Ans: the Archaic , the Classical and the Hellenistic
Ques: Passage: There are three scholarly divisions of the stages of later ancient Greek art that correspond roughly with historical periods of the same names. These are the Archaic, the Classical and the Hellenistic. The Archaic period is usually dated from 1000 BC. The Persian Wars of 480 BC to 448 BC are usually taken as the dividing line between the Archaic and the Classical periods, and the death of Alexander the Great in 323 BC is regarded as separating the Classical from the Hellenistic period. Of course, different forms of art developed at different speeds in different parts of the Greek world, and varied to a degree from artist to artist. There was a sharp transition from one period to another.

Ans: 10,000 years ago
Ques: Smilodon is an extinct genus of machairodont felid. It is one of the most famous prehistoric mammals, and the best known saber-toothed cat. Although commonly known as the saber-toothed tiger, it was not closely related to the tiger or other modern cats. Smilodon lived in the Americas during the Pleistocene epoch (2.5 mya -- 10,000 years ago). The genus was named in 1842, based on fossils from Brazil. Three species are recognized today: S. gracilis, S. fatalis, and S. populator. The two latter species were probably descended from S. gracilis, which itself probably evolved from Megantereon. The largest collection of Smilodon fossils has been obtained from the Rancho La Brea Tar Pits in Los Angeles, California.

Answer this question based on the passage: when did the saber tooth tiger go extinct?
CoT: The important part for answering this question is: Smilodon lived in the Americas during the Pleistocene epoch (2.5 mya -- 10,000 years ago).
