the cover letter could have been more informative and slightly more formal. the question "what do you think is the worst result of natural disasters?" lacks more answer options or could at least include "other." in your cover letter, you indicate that you are interested in seeing if people know about the results of natural disasters. questions like "how much do you know about how natural disasters are formed?" do not necessarily help to achieve your research objectives. other than that, this was a good attempt to create an internet survey!
i do not have anything specific in mind about this survey.
interesting and easy questions to answer, you can also find important information about natural disasters.
i think it's well done because it remains generic, but you can understand a lot by looking at the answers.
