Task: Question Answering
Input (English): passage: Colocasia esculenta is thought to be native to Southern India and Southeast Asia, but is widely naturalised. It is a perennial, tropical plant primarily grown as a root vegetable for its edible starchy corm, and as a leaf vegetable. It is a food staple in African, Oceanic and Indian cultures and is believed to have been one of the earliest cultivated plants. Colocasia is thought to have originated in the Indomalaya ecozone, perhaps in East India, Nepal, and Bangladesh, and spread by cultivation eastward into Southeast Asia, East Asia and the Pacific Islands; westward to Egypt and the eastern Mediterranean Basin; and then southward and westward from there into East Africa and West Africa, where it spread to the Caribbean and Americas. It is known by many local names and often referred to as ``elephant ears'' when grown as an ornamental plant. At around 3.3 million metric tons per year, Nigeria is the largest producer of taro in the world.
 question: is taro root the same as elephant ears?
Output (English): Yes
