There are a couple of ways to approach this, mostly depending on those
multiple options and how you want to deal with them.
You could use checkboxes and/or radio buttons from the Forms toolbar (View
--> Toolbars --> Forms) and later you can examine the related cells for those
controls to compile the results of your surveys.
Or you could use Data Validation in cells to provide lists for the survey
takers to choose from and later examine those cells to compile the results of
the survey forms.
If you can be a bit more specific about the types of entries, numbers of
choices and things like that, we may be able to offer more assistance.
