Question

is there a sentence fragment? the chicago tribune mistakenly declared thomas dewey the winner of the 1948 presidential race over incumbent harry s. truman. with the headline \dewey defeats truman\. yes no

Explanation:

A sentence fragment is an incomplete sentence that lacks a subject, a verb, or a complete thought. The second part "With the headline 'Dewey Defeats Truman'." is a fragment because it starts with a preposition ("With") and does not have a main verb or express a complete thought on its own. It should be combined with the previous sentence or revised to be a complete sentence.

Answer:

yes
