JSR Notes:
Note that this is Objective level 1. This means you don't need to do much except a straight-forward definition; no explaining, no comparing and contrasting; just the dictionary definition. And note that stating what the letters of the acronym stand for is not defining. Certainly do write out the full name (or conversely give the acronym), but go on to define.
