When I was at work last night , I found a message on my voicemail . It was from my son 's bus driver ! I had made up a bunch of business cards for Nathan last year , that stated that he has autism , and here are some things to be aware of ( like not to touch him , he has trouble communicating when he is upset or frustrated , etc . ) I ' ve asked Nathan to give these cards to any new bus driver he has , and to substitute teachers , and to daycare people .

Question: Why would the bus driver have called and left me a voicemail ?
Answer: To get more information on understand Nathan 's condition .None of the above choices .He wanted to call me and tell me that he could n't drive someone with this condition .He wanted to complain about Nathan and his poor behavior .
