1. Direct Speech:	e.g., “Can I have some cake?” or “Who is the cake for?”
2. Indirect Speech:	e.g., “She is asking her mother if she can have some cake.” or “Who the cake is for.”
3. Partially Indirect/Mixed:	e.g., “Can she go eat cake?” (where the response seems to have features of both direct and indirect speech forms)
4. Ambiguous:	e.g., “Eat cake.” (where the response doesn’t fit clearly into any of the above three categories)
