I am reposting this because I did not receive an answer and am still stuck.
(a) The lexicon and phrase structure grammar cannot provide
hierarchical structures (i.e., trees) for sentences such as the following:
-A lion escaped from the zoo yesterday.
-An eagle flew away quickly.
State additions to the lexicon and grammar that will provide complete trees for these
sentences, and draw the two trees.1
(c) For each of the following sentences, indicate whether it has a complete hierarchical structure according to the revised lexicon and grammar (yes/no).
-A cute lion escaped from the zoo yesterday.
-An cute lion escaped from the zoo yesterday.
-A gray eagle flew away quickly.
-An gray eagle flew away quickly.
(d) Suppose we would like to modify the lexicon and grammar so that the ungrammatical sentences above do not have complete tree structures. Could we do this by only splitting each of the syntactic categories Determiner and Noun into two subcategories and revising the
phrase structure rules that refer to Determiner and Noun? (explain why or why not)
