In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Input: Consider Input: what type of land formation was mentioned last?, Context: The city grew out towards the west of the boundaries of the peninsula formed by the River Aare. The Zytglogge tower marked the western boundary of the city from 1191 until 1256, when the Kafigturm took over this role until 1345. It was, in turn, succeeded by the Christoffelturm (formerly located close to the site of the modern-day railway station) until 1622. During the time of the Thirty Years' War, two new fortifications the so-called big and small Schanze (entrenchment) were built to protect the whole area of the peninsula.

Output: peninsula

Input: Consider Input: How much can fixing water contamination improve child mortality rates overall?, Context: Given that water contamination is a major means of transmitting diarrheal disease, efforts to provide clean water supply and improved sanitation have the potential to dramatically cut the rate of disease incidence. In fact, it has been proposed that we might expect an 88% reduction in child mortality resulting from diarrheal disease as a result of improved water sanitation and hygiene. Similarly, a meta-analysis of numerous studies on improving water supply and sanitation shows a 2227% reduction in disease incidence, and a 2130% reduction in mortality rate associated with diarrheal disease.

Output: 88%

Input: Consider Input: What does the N in "NICPB" stand for?, Context: The Estonian Academy of Sciences is the national academy of science. The strongest public non-profit research institute that carries out fundamental and applied research is the National Institute of Chemical Physics and Biophysics (NICPB; Estonian KBFI). The first computer centres were established in the late 1950s in Tartu and Tallinn. Estonian specialists contributed in the development of software engineering standards for ministries of the Soviet Union during the 1980s. As of 2011[update], Estonia spends around 2.38% of its GDP on Research and Development, compared to an EU average of around 2.0%.
Output: National
