JetBlue accepts Diagnostic Specimens for transport. JetBlue ______ carry any substance which is known to or may have a serious human or animal disease.

• A. may
• B. will not
• C. could
• D. will

Answer: (B)

The main idea is that airlines enforce a firm safety rule against transporting materials that could spread disease. Saying JetBlue will not carry any substance known to or possibly carrying a serious human or animal disease communicates a definite prohibition, which is how safety policies are written. Using may or could would imply it might be allowed, which weakens the safety stance. Saying will would assert they do carry such substances, which contradicts the protective purpose. So the best choice expresses a clear, uncompromising safety rule: JetBlue will not carry any substance that could pose a serious health risk.
