Clauses thus it is not the next available position

clauses. Thus, it is not the next available position causing issues. Additionally, wh words in the sentential
subjects (8f~g) are moved outside of the TP, which violates the generalization made. The M Hypothesis
offers a valid explanation on why wh words have limited movement and cannot appear in certain places
while the N Hypothesis does not. These results suggest that wh words move, as they can be blocked,
instead of teleporting—a suggestion that aligns with the structure proposed by (2b) and contradicts the
structure of (2a). This data thus favors the M Hypothesis because blocking movement can occur and
refutes the framework of the N Hypothesis.

5. Test 4: Multiple Wh Words
Previously, only one wh word appeared in a sentence at a time, but grammatical sentences can be
formed in the presence of multiple wh words . English allows for the coexistence of multiple wh words ,
although only in certain conditions. The sentences below show examples of multiple wh words occurring:
(9) a. Yuri picked a carrot in the garden. i. *Where what did Yuri pick?
b. Where did Yuri pick a carrot? j. *Who where picked in the garden?
c. What did Yuri pick in the garden? k. Who picked what where?
d. Who picked a carrot in the garden? l. Where did who pick what?
e. Who picked a carrot where? m. *What who picked where?
f. Who picked what in the garden? n. *Who where picked what?
g. What did Yuri pick where? o. *What where who picked?
h. Where did Yuri pick the what?
The sentences in (9a~o) show the process of replacing elements in a sentence with wh words . (9a)
shows the base sentence which is grammatical because no replacements have been performed on it.
(9b~d) illustrates replacing a single element with a wh word which results in grammatical sentences as
discussed in Test 1 - Complements of Verbs. Beyond single replacement, sentences (9e~n) show
replacement of up to three wh words . In (9e~j), notice that two wh words are being replaced. In (9e~h),
grammatical sentences are present and each wh word is in their own respective place. Even in (9g~h)
where the wh words move, grammaticality is retained since it respects the positions of previous wh words .
However, as seen in (9i~j), ungrammaticality can arise when the positions of wh words are not respected.
In (9i), “where” and “what” are competing for the same CP specifier causing ungrammaticality; a similar
situation occurs in (9j) with “who” and “where.” Continuing into three word replacement, observe that in
(9k) it is possible to replace all elements in a sentence like “Yuri,” “a carrot” and “the garden” with
