Final

Due Thursday 12/17, to CollectIt by 11:45pm (pdf only).

This exam counts for 35% of your course grade.

No late finals will be accepted.

Note: You may not discuss the final with other students (until after everyone has turned it in). Please send any questions about the final directly to me (via email) rather than posting on GoPost. I will respond by email and post answers as appropriate on the GoPost. Please read GoPost.

Note 2: Finals will be graded exactly as turned in via CollectIt. It is the student's responsibility to double check that the pdf file is correct and legible.

Problem 1. A Tree (70pts)

A. Draw a tree for the following sentence, using the grammar from the textbook (Appendix A plus the lexical rule given in the answer key to Ch 11, Problem 5 from HW 6.) and according to the instructions below. (NB: This problem is not only about long distance dependencies, but also about multiple phenomena involving the rules and principles of our grammar.)

• These pets I believe are expected to live long and to be simple to care for.

Instructions

1. Show the whole tree (i.e., no triangles under nodes). Specific tips:
   • Five different phrase structure rules are used, one nine different times. [Hint updated 12/12/15]
   • Use CONJ as the abbreviation for a feature structure that is [HEAD conj] and ADV for a feature structure that is [HEAD adv].
2. Assume lexical entries for the words instantiating appropriate types from the grammar. Specific tips:
   • There is one orv-lxm.
   • There is one easy-type adjectives.
   • Assume that care is a piv-lxm that selects for an argument-marking PP headed by for as its complement.
   • Assume that long is an adverb.
   • You are not asked to show ARG-ST values, but it may be helpful to work out what they are.
3. Label each node with an appropriate abbreviation (e.g., NP).
4. Show the values of SPR, COMPS, MOD, GAP, and STOP-GAP where they are non-empty. These values should include tags where they are identified with other structures in the tree (whole nodes or the value of SPR, COMPS, MOD, GAP and/or STOP-GAP on other nodes). At least one instance of each tag should be associated with a category abbreivation (e.g. NP). If the grammar requires coindexing (but not complete identification), show that with a subcript (NP_i).
5. Please do NOT show the value for any other features. The tree is big enough as it is!
6. Check your work: The correct tree has 30 nodes, not counting the leaves (word forms). I found 39 non-empty values for SPR, COMPS, MOD, GAP and STOP-GAP collectively. I used tags numbered 1-15, plus the index i. (You don't have to use the exact same numbers in the same places; this is meant to help you check that you have the right number of sets of identities.)

B. Describe each step in the cascade of identities that link the INST value of the pet predication to the CARED value of care-for predication. Your answer should take the form of an enumerated list. Each item in the list should describe one step, i.e., state which features are required to have the same value and state which lexical entry, rule or principle of the grammar requires this.

I found 38 steps in this chain. You do not need to mention any lexical rules, nor any specific lexical types. Identities that come from either can be described as enforced by the lexical entries themselves. You should, however, account for identities required by the ARP (I found 11 of those).

Please format your answer as a table, following the example below, where I given you the first and last few links in the chain, plus some from the middle. (NB: The assignment of members of the identity as 'first' and 'second' is arbitrary, and either order is acceptable. Similarly, the steps can be listed in any order, though the problem should be easier if you follow the chain step by step. Step N+1 was updated on 12/14/15)

	Grammar entity (lex entry, phrase structure rule, principle)	First member of identity	Second member of identity
1.	Lexical entry for pet	The INDEX value of N pets	the INST value of the pet predication
...
N.	Valence Principle	SPR value of VP expected to ... for	SPR value of the V expected
N+1.	ARP	SPR value of the V expected	first element of the ARG-ST list of the V expected
N+2.	Lexical entry for expect	first element of the ARG-ST of the V expected	SPR value of second element of the ARG-ST of the V expected
N+3.	ARP	second element of the ARG-ST of the V expected	sole COMPS element of the V expected
...
36.	HCR	sole COMPS element of the V care	PP for
37.	ARP	second element of the ARG-ST of the V care	sole COMPS element of the V care
38.	Lexical entry for care	INDEX value of the second element of the ARG-ST of the V care	CARED-FOR value of the care-for predication

Problem 2. Some Lexical Rules (30pts)

A. For each word in the following sentence, list the lexical rules involved in licensing its word structure. (Again, this question is cumulative, and not about any one particular phenomenon. Once again, use the grammar in Appendix A for reference. Also, while you do not need to provide a tree for your answer, it might help you work through the problem to sketch one out.)

• Didn't Sandy expect it to surprise Kim that the team won?

Check your work: Though there are 11 words in the sentence, they collectively represent 14 applications of lexical rules. One lexical rule is used 5 times.

B. Show the word structure for Didn't as it appears in this sentence. Include the effects of the lexical rule(s) it undergoes as well as constraints inherited from types (e.g., those on auxv-lxm and its supertypes, as well as those on word). You don't need to show the RESTR values of the elements of the ARG-ST and valence lists or any other information that is underspecified by the combination of the lexical entry and lexcial rules but rather `unifed in' from other parts of the tree.

C. How does our analysis capture the fact that expected cannot appear instead of expect in this example? That is, why is the following ungrammatical?

1. *Didn't Sandy expected it to surprise Kim that the team won?

   How does our analysis capture the fact that there cannot replace it?

2. *Didn't Sandy expect there to surprise Kim that the team won?
