The Correct Option is D
Solution and Explanation
The series \( S_1 \) consists of five terms: \( \{a, b, \frac{a}{2}, d, a + 20\} \). To calculate the average value of the terms in \( S_1 \), we first need to find the sum of these terms.
The sum is:
\[
\text{Sum of terms} = a + b + \frac{a}{2} + d + (a + 20)
\]
Since the terms of the series are not explicitly defined, and no values are provided for \( a \), \( b \), and \( d \), it is not possible to calculate a precise average. Therefore, we conclude that the average is not an integer. Thus, the answer is: d. Average is not an integer.

Scientific research shows that many animals are very intelligent and have sensory and motor abilities that dwarf ours. Dogs are able to detect diseases such as cancer and diabetes and warn humans of impending heart attacks and strokes. Elephants, whales, hippopotamuses, giraffes, and alligators use low-frequency sounds to communicate over long distances, often miles. Many animals also display wide-ranging emotions, including joy, happiness, empathy, compassion, grief, and even resentment and embarrassment. It’s not surprising that animals share many emotions with us because we also share brain structures, located in the limbic system, that are the seat of our emotions.- CAT - 2024

Lyric poetry is a genre of private meditation rather than public commitment. The impulse in Marxism toward changing a society deemed unacceptable in its basic design would seem to place demands on lyric poetry that such poetry, with its tendency toward the personal, the small scale, and the idiosyncratic, could never answer. There is within Marxism, however, also a strand of thought that would locate in lyric poetry alternative modes of perception and description that call forth a vision of worlds at odds with a repressive reality or that draw attention to the workings of ideology within the hegemonic culture. The poetic imagination may indeed deflect larger social concerns, but it may also be implicitly critical and utopian.- CAT - 2024
