Question 393. Most scientists now believe that the near extinction of the cobra in the North Indian forests was due to the extensive hunting down of the poor creature by the tribals of the forest. During the 40s and the 50s cobra was in great demand for its medicinal use which the tribals exploited greatly, the scientists say.Which of the following, weakens the above argument?

None of these

Discuss Question

Answer: Option C. -> The extensive government sponsored logging operations of the 40s and the 50s in the North Indian forests led to the immediate extinction of rodents, a major prey of snakes.

The correct answer is c. To weaken an argument, we should show the assumption in the argument to be false. The assumption in the given argument is that there is no other cause for the near extinction of the cobra. If we prove this wrong, it weakens the argument. Choice (c), by showing an alternative cause, does this. Others are either irrelevant or out of scope.

Question 394. Despite inflation which has resulted in increased prices of raw materials, a city book manufacturer decided not to increase the price of his books. Instead he decided to use low-priced inferior material. This, he feels will not result in any change in business and continue to give him the same profits as earlier.

The fashion of reading books is fast catching up with the people in urban society and they are unmindful of the price.
Most readers are unmindful of the quality of books so far as the print is legible.
The WTO predicated that inflation in cities would come down in the coming days.
None of these.

Discuss Question

Answer: Option C. -> Most readers are unmindful of the quality of books so far as the print is legible.

The correct answer is (c). The manufacturer decides to use cheaper material without changing the cost of his books and hopes for the the same profit. His assumption is , people will not mind the cheaper quality. The cheaper material shall result in the same is shown to be true in (c). [To. strengthen an argument, we should show the assumption to be true]. The other choices are irrelevant or out of scope.

Question 395. Nokia India has two manufacturing units one each in China and Japan. It recently discovered that each mobile manufactured in Japan yield less profit than similar one in China. This is because the tariff on mobiles imported from China to India is 10% less than that when imported from Japan and both are priced equally.
Which of the following if true, supports the conclusion in the given argument?

The cost of manufacturing mobiles in Japan is 8% more than that in China.
The labour cost in China is 12% more than in Japan.
China and India have a mutually supportive cultural relationship.
Japan has had an undue competitive edge over China.
None of these

Discuss Question

Answer: Option A. -> The cost of manufacturing mobiles in Japan is 8% more than that in China.

The correct answer is (a). The argument assumes that there is no other difference which may neutralize or negate the 10% tariff difference in favour of China. If we show this to be true (or if we show yet another difference in favour of China), we strengthen the argument. This is exactly what choice (a) does. Choice (b) weakens the argument. Choice (c) and (d) are irrelevant.

Question 396. It has been seen that whenever a certain movie in Bollywood is a major success, the subsequent movies follow suit, literally. Almost all the movies made after that are of the same type. Obviously, the 'formula' which the public is known to have loved and approved is simply repeated by the people in the industry for sure success.Which of the following, if true, weakens the above argument?

The producers and directors in Bollywood actually keep in mind the public mood while making movies.
A movie's success does not depend upon various parameters like who the hero or heroine is, whose music it has, who's directing or producing it etc.
Many movies that copied the formula of a successful movie went on to become, some of the great flops.
Almost all the Bollywood authors are uninnovative and have run out of ideas and so tend to simply 'redesign' a recent hit.
None of these

Discuss Question

Answer: Option D. -> Almost all the Bollywood authors are uninnovative and have run out of ideas and so tend to simply 'redesign' a recent hit.

The correct answer is (d). The conclusion of the argument is that because the public loved and approved a certain formula, Bollywood repeats it for sure success.The assumption is there is no other cause / reason. If we show one, we weaken it. Choice (d) gives us an alternative cause: the not so creative writers don't have any ideas at all. If they had, they would write new stories. Choice (a) strengthens the argument by asserting the same conclusion. Choices (b) and (c) are irrelevant.

Question 397. The quantity of junk food sold in Rampur is far greater than that sold in Jaipur. It follows that the people of Jaipur have better nutritional habit than those of Rampur. Scientists claim that most people eat junk food these days which is not good for health.Which of the following, if true, weakens the above argument?

Most people from Rampur work at Jaipur and buy food items at Jaipur which they leave at home.
The population of Jaipur is not less than Rampur's.
Lakhs of devotees from cities visit Rampur's ancient temple of Lord Rama on weekends.
A recent survey found that on an average a person from Rampur eats four times the quantity of chat a person from Jaipur eats.
None of these.

Discuss Question

Answer: Option C. -> Lakhs of devotees from cities visit Rampur's ancient temple of Lord Rama on weekends.

The correct answer is choice (c). The assumption is that their is no other explanation for the 'increased' quantity of junk food sold in Rampur. However, choice (c) gives us one. If the scientists are true, then some of these 'lakhs' of devotees must be buying junk food in Rampur on their visit and this may be the actual reason for the increase in junk food consumption. Choice (a) strengthens the argument. Choice (b) and (d) are irrelevant.

Question 398. Statement:Children catch infections when they eat roadside food.Courses of Action:I. Parents should not allow their children to eat roadside food but rather try to prepare that type of food at home.II. The children should be taught about what is healthy food and that the type of food prepared on the road side is not healthy.

Discuss Question

Answer: Option C. -> if either I or II follows.

These statement does not indicate why the roadside food leads to infection. It may be because it is cooked in unhygienic conditions. In such a case, I is a proper course of action but not II. If the food itself is unhealthy, then II is a proper course of action but not I. Hence, either I or II follows.

Question 399. Statement:Pedestrians find it very difficult to cross the road at the peak hours.Courses of Action:I. The Traffic Control Authority should provide more number of traffic signals and zebra crossings, which enable the pedestrians to cross the road easily.II. The authority should build more number of skywalks across the busy roads, which will provide easy crossing for the pedestrians without disturbing the movement of traffic.

Discuss Question

Answer: Option B. -> If only II follows.

The course of action I can solve the problem but it would affect the free flow of traffic. So, I is not a proper course of action.Course of action II provides easy crossing without disrupting the traffic. So, II is a proper course of action.
