30. d. The huge difference in results after the robots were reprogrammed makes dthe most logical con-clusion: Sharing information can dramatically improve the productivity of a group. Choice ais incor-rect for several reasons. First, self-interest and sharing aren’t exclusively human behaviors; animals arealso driven by self-interest, and many animals also share (information, food, etc.). Second, the robotswere programmed, not taught. The experiment doesn’t really show that the robots learnedanything;they did what they were programmed to do, and as a result, they were more successful. Choice bisincorrect because the passage does not suggest that the robots were incorrectly programmed in thefirst experiment. Nothing indicates how the researchers felt about the results, so choice cis not a logi-cal conclusion. Although the robots were far less productive when they were self-interested, choice eisnot logical because they did indeed gather some pucks and because in many instances self-interest canresult in highly productive behavior (e.g., self-preservation).
