Basic vocabulary:
	Categoy	Basic Expressions
1.	N		Sadie, Liz, Hank
2.	Vi		snores, sleeps, is-boring
3.	Vt		loves, hates, is-taller-than
4.	Conj		and, or
5.	Neg		it-is-not-the-case-that

Formation rules:
1.	If  a is a Vi, then [VP [Vi a]] is a VP.
2.	If a is a Vt and b is an N, then [VP [Vt a] [N b]] is a VP.
3.	If a is an N and b is a VP, then [S [N a] [VP b]] is an S.
4.	If  a is a Neg, and b is an S, then [S [Neg a] [S b]] is an S.
5.	If  a is a Conj, b is an S and γ is an S, then [S [S b] [Conj a] [S γ]] is      an S.

Question -2 

2-21       If α is  [N ] and β is [VP ] , and if γ is [S α  β], then γ = 1 iff  [[α]]      
[[β]].

2-23  If α is [vt ], β is [N ] , and γ is [VP α  β] then [[γ]] = {x | <[[x  β]]>  [[α]]}.

2-32     If  α is [Neg ] and φ is  [s ], and ψ is  [s α  φ] then [[ψ]] = 1 iff [[φ]] = 0.

2-35  If α is  [Conj ] , φ is  [s ], ψ is [s ] and ω is [[ φ α ψ ]] then [[ω]] = 1 iff  <[[φ]], [[ψ]]>  [[α]].
