triggered a positive verbal screening questionnaire.

What is that? - 'I feel like crap', or something?
Seems like a pretty broad statement to call it a positive trigger based on a questionnaire.

Now, if he answered that he had just returned from Liberia from a necrophiliac convention ... Ok, I'll give them that as a reasonable basis for a 'positive trigger'...
