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?

B. Of the people surveyed that were alive at the time, 90% of them knew exactly where they were
when they heard the news.

Answer 1

The line that reveals information obtained by a questionnaire is:

"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."

In this line, the author mentions that they surveyed people who were alive at the time of John F Kennedy's assassination. The information about 90% of the surveyed individuals knowing exactly where they were when they heard the news indicates that this data was collected through a questionnaire or survey. The questionnaire likely asked respondents about their personal experiences and memories related to the event, allowing the author to gather specific information about people's whereabouts during the time of the assassination.

The answer is B: Of the people surveyed that were alive at the time, 90% of them knew exactly where they were when they heard the news.

Answer 2

The correct option is;

B. Of the people surveyed that were alive at the time, 90% of them knew exactly where they were when they heard the news

Explanation:

A questionnaire is a series questions usually placed in portable written format and distributed to a target population in order to collect information and or opinions from respondents of which their response is either used in a statistical analysis or in a research

The response which is derivable from the questionnaire is therefore a proportional response with regard to a specific question.

Therefore, the best option is the percentage response of the respondents with regards to knowing their exact location when they heard the news.
