80 percent correct.
100 percent irritated at the misleading, entrapping wording of the questions. [/voice of science student]
For those questions that were missed, I followed up on the "explanation". This led to further understanding, including a couple of mea culpas on the test writers' part indicating that terminology was a major sticking point for many people. Full credit for inspiring further discussion. [/voice of science teacher]
