Question

is there a sentence fragment? when it comes to seafood, americans arent always eating what they think they are. according to an fda report based on dna analysis of fish that are frequently misidentified. yes no

Explanation:

The second "sentence" ("According to an FDA report based on DNA analysis of fish that are frequently misidentified.") lacks a main verb and a complete thought, making it a fragment. The first is a complete sentence, but the second is not. So there is a sentence fragment.

Answer:

yes
