the merge operations should be denoted as a CP whereas in the diagram above it was an IP.
Furthermore, another operation which occurs on the adjective clause is the movement operation. According to O’Grady et al. 2005: 184, adjective clauses
structures resemble to Wh question in two respects. First, they can begin with wh word like who or which as the relative pronouns. Second, there is an empty
position within the sentence from which the Wh phrase has apparently been moved. Question number five and six required the students to figure out the
movement operation in the noun phrase [3]. These questions were intended to restate and review the students’ knowledge on CP and Wh movement principles.
[3] The car which John bought The question presented a noun phrase which was modified by an adjective clause
was only to draw the students’ attention fully on the movement operation. The tree diagram of the noun phrase [3] which students required to analyse is drawn in
Figure 4.2.
4.2 An Adjective Clause Modifies a NP

Figure 4.2 showed that the movement operation which occurred in Figure 4.2 was a NP moved to the position under the CP. It was because the nature of the
adjective clause which required to move Wh phrase under the position of CP or adjacent to the noun or pronoun which was modified.
Based on the result of the test, most of the students answered correctly. There were 37 students 82.22 stated that the movement operation which
occurred was to move the NP to CP. However, there were four students 8.89 answered that it was to move the IP to CP. It was certainly incorrect because as
Figure 4.2 illustrates, IP labeled a merger between the I and the NP which did not require any movement operations O’Grady et al., 2005: 175. Finally, there were
three students 6.67 answered that it was to move the NP to IP. They were also incorrect because it violated the rule which required to move the Wh phrase under
the position of CP not the IP O’Grady et al., 2005: 175. Moreover, the IP had already been resulted from merging the NP John and the verb bought which was
dubbed I without any movement operations. In addition, there was one student 2.22 who did not answer the question.
Question number six was still related to Figure 4.2. The figure showed that the resulted phrase after the movement operation was a CP. It is due to the fact
that the Wh phrase moved under the position of CP. It was also because the adjective clause which was marked by the relative pronoun which turned out to be
a complement of the noun phrase the car. The test revealed that there were 34 students 75.67 answered correctly by stating that the resulted phrase after the
movement operation was a CP. However, seven students 15.67 stated that the PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI

resulted phrase after the movement was an IP. This answer was incorrect because IP labels the merger between the NP John and the I without any movement
operations. Finally, there were three students 6.67 answered that the phrase which was resulted after the movement operation is a VP. This answer was also
incorrect since VP labeled the merge operation between the verb bought and the NP which before it moved. In addition, there was one 2.22 student did not
answer the question.
