Teacher:In this task you are given a disfluent question, a proper question and a context. A disfluent question is a question that has some interruptions in it while framing and a proper question is the correct form of the question without any disfluency. Classify whether the question is answerable or not based on the given context.
Teacher: Now, understand the problem? Solve this instance: proper question: How old were the fossils found in China?
disfluent question: How old were the Vendobionta found in China no no how old were the fossil found China not the Vendobionta?
context: The early Cambrian sessile frond-like fossil Stromatoveris, from China's Chengjiang lagerstatte and dated to about 515 million years ago, is very similar to Vendobionta of the preceding Ediacaran period. De-Gan Shu, Simon Conway Morris et al. found on its branches what they considered rows of cilia, used for filter feeding. They suggested that Stromatoveris was an evolutionary aunt of ctenophores, and that ctenophores originated from sessile animals whose descendants became swimmers and changed the cilia from a feeding mechanism to a propulsion system.
