Where is/are the mistakes in these sentences? It's an exercise and there are 3 segments underlined (which I don't know how to do in here) to find the one or the ones that contains/contain a mistake : "It is said that the new government is fighting for the end of the poverty in our country. I've seen a lot of politicians to promise that, but none of them had accomplished such task." The underlined segments which I have to check if there are mistakes are: It is said, to promise that and had accomplished such a task. I guess, but I'm not quite sure that "to promise that" and "had accomplished" are wrong. I mean I would say "promise that" and "have accomplished". Can someone help me? Thank you in advance.
