Alternate for Captcha - Need suggestions

 
Hi Everyone, 



We have redeveloped a website where the clients emphasis was Accessibility, but finally, due to security, they have added a Code displayed as a captcha. The use of audio captcha's is something I don't want to recommend, since the organizations works in the area of  hearing impairment and also due to the problems with sound quality, etc. 

 

I am considering suggesting a situation, where the person has to answer a question. If he can't answer, we can give an option to request another question. 

The questions would be picked randomly like 

  a.. What is the total of 2+2? 
  b.. What is the color of an apple? 
  c.. Which is the next day after Friday? 
 

Would like some opinions on this. 

 

Thanks & Regards,
