Answer

# Brief Explanations: A controlling idea should be broad - enough to encompass different aspects of the topic while also being focused. Option A presents a more comprehensive and balanced view of the impact of invention and technology (both good and bad), which can effectively guide the content of a paper. Options B, C, and D are more general statements without indicating the dual - nature of the impact. # Answer: A. Invention and technology have the power to transform in all the good and bad ways.
