We need to determine the passage’s tone.
- Step 1: Analyze content: The passage discusses AI’s benefits (“boosts efficiency and innovation”) and concerns (“job displacement,” “privacy invasion,” “societal risks”).
- Step 2: Evaluate tone: It presents both positive and negative aspects, suggesting a neutral stance.
- Step 3: Check options:
- (a) Entirely optimistic: Incorrect, as it mentions concerns.
- (b) Completely pessimistic: Incorrect, as it highlights benefits.
- (c) Balanced: Correct, as it weighs both sides.
- (d) Indifferent: Incorrect, as it shows engagement with pros and cons.
Thus, the answer is c.
