Statement:
Anger is energy, in a more proactive way and how to channelize it is in itself a skill.
Assumptions:
I. Anger needs to be channelized.
II. Only skillful people can channelize anger to energy.
Answer: B
In this the author has not clearly stated whether there is a need to channelize anger in to energy or not. So, I is irrelevant.
In the statement II it is given that channelizing anger to energy is a skill. Here the assumption of the author is that only those people who have the skill can channelize anger to energy.
Only II is implicit.
