Let T (x, y) mean that student x likes cuisine y, where the
domain for x consists of all students at your school and
the domain for y consists of all cuisines. Express each of
these statements by a simple English sentence.
e) ∃x∃z∀y(T (x, y) ↔ T (z,y))
f ) ∀x∀z∃y(T (x, y) ↔ T (z,y))

The answer is given:
e) There are two students at your school who have exactly the same tastes (i.e., they like exactly the same
cuisines).
f) For every pair of students at your school, there is some cuisine about which they have the same opinion
(either they both like it or they both do not like it).
