assimilation and elision

This questionnaire was prepared for the learners of English (either for those who now learn it or learnt some time ago). The questions which you will be asked concern the two aspects of phonetics: assimilation and elision. The findings will be used in my yearly paper with the aim of finding out if the aspects of assimilation and elision should be included in the course of phonetics. Thank you for your help :)
The poll results are public
