I ask most of my dates for book recommendations.
I'll categorize answers into one of the following:
- No answer -- for example, ignoring the question, answers with "I don't like to read", or answering with something that isn't a specific book, like a genre they like. 
- A book I've already read. 
- A book I haven't read, and won't end up reading before officially considering myself to be in a relationship. 
- A book I haven't read, and at least started reading before officially considering myself in a relationship. 
This market resolves when I and the person in question considers ourselves to be in a long term relationship, to:
- 0% if category 1 
- 33% if category 2 
- 66% if category 3 
- 100% if category 4 
If I ask this question multiple times, I'll strictly upgrade the answer given by the person in question. For example, if I ask for book recommendations 3 times, and I get answers in categories 1, 3, and 2, I'll resolve this market if the person gave an answer in category 3.
If I don't start any long term relationships before the resolution date, or end up in a long term relationship with someone to whom I didn't ask this question, this market resolves N/A.
I won't bet on this market.
