Critical Reasoning (CR) | Re: A medical journal used a questionnaire survey to determine whether

i went with A and here follows my line of reasoning.
A-Lets assume there were 1000 readers/ readers who received the questionnaire. 900 returned and out of which 62% supported then approximately 558 persons supported- i felt this is better
B- other journals - None of my business
C- i rejected this option bec we know nothing about the people who would have liked the format change but would not have returned the questionnaire. lets say 1000 readers surveyed out of which 200 only returned the questionnaire.
