A chemical engineer should express a professional opinion only when both of the following are true: he is adequately informed of the facts and the purposes for which the opinion is asked are known.

• A. A and b
• B. A only
• C. B only
• D. None of the above

Answer: (A)

Giving a professional opinion hinges on two essential checks: you must be fully informed of the facts and you must understand why the opinion is being sought. Being adequately informed means you know the data, assumptions, uncertainties, and technical details that affect the issue at hand. Knowing the purpose means you understand what decision will be made with your opinion, the scope of what you’re being asked to address, and the limits on how your input should be used. When both conditions are met, you can apply your professional judgment responsibly, clearly communicate the basis and limitations of your view, and anticipate how uncertainties might influence the outcome. If facts are missing, the opinion might be incomplete or misleading. If the purpose isn’t known, the opinion could be misapplied or inappropriately tailored to suits a particular aim, which can undermine safety, ethics, and accountability. Thus, the best choice is the one that requires both being adequately informed and understanding the purpose. Options that require only one condition or none fail to protect the integrity and value of a professional opinion.
