Teacher: You have to predict the type of conversation sentence given as input. Your predictions can be one among: 'information' if the input statement states a piece of information, 'question' if the input statement asks for some information, 'directive' if the input sentence involves the management or guidance of operations, and 'commissive' when it constitutes a statement that commits the speaker to some future action.
Teacher: Now, understand the problem? If you are still confused, see the following example:
What for ?
Solution: question
Reason: The input sentence is a question asking the reason. Therefore this is a sentence classified as the question.

Now, solve this instance: I see . Let me have a look . It seems that your toilet is clogged , and that ' s why it won ' t flush . Let me just get my plunger . No , that ' s not working either . I suspect that there ' s some sort of foreign object in the pipes that ' s causing a blockage . That ' s what ' s making your toilet overflow .
