Question

Which is a complete sentence? A. The sad end of a long movie. B. He could not wait long. C. Began her lessons early Tuesday morning. D. Three active boys playing on the field.

Answer 1

Among the choices, the only complete sentence is the second choice, "B. He could not wait lang.  This is a complete sentence because the thought is already complete. All the rest of the choices did not express complete thought. The subject and the predicate are also connected by a linking verb.
