Personally, I do not like the idea of using CR JJ in Chinese. I always think that every word in a CR question is important. The translation itself might very likely distort the meaning. You guys already have hundreds of question...
I agree with Kathy. If the wood was put into storage for a while before the house was built with it, it is very likely that some other houses might have been built during that period with wood less old. For example, if I build a house tolday with stored wood from 200 years ago, it does not mean that my house is older than houses built 50 years ago with wood of the same time. Right?
