"Can you guess..." language for exercises

[amyehodge]

I would suggest that this language be changed to something more straightforward from, for example, "
Can you guess what the regular expression ^[Oo]rgani.e\b will match?" to "What will the regular expression ^[Oo]rgani.e\b will match?"

The current language seems to imply that they'll be guessing answers instead of reasoning them out (possibly implying that they couldn't reason them out and would have to guess).

This language is throughout the 04_regular_expressions module. I haven't checked the others.
