HiDmitryFarber
Although I came to the right answer, I have a doubt about the -ing modifier in thisquestion:
C) .... Perrin measured the value of "Avogadro's number" using several different experimental designs.
As you can see "using" here is not precided by comma as if it modified "the value of Avogadro's number".
Am I missing something?
