Ex Input:
Most of the subcontinent was conquered by the Maurya Empire during the 4th and 3rd centuries BCE. From the 3rd century BC onwards Prakrit and Pali literature in the north and the Sangam literature in southern India started to flourish. Wootz steel originated in south India in the 3rd century BC and was exported to foreign countries. Various parts of India were ruled by numerous dynasties for the next 1,500 years, among which the Gupta Empire stands out. This period, witnessing a Hindu religious and intellectual resurgence, is known as the classical or "Golden Age of India". During this period, aspects of Indian civilization, administration, culture, and religion (Hinduism and Buddhism) spread to much of Asia, while kingdoms in southern India had maritime business links with the Roman Empire from around 77 CE. Indian cultural influence spread over many parts of Southeast Asia which led to the establishment of Indianized kingdoms in Southeast Asia (Greater India).

Ex Output:
What empire conquered most of the subcontinent in the 3rd and 4th centuries BC?


Ex Input:
The avian circulatory system is driven by a four-chambered, myogenic heart contained in a fibrous pericardial sac. This pericardial sac is filled with a serous fluid for lubrication. The heart itself is divided into a right and left half, each with an atrium and ventricle. The atrium and ventricles of each side are separated by atrioventricular valves which prevent back flow from one chamber to the next during contraction. Being myogenic, the heart's pace is maintained by pacemaker cells found in the sinoatrial node, located on the right atrium. The sinoatrial node uses calcium to cause a depolarizing signal transduction pathway from the atrium through right and left atrioventricular bundle which communicates contraction to the ventricles. The avian heart also consists of muscular arches that are made up of thick bundles of muscular layers. Much like a mammalian heart, the avian heart is composed of endocardial, myocardial and epicardial layers. The atrium walls tend to be thinner than the ventricle walls, due to the intense ventricular contraction used to pump oxygenated blood throughout the body. Avian hearts are generally larger than mammalian hearts when compared to body mass. This adaptation allows more blood to be pumped to meet the high metabolic need associated with flight.

Ex Output:
The avian circulatory system is driven by what?


Ex Input:
Dutch belongs to its own West Germanic sub-group, West Low Franconian, paired with its sister language Limburgish, or East Low Franconian. Closest relative is the mutual intelligible daughter language Afrikaans. Other West Germanic languages related to Dutch are German, English and the Frisian languages, and the non standardised languages Low German and Yiddish. Dutch stands out in combining a small degree of Ingvaeonic characteristics (occurring consistently in English and Frisian and reduced in intensity from 'west to east' over the continental West Germanic plane) with mostly Istvaeonic characteristics, of which some of them are also incorporated in German. Unlike German, Dutch (apart from Limburgish) has not been influenced at all by the 'south to north' movement of the High German sound shift, and had some changes of its own. The cumulation of these changes resulted over time in separate, but related standard languages with various degrees of similarities and differences between them. For a comparison between the West Germanic languages, see the sections Morphology, Grammar and Vocabulary.

What's the "cheesy" name for East Low Franconian?
