  • d)
    EACH statement ALONE is sufficient to answer the question asked
  • e)
    Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed
Correct answer is option 'B'. Can you explain this answer?

EduRev GMAT answered  •  yesterday
To determine the value of n, we need to analyze each statement individually and then together if necessary.
Statement (1): n2 = 1
This equation can be solved as follows: n2 = 1 Taking the square root of both sides, we get: n = plus or minus 1 So, n can be either 1 or -1. This means that statement (1) alone is not sufficient to determine a unique value for n.
Statement (2): n3 = 1
This equation can be solved as follows: n3 = 1 The only real number solution to this equation is: n = 1 So, statement (2) alone is sufficient to determine that n = 1.
Conclusion
Since statement (2) alone is sufficient to determine the value of n, but statement (1) alone is not, the correct answer is:
b) Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.

Abhishek Kapoor answered  •  2 days ago
Understanding the Problem
When rolling two six-sided dice, we want to find the probability that the sum of the numbers on the dice is greater than or equal to 10.
Total Possible Outcomes
- Each die has 6 faces.
- Therefore, the total number of outcomes when rolling two dice is:
- 6 (white die) * 6 (yellow die) = 36.
Favorable Outcomes for a Sum ≥ 10
... more
Now, let's identify the combinations that yield a sum of 10 or more:
- Sum = 10: (4,6), (5,5), (6,4)
- Sum = 11: (5,6), (6,5)
- Sum = 12: (6,6)
Counting these combinations, we find:
- For a sum of 10: 3 combinations
- For a sum of 11: 2 combinations
- For a sum of 12: 1 combination
Adding these gives us:
- Total favorable outcomes = 3 + 2 + 1 = 6.
Calculating the Probability
To find the probability of getting a sum of 10 or greater, we use the formula:
- Probability = (Number of Favorable Outcomes) / (Total Possible Outcomes)
Plugging in the numbers:
- Probability = 6 (favorable outcomes) / 36 (total outcomes) = 1/6.
Conclusion
Thus, the probability of rolling a sum greater than or equal to 10 is:
- Option C: 1/6.

Pallavi Sharma answered  •  4 days ago
Understanding the Problem
We need to determine if the product of the roots p and q of the quadratic equation ax² + bx + c = 0 is greater than 0, given that a, b, and c are non-zero.
Key Concept
The product of the roots of a quadratic equation is given by the formula p*q = c/a. To determine if p*q > 0, we need to analyze the signs of c and a.
Statement (1): |p +
... more
This statement implies that both p and q have the same sign. When both roots share the same sign, their product p*q will be positive.
Thus, statement (1) alone is sufficient to conclude that the product of the roots is greater than 0.
Statement (2): ac > 0
This statement means that both a and c are either positive or negative.
- If both a and c are positive, then p*q = c/a > 0.
- If both a and c are negative, then p*q = c/a > 0.
In both cases, the product p*q is greater than 0, making statement (2) alone sufficient as well.
Conclusion
Since both statements independently confirm the product of the roots p and q is greater than 0, we can conclude:
- Statement (1) alone is sufficient.
- Statement (2) alone is sufficient.
Thus, the correct answer is option 'd': EACH statement ALONE is sufficient to answer the question asked.

Film scholars agree that Hollywood portrayals of America at war follow a cyclical pattern. During and immediately after a conflict, important films trumpet glory and sacrifice. Ten to fifteen years later, questioning and sometimes pacifistic movies about the conflict dominate. In the late 1960’s, “the raging bulls” of Hollywood—the young trendsetters rising to prominence—proclaimed this pattern obsolete. However, the passage of time has demonstrated this cultural pattern to be more resilient than it seemed in those days of social change.
Throughout the majority of the last century, evidence of the cyclical portrayal of war in film abounds. After America declared war against Germany during World War I, the still infant film industry glorified the fight against “the Hun.” By the early 1930’s, major releases had changed their tone; for example, All Quiet on the Western Front put forth an anti-war message by displaying the horrors of combat. After World War II began, the industry shifted gears. Suddenly, important pictures again portrayed glories and courage without the questioning or despair. For example, Guadalcanal Diary, produced during the war, showed “the ultimate sacrifice” as a noble and undoubted good. Once again, though, by 1957, films such as The Bridge on the River Kwai won awards for depicting the moral confusion of war.
Those who later declared this pattern dead based their conviction on their hearts rather than their minds. During the Vietnam War, the only major film about that conflict was The Green Berets, starring John Wayne and far closer in tone to Guadalcanal Diary than to The Bridge on the River Kwai. Similarly, years went by before more complex visions of war, such as Apocalypse Now, and then Platoon, emerged.
While today’s film industry is more diverse and its audience more culturally fragmented, this cycle largely continues. Jarhead, a layered depiction of the first gulf war, premiered more than ten years after that conflict. Further evidence of this pattern can be seen in the release of Apocalypse Now Redux, which contained additional footage that the producers originally thought would repel audiences. Thus, the famous aphorism “The more things change, the more they stay the same” certainly applies to this aspect of the film industry.
