The correct answer is: Only assumption I is implicit.
The statement “Success is how much a person bounces up after hitting the bottom” suggests that success is not about never failing, but about how one responds to failure. It suggests that people who are successful are able to pick themselves up and keep going after they have failed. This implies that success requires conscious efforts without being discouraged by failure.
The statement does not suggest that failure cannot be considered an acceptable thing. In fact, it suggests that failure is a necessary part of success. It is through failure that people learn and grow. Therefore, assumption II is not implicit in the statement.
In conclusion, only assumption I is implicit in the statement.
