Final answer:
Based on the information given, Hannah cannot be promoted at this moment as she has only three years of experience, while her firm requires four. However, since there might be other unmentioned factors or because she could reach the required experience in the near future, the accurate answer is that we cannot determine her promotion status with certainty, so the conclusion does not follow (B).
Step-by-step explanation:
The question presents a scenario involving Hannah, a solicitor with three years of experience working in a law firm that requires at least four years of experience for promotion. To determine if Hannah can be promoted, we must assess whether she meets the experience requirement stated by her firm. Since Hannah has only three years of experience and the firm requires at least four, the conclusion that she cannot be promoted yet is supported by the information provided. However, since the timeframe for promotion is not specified and we do not know when Hannah might complete her fourth year or if additional criteria need to be satisfied for promotion, it's technically correct to conclude that we cannot know for sure whether Hannah can be promoted or not at this very moment.
The logical structure indicates we should lean towards the conclusion that Hannah cannot be currently promoted based on the information given about the firm's requirements. However, the statement “We cannot know whether Hannah can be promoted or not” implies uncertainty about other factors that might influence her promotion status. Therefore, the most accurate answer to the question, based on the information provided, would be: Conclusion Does Not Follow (B), since there might be criteria for promotion beyond the years of experience or because the potential for promotion could exist in the near future once she completes her fourth year.
