Two systems of "Remnant Movement II" and extraction from Specifier position

Inspired by Kayne's Antisymmetry hypothesis, there have been over the last decade numerous analyses employing extensive remnant movement, among which the Koopman & Szabolcsi (2000) analyis of Hungarian and Dutch and the Rackowski & Travis analysis of Malagasy. In particular, R&T's approach solves several outstanding puzzles of Malagasy syntax, but runs into a possible contradition with regard to the proper placement of arguments and adverbials, namely needing extraction out of deeply embedded specifier positions in some cases and wanting to forbid it in others. It turns out that this problem is found in K&Sz's analyses as well, and appears to be common to Remnant Movement approaches in general. This article discusses the two different ways of solving this problem in these framework
