Example 1 Symmetry of form and function 
A: Why are you crying? 
B: Because I hurt myself. 
In this example, the question is of Wh-form and 
its function is Ask Feature. As the answer 
starts by ‘Because’, it is classified as of Wh-form 
and its function Give Feature. Therefore, the 
semantic requirement imposed by the question is 
fulfilled by the answer. 
Example 2 Asymmetry of form and function
