A sentence is ambiguous when it has more than one meaning. There are two main types of ambiguity: Lexical or Semantic Ambiguity (one word in the sentence having more than one meaning) and Structural or Syntactic Ambiguity (This type of ambiguity results from a phrase in the sentence having more than one possible structure. Each possible structure is associated with a different meaning.) The following sentences may be lexically or structurally ambiguous, or both. Identify the ambiguity in the following sentences and provide paraphrases showing that you comprehend all the meanings
