General Manager Zhang proposes opening a branch in a new city. He sets the general principle: "A city with potential is worth establishing a presence in," then only cites favorable data such as large local population and big market, while remaining silent on the facts of two strong competitors and high cross-province management costs. From the perspective of the five-step logical closure method, what is the main problem with this report?

Answer: C

• AThe conclusion is unclear; it does not specify what kind of branch to open.✗ Incorrect. The conclusion, "opening a branch in a new city," is already clear; the problem lies not in the conclusion itself.
• BThe general principle is unreasonable; "potential" should not be the criterion for establishment.✗ Incorrect. The general principle itself has some validity; the real issue is that only facts supporting the conclusion are selected, without aligning with the complete conditions that should be evaluated according to the principle.
• COnly facts favoring the conclusion are listed, without enumerating specific facts corresponding to each condition in the principle.✓ Correct. "A city with potential" should at least include multiple conditions such as market size, competitive environment, and management costs. Zhang only discusses favorable aspects, which is a typical case of cherry-picking favorable data.
• DNo pilot or stop-loss criteria are set; if it fails, there is no way to exit.✗ Incorrect. Although checking exceptions and boundaries is important, the core deficiency described is the third step's failure to list specific facts for each condition in the principle, not the fifth step.
