wishy-washy world
As I explained, with historical and technological analogs, your set of possible answers is inappropriate for the question.
if you want me to pick the CLOSEST answer, for 1) the answer is a) and the rest of the poll collapses into a singularity.
Anyway, as I pointed out, question 1 is actually so badly worded that it is asking two very different things simultaneously. How will interpret the answers?
(BTW, SM, the real world *is* fuzzy and imprecise, which is why you have a history of supplying nit-pickingly precise solutions that don't work, and then spend pages of reposts reworking aspects of the problem without addressing the fundamental erroneous assumptions that underly your misleadingly precise "solution")
