   Many statements in a natural language, such as English, contain ambiguity for a variety of reasons. As humans, we can often (though not always) distinguish between possible meanings. Resovling such ambiguities is a great challenge for software.

   The [DH] text and the lecture notes discuss several sources of ambiguity. Several examples for each of these can be found in the lecture notes.

   For each of the five types of ambiguity below we want you to do the following.

   Create your own example of an English statement which has such an ambiguity. Your example must be one which was not given in the lecture notes or either of the text books.
   Justify your answer, explaining the ambiguity, and giving two or more possible interpretations of your statement.
   1. Syntactic ambiguity
   2. Semantic ambiguity
   3. The need for contextual information
   4. The need for rules of conversation
   5. The need for real-world, topical knowledge
