You are doing a case study of the death of John F Kennedy. You employ many data collection methods in creating your case study. Here is an excerpt:

John F Kennedy was assassinated on November 22, 1963 in Dallas, Texas. Of the people that I surveyed that were alive at the time, 90% of them knew exactly where they were when they heard the news. My grandmother told me that she was in a college class when the professor came in and told the class the news. A tear came to her eye when she remembered that day.

Which line reveals information obtained by a questionnaire?
