Transcribed Image Text:2. Let S denotes the set of all students in your class, C denotes the set of all countries, and T(x, y)
denotes that a travels to country y.
Express each of the following statements by a simple English sentence.
Avoid symbols (e.g. a) and predicates (e.g. T(x,y)) in English sentences.
(d) VS, VS, y
(e) 3r ES, 3z ES, Vy

C, (x2) → ¬(T(x, y) ^ T(z,y)).
C, (x2) ^ (T(x, y) ⇒T(z,y)).
C, (T(x, y) ⇒T(z,y)).
