Any question that has an "if i do this then this will happen"
Example: If I take 3 eggs and stick them into a bowl and pour flour into the bowl as well and mix it then leave it then it will turn into a hard gooey form.
I used the word "if" to start the hypothesis and then the subject i'm trying "eggs" and "flour." I then say "Then" to signify what I think is going to happen, "It will turn into a hard gooey form."
Hope this helps and let me know how you make out on whatever you're doing!
