Answer 1

Answer:

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

Step-by-step 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.
