This was probably the hardest question on the quiz. Remember Sperber &
Wilson's 2 criteria for relevance? What is most relevant is what has
(1) the largest number of implications, weighted by (2) how much effort
it requires to get those implications. So it's most implications with
least effort.

And I had also said that there was a problem with these criteria,
because we don't want large quantities of just any old implications: We
want RELEVANT implications. But "relevance" was supposed to be captured
by Sperber & Wilson's criteria. Number of implications/effor was
supposed to be the measure of the relevance. So the criteria are
insufficient.

So let's count implications, and put beside them (in parentheses) the
relative amount of effort

A: 1 (0 minutes effort)
B: 36 (18 minutes effort)
C: 18 (9 minutes effort)
D: 6 (0 minutes effort)
E: 36 (0 minutes effort)

E gives you the most information for the least effort, but it is not
relevant to this year's quiz! Sperber & Wilson's criteria would
nevertheless pick E.

(By the way, last year's exam is not COMPLETELY irrelevant to this
year's quizzes, but that too is irrelevant, since the S & W criteria
are just pure implication/effort counters. Do look at last year's
skywriting and exam questions where the topic is relevant -- but
be sure to look at my comment on the practise answers that last year's
student gave, because my comment was meant to show what the answer would
have had to be to get a 1st.)
