This paper presents a case study of verb phrase ellipses with adverbially modified antecedents. It is shown experimentally that there is a preference for resolving ellipses in certain embedded clauses with unmodified VPs. The effect is hypothesized to reflect a general requirement to minimize the complexity of accommodated content. Four experiments support this hypothesis over plausible candidate hypotheses, including syntactic approaches to the effect (Matsuo 2001; Sailor 2014).
