Name: Analytical Reasoning - ii

Description:

To answer any question choose the answer you think is most appropriate among the given options.

Questions 1 - 3

In an experiment conducted at a laboratory, 160 white mice were injected with Serum D. 160 other white mice were injected with a harmless sugar solution .In two weeks time 39% of the white mice, who were injected with Serum D contracted the highly contagious and often fatal disease, jungle fever. Hence, it can be concluded that jungle fever is caused by some elements similar to the elements in Serum D.

The above discussion would be weakened most severely in case it is shown that
1. People contracting jungle fever are usually the victims of the bite of the South American Lesser Hooded Viper.
2. One among the 160 white mice had already contracted jungle fever prior to the laboratory experiment.
3. The natural habitats of white mice does not contain any of the elements found in Serum D.
4. The scientists administered the injections being ignorant of the contents of the solutions used.
5. The 160 white mice used in the laboratory experiment were kept isolated from each other.
Ans : B
The above argument would be highly empowered in case it were shown that:
1. Some of the elements in Serum D are extracted from the root of a certain poisonous jungle wildflower.
2. Within a period of two weeks about 40% of the white mice, who were injected with a harmless sugar solution also contracted jungle fever.
3. Almost all the white mice died within a period of two days after the first symptoms appeared.
4. Normally the rate of jungle fever among white mice is less than 0.01%.
5. Invariably the blood of the victims of jungle fever victims contains a high level of a certain toxic substance also found in serum D.
Ans : E

2. Radicals and fanatics prefer the use of public property while propagating their viewpoint.
3. Every person who hands out leaflets and delivers speeches is a radical or fanatic.
4. Legal constraints which are applicable to one group need not be equally applicable to all.
5. Any political activity, which hinders the proper functioning of the government should not be protected by the law.
