deletion hypothesis in a sentence

1. Hence, PF-deletion hypothesis generates sloppy readings because it treats the elided VP as identical structures to the antecedent VP and co-indexation is constrained by locality.
2. The PF-deletion hypothesis assumes the elided VP is fully syntactically represented but deleted in the phonological component between SPELLOUT and PF . It suggests that VP deletion is the process that generates sloppy identities because binding conditions.
3. This hypothesis claims that before SPELLOUT, the elided VP has no structure and exists as an empty or null VP ( as opposed to the PF-deletion hypothesis, which asserts that the elided VP has structure throughout the derivation ).
4. It's difficult to find deletion hypothesis in a sentence.
