Which of the following is the assumption for the claim that 'Pleasure is desirable'?

From option 1 - The best assumption for the claim that 'Pleasure is desirable' is everyone desires pleasure. So it is correct assumption.

From option 2 - The assumption some persons desire pleasure is not correct for the claim that 'Pleasure is desirable'. So it is not correct assumption.

From option 3 - The assumption everyone desires something is not correct for the claim that 'Pleasure is desirable'. So it is not correct assumption.

From option 4 - The assumption pleasure is essential is not correct for the claim that 'Pleasure is desirable'. So it is not correct assumption.

Hence, "option 1" is the correct answer.

Additional Information

1. Read the statement with an approach that the assumptions would be true with regard to the statement.
2. Do not go too logical with the statements. Analyze the given information and the assumption must only be made based on the information in the statement. Do not over-complicate it.
3. Common assumptions can always be followed but other than that do not align the statement with General Knowledge or other facts
4. Use the elimination method if you are unable to apprehend the answer. Read the statement and then the assumptions given in the options, you shall notice that a few of them will most definitely not follow. Eliminate them and then choosing from lesser options may prove to be more convenient
5. One thing to make a note of is that the assumption is something that the author believes to be true so while choosing the correct option, keep this thought in mind as well. If any option contradicts the statement, then that assumption will not follow.
