The given statement is: "Be humble even after gaining victory." We need to assess which assumptions are implicit in this statement. An assumption is implicit if it logically follows from the statement.
Assumption 1: "Many people are humble after gaining victory."
This assumption suggests that there is a significant number of individuals who remain humble post-victory. The statement advises being humble, which does not necessarily imply that many people currently practice humility after winning. Therefore, this assumption is not implicit.
Assumption 2: "Generally, people are not humble."
The advice to be humble after victory does not specifically suggest that people are generally not humble. It merely provides a guideline or advice for behavior after achieving success. Thus, this assumption is also not implicit.
Therefore, neither of the assumptions can be logically deduced from the statement.
Conclusion: The correct answer is: "If neither assumption I nor II is implicit."
