day reptiles are able to thrive on very tiny Marlandia islands. E. The ancestral reptiles could not have survived long at sea. Difficulty - Hard
CR Questions February - 19 :Q1. Scientists have modified salmon embryos genetically to increasing the embryo‖s hardiness and longevity when it grows into an adult salmon. Fish harvesters, those who grow and sell fish domestically, who tried out the genetically modified salmon embryos last year used and therefore spent less on vaccinations and medication for the fish and still got a yield (healthy fish meat that can be processed and sold as canned food) comparable to that they had got with ordinary salmon. Ordinary embryos, however, cost less, and what these fish harvesters saved on vaccines and medication was exceeded by the extra costs of the genetically engineered embryos. Therefore, for most fish harvesters, switching to genetically modified salmon embryos would be unlikely to increase profits.
The answer to which of the questions would help evaluate the conclusion that the profits are unlikely to increase.
(A) Whether there are diseases that sometimes reduce fish yield, but against which commonly used medicines, vaccination, and genetic modification are equally ineffective
(B) Whether the price that fish harvesters receive for fish yield for salmon has remained steady over the past few years
(C) Whether the vaccinations and medication typically used on fish tend to be more expensive than those typically used on other fish types
(D) Whether most of the fish harvesters who tried the genetically modified salmon embryos last year used more vaccination and medication than was actually necessary
(E) Whether it is the most profitable fish species for most fish harvesters who grow salmon

Q2. Of all the laptops available for sale in Ireland, laptops manufactured by Ivy Infotech must have the fastest processors. Over the last six months, Ivy Infotech has sold three times as many laptops as its closest competitor. Additionally, Ivy Infotech’s order books are full for the next 12 months.
Which of the following options, if true, most weakens the argument?
(A) Ivy Infotech was severely criticised last year for manufacturing laptops with slow processors.
(B) Apart from laptops, Ivy Infotech also manufactures desktops and tablets, sales of which have declined drastically in the last six months.
(C) At the same time last year, Ivy Infotech had sold 60% more laptops than it has this year.
(D) All the laptop manufacturers in Ireland, including Ivy Infotech, source their processors from the same company.
(E) Due to production bottlenecks, the production of laptops by Ivy Infotech’s rival companies fell by more than 60% in the last six months.
