Answer: The sentence that has a synonym restatement is "Werner Faymann became the prime minister, or chancellor, of Austria".
Explanation: A synonym is a word that has the same meaning or nearly the same meaning as another word. In the sentence "Werner Faymann became the prime minister, or chancellor, of Austria", "or chancellor", which has been separated from the rest of the sentence with commas, is a synonym restatement for "the prime minister". In Austria, the Chancellor is the head of the Government; therefore, it can be used as a synonym for "prime minister".
