Opening activity

I found out that all the students have done a questionnaire in its different ways , as an online or in a restaurant and even get asked by another student ,however one of the students didn't experience being asked questions on phone because in his opinion it is an annoying thing, because he believes that they do there phone calls in an inappropriate time. But regarding the researching by using the internet or the library to search informations ,i found out that the majority of the students actually done this and they also took a part in an interview for researches.
