The correct answer is: C. Either I or II follows
The statement “This world is neither good nor evil; each man manufactures a world for himself” means that the world is neutral and that people’s perceptions of the world are subjective. This means that both conclusion I and conclusion II are possible.
Conclusion I: Some people find this world quite good.
This conclusion is possible because people’s perceptions of the world are subjective. Some people may find the world to be a good place, while others may find it to be a bad place.
Conclusion II: Some people find this world quite bad.
This conclusion is also possible because people’s perceptions of the world are subjective. Some people may find the world to be a bad place, while others may find it to be a good place.
Therefore, both conclusion I and conclusion II are possible.
