Nothing wrong with the last sentense since the the proportion is uniform in all limestone. But this sentense is totally different with the one we discussed. In that sentense, there should be two rates, on in france , another in US. Only by that way, one rate can be about the same to another, or , the rates are about the same.

Note that you can say either `Gilbert is really clever' or `Gilbert really is clever'. The meaning is almost the same. In both cases you are saying that Gilbert is very clever, but when you say `Gilbert really is clever', you are expressing surprise that Gilbert is clever, or trying to convince someone else that he is.
