Directions (1-5): Do as directed in each of the following questions.
1. According to Albert Einstein’s famous theory of relativity, time travel is theoretically possible. Assuming that time travel were to be made possible through some technological breakthrough, it would be advantageous to send someone back in time to prevent the assassination of Archduke Franz Ferdinand in 1914 and thus keep World War I from ever occurring.
Which of the following assumptions can be deduced from above argument?
(1) It is not possible to alter a significant current in world history merely by changing a single event.
(2) The technology necessary for time travel is likely to be developed in the near future.
(3) If Franz Ferdinand had not been assassinated, some other catalytic event would have led to the start of World War I.
(4) The assassination of Franz Ferdinand was the crucial event that triggered the start of World War I.

5. In March 1917, under pressure from communist revolutionaries, Tsar Nicholas II of Russia abdicated his throne. Sixteen months later, the Tsar and his immediate family, including Alexis, the heir apparent, were executed on orders of the new communist government because its leaders believed that all vestiges of the old regime had to be obliterated for the security of the new regime.
The leaders of the new communist government must have made which of the following assumptions?

Directions: (9 - 10): These questions are based on statement given below and the sentences labeled (A), (B), (C) and (D) as given below.
The number of people diagnosed with dengue fever (which is contracted from the bite of an infected mosquito) in North India this year is twice the number diagnosed last year. The authorities have concluded that measures to control the mosquito population have failed in this region.
(A) An effective diagnostic test was introduced about nine months ago.
(B) The incidence (number of cases per thousand) of malaria, also contracted from mosquito bites, has increased.
(C) A very high proportion of the cases were diagnosed in people of neighboring country.
(D) More cases are now reported because of increases in administrative efficiency.
9. Which of the above statements numbered (A), (B), (C) and (D) if true will weaken the given argument?
(1) Only A
(2) Only D
(3) Only C
(4) Both C and D
(5) Both A and D
10. Which of the above statements numbered (A), (B), (C) and (D) if true will most supports the given argument?
(1) Only D
(2) Only A

(5) None of these
Solutions (1-10)
1. (4) If (4) is not true we cannot reach the conclusion stated above.
2. (1) Only (1) is implicit in the given statement as it is a desired effect.
(2) and (3) are not relevant as they are neither the root cause nor the desired effect.
3. (4) Choice (4) is not even remotely related to the passage.
4. (5) (B) is extreme. (A) and (C) are relevant and preventive. Hence both are effective to solve the problem.
5. (2) Choice (2) suggests how Nicholas could have been a threat to the new regime.
Solutions (6-10):
6. (2) (A) is irrelevant and (C) supports the given argument. (B) weakens the argument by saying that since more people consume liquor in rural areas hence it is normal that the cases of food poisoning are more in rural areas. Similarly (D) also weakens the argument.
7. (3) Only (C) supports the argument saying that there are many unauthorized spurious liquor shops in the rural areas due to which the low quality liquor is supplied in rural areas.
8. (3) (1), (2) and (4) are irrelevant as nothing is mentioned about them. The district administration has issued a circular to make the farmers aware of hazards that indiscriminate use of pesticides poses to ground water and plead them to refrain from the same. Hence (3) is an assumption in the given statement.
Solutions (9-10)
The authorities conclude that measures to control mosquitoes have failed. (C) is irrelevant in the present context. (A) weakens the given argument by saying that the increase is because of the effective test and (D) also weakens the argument by saying that more cases are registered this year because of increases in administrative efficiency. However (B) supports the argument saying that as another mosquito-borne disease is increasing, it is more likely to indicate that mosquitoes are not controlled.
