Correct answer: False

The correct answer is False because the passage likely indicates that there are more than just two exceptions to the general rule regarding federally recognized tribes' powers of self-government. Tribal sovereignty, while extensive, is subject to various limitations imposed by federal law, treaties, and court decisions, which are typically more numerous and complex than just two specific instances. Therefore, the statement inaccurately quantifies the exceptions.

Question 36: What is the value of y if y+3y+5y=18?

0
1
-2 (Correct answer)
-1

Correct answer: -2

The given equation is y+3y+5y=18. Combining the like terms on the left side, we get 9y. So, the equation simplifies to 9y=18. Dividing both sides by 9 yields y=2. However, if the right side of the equation were -18 (i.e., 9y = -18), then dividing by 9 would result in y=-2. This suggests a potential typo in the question, as -2 is the correct solution for 9y = -18.

P=16, A=1, G=7, E=5 sum to 29.

Question 43: Statement: Some kings are queens. All the queens are beautiful. Conclusion: I. All the kings are beautiful II. All the queens are kings.

Only I follow
Only II follows
Neither I or II follows (Correct answer)
Either I or II follows

Correct answer: Neither I or II follows

From 'Some kings are queens' and 'All queens are beautiful,' we can only deduce that *some* kings (specifically, those who are queens) are beautiful. We cannot conclude that *all* kings are beautiful, as there might be kings who are not queens and whose beauty status is unknown. Similarly, 'Some kings are queens' does not imply that *all* queens are kings; there could be queens who are not kings. Therefore, neither conclusion I nor II logically follows.

Question 44: In a 3-phase motor system, what indicates a 'phase imbalance'?

The motor runs at double its rated speed
The motor uses less than rated power

Question 46: The government has resorted to shock methods in recent years to combat smoking and the financial burden smokers have on the nation's economy through absenteeism and other health problems. The most recent anti-smoking advertisement featured tumors emerging from a cigarette. This advertisement was, needless to say, divisive. On the one hand, the advertisement has generated a lot of interest in the topic since it was first released and has become a viral hit. According to government estimates, the campaign will encourage some 300,000 people to try to stop smoking. However, some contend that employing a direct strategy is counterproductive because it makes people frightened. If someone believes they may have cancer or are experiencing a sign of cancer, they are prone to ignore it.

True (Correct answer)
Cannot Say

Correct answer: True

The passage explicitly states, 'According to government estimates, the campaign will encourage some 300,000 people to try to stop smoking.' This sentence directly supports the statement in the question, making it true based on the information provided in the text.

5743691
6397931
3278452
8251896 (Correct answer)

Correct answer: 8251896

This is a direct substitution cipher where each letter corresponds to a specific digit. From the examples, we can deduce: D=7, E=3, L=5, H=4, I=1 (from DELHI) and C=8, A=2, U=6, T=6 (from CALCUTA, noting L=5 is consistent). Applying these mappings to CALICUT yields 8251866. The provided correct answer, 8251896, implies that 'U' maps to '9' instead of '6', which contradicts the mapping established in CALCUTA.

24 (Correct answer)
27
25
26

Correct answer: 24

Let 'N' represent the number of new cars. Since there are four times as many used cars as new ones, there are 4N used cars. The total number of cars is N + 4N = 5N. Given that the total is 120 vehicles, set up the equation 5N = 120. Solving for N, we get N = 120 / 5 = 24 new cars.
