then: either wh 1 or wh 2 moves to the specifier of Comp A , <strong>and</strong> the wh-phrase<br />

rema<strong>in</strong><strong>in</strong>g <strong>in</strong> situ may or may not be scope-bound by Comp or the other whphrase.<br />

(34) a.[Comp A - - - [wh 1 - - - [ wh 2 - - - ]]]]<br />

Suppose that the <strong>in</strong>-situ wh-phrase is not scope bound after movement<br />

with<strong>in</strong> (34a). <strong>The</strong>n we arrive at the representations (34b,c), which are different<br />

from each other. <strong>The</strong>refore, the <strong>MLC</strong>-respect<strong>in</strong>g structure (34b) cannot<br />

block (34c), if an application of the <strong>MLC</strong> presupposes that the relevant LF<br />

can be generated otherwise.<br />

(34) b.[wh1 [CompA - - - [wh1 - - - [ wh2 - - - ]]]]]<br />

c.[wh 2 [CompA - - - [wh1 - - - [ wh2 - - - ]]]]]<br />

Wh-phrases that are not scope-bound at all are illegal at LF. Consequently,<br />

the two partial derivations <strong>in</strong> (34b,c) will end up as grammatical only if the<br />

wh-phrase left unbound so far is later bound by a higher Comp, or by a<br />

higher wh-phrase. This is exactly what happens <strong>in</strong> (32a,b). <strong>The</strong>se examples<br />

show that neither of (34b,c) should be able to block the other. If the derivation<br />

proceeds beyond (34b,c), the cyclic nature of wh-b<strong>in</strong>d<strong>in</strong>g implies that the<br />

scope of the <strong>in</strong> situ wh-phrase must not be conf<strong>in</strong>ed to the doma<strong>in</strong> of Comp A .<br />

Suppose now that the <strong>in</strong> situ wh-phrase is scope bound after movement.<br />

This yields the representations (34d,e):<br />

(34) d.[wh1 [ Σ CompA - - - [wh A<br />

1 - - - [ wh2 A - - - ]]]]]<br />

e.[wh 2 [ Σ CompA - - - [wh A<br />

1 - - - [ wh2 A - - - ]]]]]<br />

<strong>The</strong> two syntactic objects <strong>in</strong> (34d,e) are certa<strong>in</strong>ly not identical, but they differ<br />

<strong>in</strong> a specific way only. <strong>The</strong> presence or absence of a phonetic matrix should<br />

be irrelevant for the constitution of a Logical Form. If we abstract away from<br />

the distribution of phonetic features <strong>in</strong> a syntactic object (<strong>and</strong> call the result a<br />

“partial Logical Form”), then the categories Σ are fully identical <strong>in</strong> (34d,e).<br />

Consequently, the <strong>MLC</strong> is applicable if it sensitive to the identity of the partial<br />

Logical Forms under construction, <strong>and</strong> if it selects the most economical<br />

one of the legal derivations. Normally, the <strong>MLC</strong> will pick (34d) <strong>and</strong> block<br />

(34e) because the closest phrase must be attracted. However, if there is a<br />

factor that applies cyclically <strong>and</strong> renders (34d) illegal, the <strong>MLC</strong> will let (34e)<br />

pass, s<strong>in</strong>ce there is no better compet<strong>in</strong>g structure left. <strong>The</strong> that-trace filter
