Primary research plans

My subjects for my survey will be around 25-60 9th graders at decatur high school. I will hand out a written questionnaire. Shown below. 

Japanese Language survey-

• Have you been exposed to Japanese? in what way? (TV show, family member, friend, trip,etc...)
  
• Would you be able to tell the difference between japanese and other languages (such as chinese, korean,etc..) from hearing it? from seeing the written characters? 
  
• Would you be interested in learning more about the japanese language and it's history?
  
• What would you like to know?
  
• What sort of prior knowledge do you have about Japanese? If any, please list some information.
