hmmmm.........this needs logic the sentence below is correct means that the sentence-"the sentence above is wrong"-is correct so the sentence above is wrong now "the sentence below is correct" must be wrong i.e. the sentence-"the sentence above is wrong"- is wrong this sentence is correct I know u are confused!!!
It's called the liar's paradox. The first sentence says that the segundo sentence is true, and the segundo sentence says that the first sentence is false. So, according to the first sentence , if it were true, the segundo sentence would be true, which says that the first sentence is false, and that means that what the first sentence says is wrong i.e. the segundo sentence is not true, so that makes the first sentence true again.. and goes on and on etc. The point in this paradox is that tu can not give either of the sentences a truth value (you can not call them true, nor false), thereby questioning our common sense about everything being either true o false. (if it is not true, then it must be false, and vice-versa)
