Can you help me understand this English question?
Post the draft of your technical definition. Make sure that you have definitions of both a concrete noun (physical object) and an abstract noun (idea or concept) and that each definition has a two-part structure: formal definition followed by extended definition. Ideally, your concrete and abstract nouns should be linked; that is they should pertain to same profession or activity.
Ideally, you should post your draft as early in the week as possible, to receive maximum feedback from students.
NOTE: Do not provide a Description of a Mechanism! That will be your next written assignment!
