Problem 1:

For each of the ambiguities listed below, explain how it can be disambiguated using either selectional restrictions, frequency in context (for lexical ambiguity), or world knowledge. If disambiguation is possible using selectional restrictions, you should prefer this to the other two, as selectional restrictions are usually both stronger and easier to implement. If you use selectional restriction, explain what are the features, the relation, and the constraint involved. If you use frequency in context, explain how the context is established by other parts of the sentence. If you use world knowledge, explain the rules being used. For example:
