The statement is focusing on illustrating a tendency to overlook the possibility of removing things as a means of improvement, which suggests a comparison between the number of additive and subtractive suggestions.
Analyzing the provided choices:
- Choice A: States fewer than 100 suggestions were coded as subtractive, and more than 550 as additive. This effectively highlights the stark difference in the suggestions and supports the idea of people overlooking subtractive suggestions.
- Choice B: While it notes that more suggestions were coded as invalid, it doesn't effectively emphasize the focus on subtractive suggestions.
- Choice C: Provides specific numbers but doesn’t underscore the fact that the number of additive suggestions far exceeds subtractive suggestions.
- Choice D: Discusses the category of neither additive nor subtractive, which diverts the focus from the key comparison that illustrates the trend.
Given the goal of illustrating the tendency to overlook removing things, Choice A is the most effective as it directly contrasts the low number of subtractive suggestions with the high number of additive suggestions.
So the answer is: (Choice A) fewer than 100 suggestions were coded as subtractive, whereas more than 550 suggestions were coded as additive.
