Q:

In the following question, a short passage with one of the lines in the passage missing and represented by a blank is given. Select the best out of the five answer choices given, to make the passage complete and coherent (coherent means logically complete and sound).
There is a fairly universal sentiment that the use of nuclear weapons is clearly contrary to mortality and that its production probably so, does not go far enough. These activities are not only opposed to mortality but also to the law. If the legal objection can be added to the moral, the argument against the use and manufacture of these weapons will considerably be reinforced. Now the time is ripe to evaluate the responsibility of scientists who knowingly use their expertise for the construction of such weapons, which has a deleterious effect on mankind.
How appropriate it is that all this valuable skill should be devoted to the manufacture of weapons of death in a world of poverty is a question that must touch the scientific conscience.

A) Almost 50% of the skilled scientific manpower in the world is now engaged in the armaments industry. B) To think that majority of the scientists are promoting the manufacturing of the armaments is hurtful.
C) Scientists should use their conscience before taking up these contracts to manufacture the weapons of mass destruction. D) Scientific manpower is used to the interests of some selfish and careless people who want to threaten the existence of homo-sapiens.
 
Answer & Explanation Answer: A) Almost 50% of the skilled scientific manpower in the world is now engaged in the armaments industry.

Explanation:

Choice 1 is correct as it matches with the flow of the passage. The whole paragraph is about the devastating effects that nuclear weapons have due to certain curtailments on part of the
scientists in the moral and the conscience aspect. It is only logical to mention an argument to support the next statement. It also keeps up with the tone and general
subject of the passage.
Option 2 is a bad choice as it talks about absolutely nothing and is too naïve. Therefore is incorrect as it is beyond the general theme.
Option 3 is incorrect as it obviously does not go with the flow of the Para.
As for option 4, it is incorrect as the statement is illogical.
As for 5, neither does it logically follow the previous sentence nor is it related to the anything in the next sentence.
