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 |

| F | 1446 | 92,90 |
| G | 25 | - |
| H | 4692 | - |
| I | 27 | 17,26,90 |

Political turmoil in a country is mainly caused by widespread violence and flawed economic policies of successive governments. If at all this has to be crushed, it can be achieved only by a dictatorial government which rules with iron hand. Therefore, the need of the hour is to elect a government which imposes fresh set of stringent legislations. The alternatives suggested (not necessarily all), if true, considerably weaken the argument. However, one of them is most forceful. Identify the same.
In making a decision about an important question, it is desirable to distinguish between a 'strong' argument and a 'weak' argument. A 'strong' argument must be both important and directly related to the question. A 'weak' argument may not be directly related to the question and may be of minor importance or may be related to the trivial aspect of the question. The question below is followed by four arguments numbered I, II, Ill, and IV. You have to decide which of the arguments is 'strong' and which is 'weak'.

Experts musicologists believe that Beethoven wrote his last piano sonata in 1824, three years before his death. However, the manuscript of a piano sonata was recently discovered that bears Beethoven's name and dates from 1825. Clearly, the experts are mistaken because not every piece that Beethoven wrote was cataloged in his lifetime, and it is known that Beethoven continued to compose until just weeks before his death.
The reasoning in the argument is most vulnerable to which of the following criticisms?
Vijay claimed that the large dent in the fender of the company-owned vehicle he had borrowed was caused by the careless actions of another motorist, who backed into the car when it was parked in a public garage. Yet Vijay's own car has several dents in its fenders, all of which he acknowledges as having caused by his own careless driving. Therefore, Vijay's contention that the dent in the formerly undented company-owned vehicle was caused by the careless actions of another person is not true.
The reasoning in this argument is vulnerable because of it
