Your task is to draw $4$ trees and detail the derivational process of two kinds of

interrogative sentences.

Trees $13(10$ points$)$

Draw three trees for sentence $(1),$ showing its key stages of formation:

$$ Tree #$1$ will be the BASE sentence, with no movements or tense realization.

$$ Tree #$2$ will be identical to #$1$ except that it will show DO insertion to realize

tense.

$$ Tree #$3$ will be identical to #$2$ except that it will include T$-$to$-$C movement.

$(1)$ Did the clown at the circus drive a very small car in circles?

Hint: Be sure that you diagram optional structures as adjuncts, required structures as

complements, and the nominative DP as a specifier of TP$.$ If these words are unfamiliar,

you may want to review the chapter, slides, or your notes before drawing the trees.

Tree $4(10$ points$)$

Draw a complete diagram for $(2),$ then label DO$-$insertion, T$-$to$-$C movement, and WH

movement. Assume that a very small car from $(1)$ is what the clown is driving in $(2).$ In

other words, the sentence below can describe the same situation as that from Sentence

$(1).$

$(2)$ What did the clown at the circus drive in circles?
