translate the following sentences: (i) Mary has a false passport. F(m,p) (F=False, m=Mary, p=Passport) (ii) Peter likes nobody but himself. (iii) Mary only dates Americans. (iv) Smoking is dangerous. D(s) (D=dangerous, s=Smoking) (v) Not everybody cooked their own dinner. ¬?x (C(x) > D(x,x)) (C=cooked, D=dinner) (vi) Sally wore a beautiful dress. ?x(S(x) ^ (W(x,d) ^ B(d))) (S=sally, W=wore, d=dress, B=beautiful) Unsure of the translations, any help would be great!

As a general remark, a translation into predicate logic depends completely on the chosen predicate symbols and constants. We could translate any sentence into just P if such symbol P is available. Quote:
