Do take my word with a grain of salt because I'm in high school, but this seems like a good question to me. I believe C and D because the dead fish could be bias against the fishing industry. Fishing isn't always catch and kill and someone who is less knowledgeable or specifically biased against fishing/hunting wouldn't know that there is also catch and release; and the incomes in a state are very hard to average. Take the state of Colorado for example. Denver is a fairly rich city and the average income is likely to be 5 - 6 figures while the front range and many small towns south of Denver are some of the poorest towns in the country, leaving them out of the average. I could be wrong, but I'm fairly sure I'm not.
Womens were discriminated based on their gender. The perspective to womens back then is very low resulting in not being able to vote. They are viewd as "low" and should always be dominated by the male.
