Step 1: Sentence 2 introduces the topic that the amount of published information varies by industry. The next sentence should logically explain or elaborate on this variation.
Step 2: Sentence D explains why the information varies, stating that larger, older industries with slower technological change have better published information. This makes D the logical continuation of sentence 2.
Step 3: Sentence B discusses the problem researchers face with published data being too broad or misaligned, connecting to D by elaborating on the challenges due to industry characteristics.
Step 4: Sentence A continues the idea from B, explaining that many industries do not meet the criteria (from D), resulting in limited published information.
Step 5: Sentence C introduces a solution with "however," suggesting that despite the challenges, pursuing published sources is still valuable, leading to sentence 6, which advises researchers to recognize the limitations and persist.
Step 6: The sequence BDAC forms a coherent paragraph: variation (2), reasons for variation (D), problems faced (B), limitation due to criteria (A), solution (C), and advice (6).
Verification: Other options like DABC disrupt the flow (e.g., A after D jumps abruptly to limitations without explaining the problem), and CDBA starts with a solution prematurely.
