Fifteen, but I suspect there is a bias towards some other cultures than my own.
Why on earth should I want to keep a conversation going if it's not happening on it's own? The question "I find it difficult to keep a conversation going" assumes I would want to, or that it is typical to do so. Which it really isn't where I live... it's more likely to gather odd looks and short answers rather than "keep a conversation going".
Other cultural differences include "social chit-chat"...

Also, "I like to collect information about categories of things". I mean, sure, I like to collect information about categories of things like life, universe and everything, but does the question put an emphasis on "information" or "categories"? If I just like "collecting" information (although I believe the more usual term is learning), does it mean I should strongly agree? Or does it require me to be limited to certain categories (like, you know, any kind of specialization sort of requires you to do... so if you study veterinary medicine and you enjoy it, does it mean you enjoy collecting information about category of things (animals, their illnesses and their treatment), or does it mean you're a veterinary student?

I hate ambiguous and culturally aligned quizzes.
