If, in a tennis tournament, a match reaches a fifth-set tiebreak, the lower-ranked player always loses the tiebreak
(and, therefore, the match). If Rafael, the second-ranked player, wins a tournament by beating Roger, the topranked
player, then the match must not have included a fifth-set tiebreak. Which of the following arguments most
closely mimics the reasoning used in the above argument?
I have a set of some really challenging CR questions. If anyone requires it, please ping me with your email id.
United Energy recently invested in a series of large windmills which are able to produce renewable energy with minimal negative effect to the environment. The company has not drilled oil wells in the same area, even though greater revenues and profits could be generated from oil wells. Because any drilling would disrupt the native habitat of certain marine species in the area, some environmentalists assert that, by foregoing this drilling, United Energy has established that it places environmental impact over financial returns. However, United Energy may be acting in a manner consistent with its financial goals. Recent patterns of increasing annual hurricane activity have some experts questioning the long-term viability and profitability of oil wells in the area. The two boldfaced portions play which of the following roles?
In the past 50 years, the population of honeybees in the United States has been cut in half. The decline is due primarily to the increasing use of pesticides in the United States, as well as to the introduction of two types of mites that weaken and kill the bees. Honeybees are the primary pollinators for a variety of important fruit crops, including oranges, apples, grapes, peaches, cranberries and watermelons. Therefore, if the honey bee population continues this drastic decline, then most fruits will no longer be available to consumers.
In evaluating the conclusion, which of the following questions would be LEAST useful to answer?
A Are there other insect pollinators that could pollinate these fruit crops instead of the honeybee?
B Are honeybee populations declining in other important fruit-producing regions, like Chile and New Zealand?
C Is it feasible for humans to hand-pollinate the fruits that have been pollinated by bees?
D Will reducing the use of pesticides in the United States reverse the decline in honeybee populations?
E Is it possible to genetically engineer fruit-producing plants so that they no longer require pollination?
explain your answer too.
Drinking Roost, a children's health drink, must be a good habit. This substantially increases the stamina and IQ required by children for winning competitive cricket matches. Interviews conducted with young cricketers who drank one cup of Roost each before and after the match, confirmed that the players were feeling much fresher than those who did not take the health drink
What is the principal flaw in the above reasoning?
Most cable television companies currently require customers to subscribe
to packages of channels, but consumer groups have recently proposed
legislation that would force the companies to offer a la carte pricing.
Subscribers would pay less, argue the consumer groups, because they
could purchase only the desired channels. However, the cable industry
argues that under the current package pricing, popular channels
subsidize less-popular ones, providing more options for viewers. For
this reason, the industry claims that it is always cheaper for the
consumer to purchase many bundled channels than to buy them
individually. Which of the following would be most important for the
government to determine before deciding whether to require cable
television companies to offer a la carte pricing in order to reduce
Numismatist: In medieval Spain, most gold coins were minted from gold mined in West Africa, in the area that is now Senegal. The gold mined in this region was the purest known. Its gold content of 92 percent allowed coins to be minted without refining the gold, and indeed coins minted from this source of gold can be recognized because they have that gold content. The mints could refine gold and produced other kinds of coins that had much purer gold content, but the Senegalese gold was never refined.
Which one of the following inferences about gold coins minted in medieval Spain is most strongly supported by the information the numismatist gives? i
Conservation Plan (HCP) is based on a law that allows developers to use land
inhabited by endangered species in exchange for a promise to preserve critical
habitat or provide replacement land nearby. Some individuals of endangered
species are lost in return for assurances by the owner or developer that
habitat for those remaining animals will be protected. Environmentalists are
pleased that HCPs allowed them to win concessions from developers who would
otherwise ignore rarely enforced environmental laws. Satisfied property owners
prefer HCPs to more restrictive prohibitions of land use.
The situation described above most closely conforms to which one of the following principles?
Along with type of historians, with their varying bias, have gone changes in the attitude to the content of Indian history. Here Indian historians have been influenced both by their local situation and by changes of thought elsewhere. It is in this field that this work can claim some attention since it seeks to break new ground, or perhaps to deepen a freshly turned furrow in the field of Indian history. The early official historians were content with the glamour and drama of political history: Plassey to the Mutiny, from Dupleix to the Sikhs. But when the raj was settled down, glamour departed from politics, and they turned to the less glorious but more solid ground of administration. Not how India was conquered but how it was governed was the theme of this school of historians. It found its archpriest in H.H. Dodwell, its priestess in Dame Lilian Penson, and its chief shrine in the Volume VI of the Cambridge History of India. Meanwhile in Britain other currents were moving which led historical study into the economic and social fields. R.C Dutt entered the first of these currents with Economic History of India to be followed more recently by the whole group of Indian economic historians. W.E. Moreland extended these studies to the Mughal Period. Social history is now being increasingly studied and there is also of course a school of nationalist historians who see modern Indian history in terms of the rise and the fulfillment of the national movement.
According to the outlines which of the following is not among the attitude of Indian historian of Indian origin?
