This image shows one of the differences in the way internal and external power express themselves in the human body. Do you know what it is?
If you do not see anything related to Internal and External power, just catalog what you see in the picture and think about it.
Since the question is about Internal and External body characteristics, what is being looked for can only involve the three human bodies in the picture. And there cannot be too many characteristics that are different between them. And of course the obvious answer, “The woman signifies Internal power simply be being a woman and the men signify External power simply by being men” is not the correct answer.
