Final answer:
In English, a phrase lacks either a subject a verb, or both, whereas a clause contains both. An independent clause can stand alone as a sentence, while a dependent clause is a secondary or subordinate thought that needs to be attached to an independent clause.
Step-by-step explanation:
In the given sentence, 'His farmhouse is located at the end of the road,' the underlined group of words is crucial in determining whether it is a phrase or a clause. A phrase lacks either a subject, a verb, or both, whereas a clause has both and can be either independent or dependent. An independent clause expresses a complete thought and can stand alone as a sentence. A dependent clause, however, cannot stand alone as it needs to be attached to an independent clause, it being a secondary or subordinate thought.
Without knowing which words are underlined, we can't definitively identify the type of group. However, one example could be 'at the end of the road,' which is a prepositional phrase as it lacks a subject and a verb. If 'His farmhouse is located' were underlined, it would be an independent clause, since it contains a subject ('His farmhouse') and verb ('is located') and can stand alone as a sentence.
