Additional adjustment to quiz

I was a bit confused when Kevin brought up the laser answer for question 13 on the quiz, because I thought I had worded the question so that the only correct one was "light & masks"...when I went back last night to check, I saw that the wording of the question was a tad subtle: "lasers & transistors" is technically incorrect, as the transistors are not *used* in the fabrication process - they are *created* during the process. I still say the correct answer is "light & masks", but because the question was tricky (and I'm not trying to be tricky), I have given a mark to those who answered "lasers & transistors" as well - the marks on Blackboard have now been updated.
