Consider the following Dfinite Clause Grammars (DCG):

sentence(s(NP,VP)) --> noun_phrase(NP, Num), verb_phrase(VP, Num). noun_phrase(np(D, N), Num) --> det(D), noun (N,Num). verb_phrase(vp(V,NP), Num) --> verb(V, Num), noun_phrase (NP, Num). det(d(the)) --> [the] det(d(a)) --> [a]. noun (n(bat), 5) --> [bat] noun(n(bat), p) --> [bats] noun(n(cat),s) --> [cat] noun (n(cat),p) --> [cats) verb(v(eats),s) --> [eats). verb(v(eat),p) --> [eat] Which of the following statements is true of this grammar? The grammar will not parse in Prolog as written The grammar can easily be modified to correctly handle pluralisation The grammar correctly handles pluralisation
