Premise: People who have political power see new technologies as a means of extending or protecting their power whereas they generally see new ethical arguments and ideas as a threat.

Conclusion: Technical ingenuity usually brings benefits to those who have this ingenuity while ethical inventiveness brings only pains to those with inventiveness.

Now, we want to look for the statement that most strengthens the argument.

Option A- Incorrect
This statement is not definite because we do not know according to the passage if those who offer new ways of justifying the current political power get rewarded for their innovation

Option B - Correct
This statement is the most valid statement that most strengthens the argument, and it can be seen in the passage "people with political power see new technologies as a means of extending or protecting their power". Nevertheless, they see ethical arguments and ideas as a threat.
Hence, they tend to reward people who are useful to them and punish those that they see as a threat (ref. to the passage conclusion: technical ingenuity usually brings benefits to those who have this ingenuity while ethical inventiveness brings only pains to those with inventiveness).

Option C - Incorrect
According to the passage, it was not stated if the same individual posses ethical inventiveness and technical ingenuity. Rather, we can conclude that the above stated are possessed by different sets of people.

Option D - Incorrect
There is no reference in the passage that correlates with this claim. It's wrong.

Option E - Incorrect
This is literally off point here because we cannot know from the passage if this claim is true as it wasn't stated.
