A) we are not concerned with percentages as premise evaluates the condition based on hard numbers eg - 100 people in total in 2000 50 affected by famine, so 50% affected 200 people in total in 2010 100 affected by famine, again 50% affected surely, number of people affected increased but "percentage" remained same. B) this seems ok as we have narrowed our comparison between 2 years C) not concerned "if the population decreased" we are talking about increasing trend D) "concern" about famine is not our concern E) increased "every year" - is too much assumption on the plate option (B) seems "best" of all other choices available
Good explanation

Q1. A growing world population has caused growing concerns about increasing famine. The population in 2000 was 6 billion. Ten years later the population was 7 billion. There were also more people affected by famines in 2010 than in 2000. Furthermore, in each year from 2000 to 2010, when the world’s population increased, so did the number of those affected by famine. Based on the information given, which of the following is true? A. From 2000 to 2010, when the world’s population increased, the percentage of the population affected by famine also increased B. If the population increased in 2005, then more people were affected by famine in 2005 than in 2004 C. If the population decreased in a particular year between 2000 and 2010, the number of those affected by famine also decreased in that year D. There was greater concern about famine in 2010 than in 2000 E. The population increased in every year between 2000 to 2010

Q2. Previously, no speed limits were set on drivers in Bravia, and it was left to the discretion of the Bravian drivers to drive prudently. In 2005, in an attempt to reduce instances of speeding and thereby reduce speeding induced fatalities among the Bravian drivers, the government introduced speeding limits. Such fatalities have reduced significantly since the introduction of speeding limits. However, data from traffic cameras show that the proportion of drivers who were driving their vehicles at high speeds is not lower than that before 2005. Which of the following, if true of Bravia, most helps to resolve the apparent discrepancy? A. The proportion of cars being driven on the roads post 2005 is not the same as prior to 2005. B. The proportion of people using seat belts and air-bags, proven to be effective safety measures, has increased significantly post 2004. C. Speeding is higher among the younger set of drivers than among the older, more cautious ones. D. Most people find it very hard to give up their old habits of speeding even when faced with regulations restraining them from it. E. The number of miles driven per car on average is no lower than it was prior to 2005.
CR Questions January- 19 :Q1. Political scientist: One of the most interesting dilemmas in contemporary democratic politics concerns the regulation of political campaign spending. People certainly should be free, within broad limits, to spend their money as they choose. On the other hand, candidates who can vastly outspend all rivals have an unfair advantage in publicizing their platforms. Democratic governments have a strong obligation to ensure that all voices have an equal chance to be heard, but governments should not subsidize expensive campaigns for each candidate. The resolution of the dilemma, therefore, is clear: _______.
Which one of the following most logically completes the political scientist’s argument?
A. only candidates with significant campaign resources should be permitted to run for public office
B. an upper limit on the political campaign spending of each candidate is warranted
C. government subsidization of all political campaigns at a low percentage of their total cost is warranted
D. all wealthy persons should be prohibited from spending their own money on political campaigns
E. each candidate should be allowed to spend as much money on a political campaign as any other candidate chooses to spend
Q2. Recently, a team of scientists digging through a tar pit unearthed a jawbone fossil. Initially, the team hypothesized that the jawbone came from a young gomphothere, a now extinct distant relative of the elephant, since the teeth were those of a juvenile. The gomphothere, however, is known for its large molars, and the teeth on the jawbone would not allow enough room for the molars of an adult gomphothere to fit. Based on this evidence, the scientists conclude that the jawbone fossil provides evidence of a distinct species closely related to the gomphothere.
Which of the following, if true, would best provide evidence showing that the conclusion above is possibly flawed?
(A) The manner in which teeth grow provide sufficient evidence for the accurate classification of a bygone species.
(B) In order for the molars of an adult gomphothereto emerge, several juvenile teeth are first forced out of the gums to accommodate the molars.
(C) The molars of an adult mastodon, a close relative of the gomphothere, are similar in size to those of an adult gomphothere.
(D) Many fossils exist that have yet to be conclusively attributed to any one species.
(E) The juvenile jawbone of a species related to a gomphothere is longer than the juvenile jawbone of a gomphothere.
