Accessible 'Pick one' question with multiple lines

Hi there, 

I'm trying to design a question with three rows. Each row has three options. I.e. 
How many hours should a person work? 

The instruction is to select one option (one number of hours) per person.
Person A - 1 / 2 / 3 hours (correct response is 1 hour)
Person B - 1 / 2 / 3 hours (correct response is 3 hours)
Person B - 1 / 2 / 3 hours (correct response is 2 hours)

At the moment I created text boxes per person with triggers like:
"Change state of A2 no normal when the user clicks A1"

"Change state of A3 no normal when the user clicks A1"

Which allows me to select one number per row. 

However, one of my testers uses Jaws, and he couldn't complete the question. He said that those 1/2/3 should be radio buttons, but I can't get three options correct with ration buttons. 

My question should be fully accessible. 

Thanks for your help.
