I feel the question is really unclear. What syntax is it expecting?
I could write a basic component in my sleep, but I feel the editor or test suite is set up for a particular method. Does it want onChange or onClick? Event or e? Does it want me to name it something? I've been trying for ages to get something through but there's not even an error window to view the logs.

That particular quiz seems to be looking for the "onChange" method in the section that I think you're referring too.
