Question

is this a sentence fragment? since latrells doctor diagnosed his vitamin b deficiency and he began supplementing his diet. yes no

Explanation:

A sentence fragment is an incomplete sentence that lacks a main clause or doesn't express a complete thought. The given text starts with "Since", which is a subordinating conjunction introducing a dependent clause. There's no independent clause to complete the thought (e.g., what happened as a result of the diagnosis and supplementation isn't stated). So it's a fragment.

Answer:

yes
