Input: Germans
The work of David Hilbert and Max Planck was crucial to the foundation of modern physics, which Werner Heisenberg and Erwin Schrödinger developed further. They were preceded by such key physicists as Hermann von Helmholtz, Joseph von Fraunhofer, and Gabriel Daniel Fahrenheit, among others. Wilhelm Conrad Röntgen discovered X-rays, an accomplishment that made him the first winner of the Nobel Prize in Physics in 1901. The Walhalla temple for "laudable and distinguished Germans", features a number of scientists, and is located east of Regensburg, in Bavaria.

Who won the first Nobel Prize in Physics?
Output: Wilhelm Conrad Röntgen

Input: Infection
The isolation of enzymes from infected tissue can also provide the basis of a biochemical diagnosis of an infectious disease. For example, humans can make neither RNA replicases nor reverse transcriptase, and the presence of these enzymes are characteristic of specific types of viral infections. The ability of the viral protein hemagglutinin to bind red blood cells together into a detectable matrix may also be characterized as a biochemical test for viral infection, although strictly speaking hemagglutinin is not an enzyme and has no metabolic function.

What does the protein hemagglutinin bind together?
Output: red blood cells

Input: Franco-Prussian War
The creation of a unified German Empire ended the balance of power that had been created with the Congress of Vienna after the end of the Napoleonic Wars. Germany had established itself as the main power in continental Europe with the most powerful and professional army in the world.[citation needed] Although Great Britain remained the dominant world power, British involvement in European affairs during the late 19th century was very limited, allowing Germany to exercise great influence over the European mainland.[citation needed] Besides, the Crown Prince's marriage with the daughter of Queen Victoria was only the most prominent of several German–British relationships.

A unified German Empire ended the balance of power in which congress?
Output: Congress of Vienna

Input: Heian period
The Fujiwara rulers failed to maintain adequate police forces, which left robbers free to prey on travelers. This is implicitly illustrated in novels by the terror that night travel inspired in the main characters. The shōen system enabled the accumulation of wealth by an aristocratic elite; the economic surplus can be linked to the cultural developments of the Heian period and the "pursuit of arts". The major Buddhist temples in Heian-kyō and Nara also made use of the shōen. The establishment of branches rurally and integration of some Shinto shrines within these temple networks reflects a greater "organizational dynamism".

Why were travelers often robbed under Fujiwara rule?
Output:
The Fujiwara rulers failed to maintain adequate police forces
