Task: Question Answering
Input (English): Passage: Ranging from about 1 millimeter (0.039 in) to 1.5 meters (4.9 ft) in size, ctenophores are the largest non-colonial animals that use cilia ('hairs') as their main method of locomotion. Most species have eight strips, called comb rows, that run the length of their bodies and bear comb-like bands of cilia, called 'ctenes,' stacked along the comb rows so that when the cilia beat, those of each comb touch the comb below. The name 'ctenophora' means 'comb-bearing', from the Greek κτείς (stem-form κτεν-) meaning 'comb' and the Greek suffix -φορος meaning 'carrying'. Question: What are cilia used for?
Output (English): method of locomotion
