Question

which is a sentence fragment? sandeep texted me the page numbers for the homework assignment. wouldnt be able to produce red blood cells without a skeleton.

Explanation:

A sentence fragment lacks a subject, verb, or a complete thought. "Sandeep texted me the page numbers for the homework assignment." is a complete - sentence with a subject (Sandeep) and a verb (texted). "Wouldn't be able to produce red blood cells without a skeleton." lacks a subject, so it is a sentence fragment.

Answer:

Wouldn't be able to produce red blood cells without a skeleton.
