Identification of Sentence Fragment

1. Definition of Sentence Fragment: A sentence fragment is a group of words that does not express a complete thought. It typically lacks either a subject, a verb, or does not provide a complete idea.

2. Analysis of the Given Sentence: The phrase "Until the variable harlequin toad was rediscovered in a remote mountain region of Costa Rica" starts with the conjunction "Until." This implies that it is dependent on another clause to form a complete thought.

3. Complete Thought Requirement: For the fragment to be a complete sentence, it would need an independent clause that gives a complete idea. An example could be "Until the variable harlequin toad was rediscovered in a remote mountain region of Costa Rica, scientists were worried about its extinction."

Conclusion

The given phrase is indeed a sentence fragment because it does not stand alone as a complete thought. It needs an additional clause to become a complete sentence.
