Recently, the answers to a test held nationwide were leaked to a group of unscrupulous people. The investigative agency has arrested the mastermind and nine other people A, B, C. D, E, F, G, H and I in this matter. Interrogating them, the following facts have been obtained regarding their operation. Initially, the mastermind obtains the correct answer key. All the others create their answer key from one or two people who already possess the same. These people are called his/her "sources".
If the person has two sources, then he/she compares the answer keys obtained for both sources. If the key to a question from both sources is identical, it is copied, otherwise it is left blank.
If the person has only one source, He/she copies the source's answer into his/her copy. Finally, each person compulsorily replaces one of the answers (not a blank one) with a wrong answer in his/her answer key.
The paper contained 200 questions, so the investigative agency has ruled out the possibility of two or more of them introducing wrong answers to the same question. The investigative agency has a copy of the correct answer key and has tabulated the following data. This data represents question numbers.
| Name | Wrong Answer(s) | Blank Answer(s) |
| A | 45 | - |
| B | 96 | 46,90,25 |
| C | 2756 | 17,46,90 |
| D | 17 | - |
| E | 4690 | - |
| F | 1446 | 92,90 |
| G | 25 | - |
| H | 4692 | - |
| I | 27 | 17,26,90 |

The question in this section is based on the passage. The question is to be answered on the basis of what is stated or implied in the passage. For the question, more than one of the choices could conceivably answer the question. However, you are to choose the best answer; that is, the response that most accurately and completely answer the question.
Most people acknowledge that not all governments have a moral right to govern and that there are sometimes morally legitimate reasons for disobeying the law, as when a particular law prescribes behaviour that is clearly immoral. It is also commonly supposed that such cases are special exceptions and that, in general, the fact that something is against the law counts as a moral, as well as legal, ground for not doing it; i.e., we generally have a moral duty to obey a low simply because it is the law. But the theory known as philosophical anarchism denies this view, arguing instead that people who live under the jurisdiction of governments have no moral duty to those governments to obey their laws. Some commentators have rejected this position because of what they take to be its highly counter-intuitive' implications:
(a) that no existing government is morally better than any other (since all are, in a sense, equally illegitimate), and
(b) that, lacking any moral obligation to obey any laws, people may do as they please without scruple. In fact, however, philosophical anarchism does not entail these claims.
First, the conclusion that no government is morally better than any other does not follow from the claim that nobody owes moral obedience to any government. Even if one denies that there is a moral obligation to follow the laws of any government, one can still evaluate the morality of the policies and actions of various governments. Some governments do more good than harm, and others more harm than good, to their subjects. Some violate the moral rights of individuals more regularly, systematically, and seriously than others. in short, it is perfectly consistent with philosophical anarchism to hold that governments vary widely in their moral stature.
