Which term indicates acceptable or suggested means of accomplishment?

• A. Shall
• B. Should
• C. May
• D. Must

Answer: (C)

The key idea here is how modal verbs express how strictly an option must be followed. When you see a statement that something “may be used” or that you “may” do a certain method, it means that method is allowed or considered a viable option. It signals permission and optionality, not a requirement. That’s why this term best matches “acceptable or suggested means of accomplishment”—it communicates that you have a permitted choice rather than a mandatory or recommended one. By contrast, shall and must convey obligation or a definite requirement, and should indicates a strong recommendation rather than a permission.
