Input: Read this: The most well-known disease that affects the immune system itself is AIDS, an immunodeficiency characterized by the suppression of CD4+ ("helper") T cells, dendritic cells and macrophages by the Human Immunodeficiency Virus (HIV).
Question: What kind of disease is AIDS?

Output: an immunodeficiency

Input: Read this: Switzerland lies between latitudes 45 and 48 N, and longitudes 5 and 11 E. It contains three basic topographical areas: the Swiss Alps to the south, the Swiss Plateau or Central Plateau, and the Jura mountains on the west. The Alps are a high mountain range running across the central-south of the country, comprising about 60% of the country's total area. The majority of the Swiss population live in the Swiss Plateau. Among the high valleys of the Swiss Alps many glaciers are found, totalling an area of 1,063 square kilometres (410 sq mi). From these originate the headwaters of several major rivers, such as the Rhine, Inn, Ticino and Rhone, which flow in the four cardinal directions into the whole of Europe. The hydrographic network includes several of the largest bodies of freshwater in Central and Western Europe, among which are included Lake Geneva (also called le Lac Leman in French), Lake Constance (known as Bodensee in German) and Lake Maggiore. Switzerland has more than 1500 lakes, and contains 6% of Europe's stock of fresh water. Lakes and glaciers cover about 6% of the national territory. The largest lake is Lake Geneva, in western Switzerland shared with France. The Rhone is both the main source and outflow of Lake Geneva. Lake Constance is the second largest Swiss lake and, like the Lake Geneva, an intermediate step by the Rhine at the border to Austria and Germany. While the Rhone flows into the Mediterranean Sea at the French Camarque region and the Rhine flows into the North Sea at Rotterdam in the Netherlands, about 1000 km apart, both springs are only about 22 km apart from each other in the Swiss Alps.
Question: What is the largest lake in Switzerland?

Output: Lake Geneva

Input: Read this: Gain is a parameter which measures the degree of directivity of the antenna's radiation pattern. A high-gain antenna will radiate most of its power in a particular direction, while a low-gain antenna will radiate over a wider angle. The antenna gain, or power gain of an antenna is defined as the ratio of the intensity (power per unit surface area) radiated by the antenna in the direction of its maximum output, at an arbitrary distance, divided by the intensity radiated at the same distance by a hypothetical isotropic antenna which radiates equal power in all directions. This dimensionless ratio is usually expressed logarithmically in decibels, these units are called "decibels-isotropic" (dBi)
Question: What type of an antenna would offer the same level of power to each possible destination?

Output: isotropic

Input: Read this: The very large and ornate School Hall and School Library (by L K. Hall) were erected in 1906-8 across the road from Upper School as the school's memorial to the Etonians who had died in the Boer War. Many tablets in the cloisters and chapel commemorate the large number of dead Etonians of the Great War. A bomb destroyed part of Upper School in World War Two and blew out many windows in the Chapel. The college commissioned replacements by Evie Hone (194952) and by John Piper and Patrick Reyntiens (1959 onwards).
Question: To whom were School Hall and School Library erected in memoriam of?

Output:
Etonians who had died in the Boer War
