Choice (b) may take place, because government may first safe guard the computers of other top officials from being hacked. Loss of data is not the matter here. The problem is that the data is being accessed by unauthorised persons. Hence (d) is not a possible effect. Since there is no information that hacking is done with the knowledge of the official concerned (e) is not a possible effect. Hence, (b) is a possible cause.

C. It is not desirable for the judges to pass such comments on other constitutional/ statutory bodies in their absence.

D. Freedom of expression cannot be exercised while in official capacity.

Answer: Option A


The passage states that the behaviour of the judges such as commenting on other constitutional/ statutory bodies or persons should be brought under judicial standards. This indicates that there are certain standards already existing. Hence, (A) can be inferred from the passage. Choice (B) contradicts the information given in the passage. The first sentence in the passage states that the number of instances is increasing. This statement does not mention whether it is a good sign or not. The latter statement wants this behaviour to be brought under judicial statements. From this it is clear that the assumption involved is that such behaviour is not desirable. Hence, (C) is the assumption implicit in the passage. The passage is referring to passing particular kind of comments but it is not against every kind of comment. Hence, (D) cannot be concluded. Choice (A) is the inference.

B. The government should ask the drug peddlers to not to sell drugs to high profile people.

C. The government should declare consumption of drugs as illegal.

D. The Prime Minister should call for meeting of all high profile people in the society to discuss the matter.

Answer: Option A


The statement brings out the reasons behind the government’s failure to curtail drug menace. As the people involved are high profile people, it is possible that the efforts of the enforcement authority do not run smoothly. Choice (1) states that the government should increase its support to the enforcement authority. This would help them to perform their duty properly. Hence, (1) is proper course of action. Choice (2) is meaningless as the government does not support selling of drugs at all. Choice (3) is based on the assumption that drug abuse is not declared illegal. Hence, (3) is not a proper course of action. It is meaningless to have meeting with those who are actually involved in illegal activity to discuss about such activity. Hence, (4) is not a proper course of action. Hence, Choice (1) is proper course of action.
