126. Often, crimes are characterised as either malum in se — inherently evil — or
malum prohibitum — criminal because they are declared as offences by a
legislature. Murder is an example of the former. Failing to file a tax return illustrates the latter. Some jurisdictions no longer distinguish between crimes malum in se and malum prohibitum, although many still do. From the information given above, it can be validly concluded:
(a) Many jurisdictions no longer distinguish between crimes malum in se and malum prohibitum.
(b) Some jurisdictions still distinguish between crimes malum in se and malum prohibitum.
(c) Some crimes characterised as malum in se are not inherently evil.
(d) Some crimes characterised as malum prohibitum are not declared by a legislature to be an offence.
127. A trucking company can act as a common carrier — for hire to the general public at published rates. As a common carrier, it is liable for any cargo damage, unless the company can show that it was not negligent. If the company can demonstrate that it was not negligent, then it is not liable for cargo damage. In contrast, a contract carrier (a trucking company hired by a shipper under a specific contract) is only responsible for cargo damage as spelled out in the contract. A Santa Inc. tractor-trailer, acting under common carrier authority, was in a 5-vehicle accident that damaged its cargo. A Banta Inc. tractor-trailer, acting under contract carrier authority, was involved in the same accident, and its cargo was also damaged.
From the information given above, it can be validly concluded that, in reference to the accident,
(a) if Santa Inc. is liable, then it can show that it was not negligent.
(b) if Santa Inc. cannot show that it was not negligent, then it is not liable.
(c) if Santa Inc. can show that it was not negligent, then it is not liable.
(d) if Banta Inc. is liable, then it cannot show that it is negligent.
128. A rapidly changing technical environment in government is promoting greater reliance on electronic mail (e-mail) systems. As this usage grows, there are increasing chances of conflict between the users’ expectations of privacy and public access rights. In some investigations, access to all e-mail, including those messages stored in archival files and messages outside the scope of the investigation, has been sought and granted. In spite of this, some people send messages through e-mail that would never be said face-to-face or written formally.
From the information given above, it cannot be validly concluded:
(a) Some e-mail messages that have been requested as part of investigations have contained messages that would never be said face-to-face.
(b) Some messages that people would never say face-to-face are sent in e-mail messages.
(c) Some e-mail messages have been requested as part of investigations. (d) E-mail messages have not been exempted from investigations.
129. Priya T. is a former government employee who was entitled to benefits under the Government Employee Compensation Act because of a job-related, disabling injury. When an eligible government employee has such an injury, the benefit is determined by this test: If the beneficiary is married or has dependents, benefits are 3/4 of the person’s salary at the time of the injury; otherwise, benefits are set at 2/3 of the salary. Priya T.’s benefits were 2/3 of her salary when she was injured.

(b) was not married and had no dependents
(c) was not married but had dependents
(d) was married and had dependents

SECTION IV: REASONING
106. Devil turns 270 + 180 – 90 = 360° in clockwise direction and faces north-east again. But, it is not given that Himanshu is facing towards Devil or away from Devil. Therefore, it cannot be determined in which direction is Himanshu facing. Hence, (d).
107. The original number: 8314629
After arranging the digits in descending order: 9864321
In both cases, only one digit is between 9 and 6. Also, in both cases there are 2 digits between 9 and 4. Thus, two such pairs are possible. Hence, (a).
108. A + 6 = G + 5 = L + 4 = P + 3 = S. Thus, S + 2 = U. Hence, (b).
109. 2 = 12 + 1, 12 = 32+ 3, 30 = 52 + 5, _, 90 = 92 + 9, 132 = 112 + 11
Thus, missing term is: 72 + 7 = 56. Hence, (c).
110. These are squares of consecutive prime numbers: 22, 32, 52, 72, 112, 132. Thus, next term is 172 = 289. Hence, (a).
111. HEAD = 8514, i.e. position of letters in alphabetical order. Thus, FADE will stand
for 6145. Hence, (b).
112. My father’s mother’s only child is my father. My father’s son’s brother is in the photograph. Hence, he is Rahul’s brother. Hence, (a).
113. Anita, Babita and Cabita are children of Dambru. Thus, Dambru could be the father or mother of Anita as it is not given whether Dambru is a male or a female. Hence, (d).
114. The number after % sign is divided by the number preceding the sign. 2/1 = 2,
16/4 = 4, 9/3 = 3. Thus, 4%20 = 20/4 = 5. Hence, (b).
115. q = |
Here, m = 10 and h = 1. Substituting, we get – q = | = 25
Hence, (b).
116. (b) Not every ambitious person wants to be greatness, so some ambitious persons will not seek greatness
These two circles show that some ambitious persons are not those who seek greatness.
117. (a) Only A is B can be interpreted as All B is A so All who enjoy magic are sorcerers.
Above circle shows that as every sorcerer enjoys magic then some sorcerer will definitely enjoy magic.
118. (a) A only if B can be interpreted as If B then A. Something is a reptile only if it is cold-blooded means if it is a reptile then it is coldblooded so A reptile is cold bloooded.
................Above circle can be drawn from the given statement. Hence illustrates answer (a).
119. (d) Almost = Some. so Some patients will be home within 48 hours.
................Above circle can be drawn from the given statement. Hence illustrates the answer.
120. (a) None but top = only top. So only top students will be accepted to NLS so All persons in NLS are top students.
Above circle can be drawn from the given statement. Hence illustrates the answer
121–122.

121. (b)
122. (d) one day
123. (d) The question mark should be replaced by “PST”.
D + 6 = J + 6 = P + 6 = V
G + 6 = M + 6 = S + 6 = Y
H +6 = N + 6 = T + 6 = Z
124. (b) 96 16 81
96/16 [Use Rule (II)]
= 6 81 [Use Rule (III)]
81 – 6 = 75 x = 75
Again,
11 15 18 [Use Rule (I)]
11 x 15 = 165 18 [Use Rule (IV)]
165 + 18 = 183 y = 183
Now, y – 2x = 183 – 2 x 75 = 33
125. (d) 28 49 13
(49 – 28) 13 [Use Rule (III)]
21 13 [Use Rule (I)]
= 273 x = 273
Again,
37 12 22
(37 + 12) 22 [Use Rule (IV)]
49 22 [Use Rule (IV)]
49 + 22 = 71 y = 71
Now x + y = 273 + 71 = 344
126. (b) From the following statement ' Some jurisdictions no longer distinguish between crimes malum in se and malum prohibitum, although many still do.' we can conclude that some jurisdictions even now distinguish between crimes malum in se and malum prohibitum.
127. (c) If Santa Inc. can show that it is not negligent , then it will not be liable. This can
be concluded from ' As a common carrier, it is liable for any cargo damage, unless the company can show that it was not negligent.'.................
128. (a) A,C and D can be concluded and only B cannot be validly concluded as it is already mentioned explicitly in the passage.................
129. (b) Since priya got 2/3rd of her salary, so it can be concluded that she is neither
married nor has dependants.
130. (d) A cannot be concluded as the argument mentions other professions. B is not possible as we don't know if all the nurses were immigrants, we just know some immigrants were nurses. C is false. So only D is possible.
131. (a) A. All + No = No => Hence no IITs are BITS.
B. All + No = No => Hence no BITS are IITs.
132.................All citizens speak truth + Some young are citizens = Some young speak truth.
Therefore answer is (c)
133.................No mammal is oviparous + some creatures are oviparous = Some creatures are not mammal. Those creatures which are oviparous are not mammals.
Hence answer is (c).
134. (b) All giants climb beanstalk + some chicken do not climb beanstalk = some
chicken are not giants. Hence answer is (b).
135. No bulls eat grass+ All matadors eat grass = No matadors are bulls. Some skunks drive cadillacs + All skunks are polar bears = Some polar bears drive cadillacs.
................Hence option (d).
136. As one member in consecutive skits must be common, thus (c) is a possible case.
Hence, (c).
137. Since Salma appears alone in first and fourth skit, she must appear in second and
third skit to have a common member. Hence, (a).
138. If Riya appears in three skits, then Salma appears in 4 and Tina in 5 skits. In this case, all three can appear together in three skits. Hence, (d).
139. To satisfy the condition, Tina must appear twice and Riya and Salma four times.
In this case none of the statements would be definitely true. Hence, (d).
140. Either of Salma or Tina must be cast in the first two skits to get a common member. Hence, (d).
