Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Analyze the statements and conclusions.
We are given two statements:
- (1) No engineer is a doctor.
- (2) Some doctors are MBAs.
From statement (1), we know that no engineer can be a doctor, so there are doctors who are not engineers. Statement (2) tells us that some doctors are MBAs, but it does not directly relate to the engineers or non-engineers.
Step 2: Analyze the conclusions.
- Conclusion I: Some doctors are not engineers. This conclusion logically follows because statement (1) tells us that no engineer is a doctor, so some doctors must be non-engineers. Therefore, conclusion I is valid.
- Conclusion II: Some MBAs are not engineers. This conclusion does not necessarily follow. While some doctors are MBAs, we do not have any direct information about MBAs being engineers or not, so we cannot conclude that some MBAs are not engineers based on the given statements.
Step 3: Conclusion.
The correct answer is (A) if only conclusion I follows, as conclusion I is valid, while conclusion II is not.

- And what are we to say of man? Is he a speck of dust crawling helplessly on a small planet, as the astronomers see it? Or is he, as the chemists might hold, a heap of chemicals put together in a cunning way? Or, finally, is man what he appears to Hamlet, noble in reason, infinite in faculty? Is man, perhaps, all of these at once?
- Life consists of puzzling questions. One cannot settle them by carrying out experiments in a laboratory, and those of an independent frame of mind are unwilling to fall back on the pronouncements of dispensers of universal nostrums. To such as these the history of philosophy supplies what answer can be given. In studying this difficult subject we learn what others at other times have thought of these matters.

- Explain the key message of the following paragraph in two lines.
For us it is above all a question of changing purpose and function of music. Not by using more and more intoxicating devices, but by using devices in a more reasonable way. What we have to do is clarify the emotions of our listeners and not confuse them. The worst thing I can think of is music that causes emotional confusion. Even that archaic, intoxicating ‘musical’ element, which all music contains, must be utilized consciously and not spontaneously.

The poet didn’t scare off when they said he was a rebel. Poetry is rebellion. The poet was not offended when he was called subversive.
