Problem: States of Germany:

Germany is a federal republic consisting of sixteen federal states (German: Bundesland, or Land).[a] Since today's Germany was formed from an earlier collection of several states, it has a federal constitution, and the constituent states retain a measure of sovereignty. With an emphasis on geographical conditions, Berlin and Hamburg are frequently called Stadtstaaten (city-states), as is the Free Hanseatic City of Bremen, which in fact includes the cities of Bremen and Bremerhaven. The remaining 13 states are called Flachenlander (literally: area states).

Problem: Green:

There is no green pigment in green eyes; like the color of blue eyes, it is an optical illusion; its appearance is caused by the combination of an amber or light brown pigmentation of the stroma, given by a low or moderate concentration of melanin, with the blue tone imparted by the Rayleigh scattering of the reflected light. Green eyes are most common in Northern and Central Europe. They can also be found in Southern Europe, West Asia, Central Asia, and South Asia. In Iceland, 89% of women and 87% of men have either blue or green eye color. A study of Icelandic and Dutch adults found green eyes to be much more prevalent in women than in men. Among European Americans, green eyes are most common among those of recent Celtic and Germanic ancestry, about 16%.

What percentage of women in South Asia have blue or green eyes?

A: unanswerable

Problem: Railway electrification system:

On tracks that London Underground share with National Rail third-rail stock (the Bakerloo and District lines both have such sections), the centre rail is connected to the running rails, allowing both types of train to operate, at a compromise voltage of 660 V. Underground trains pass from one section to the other at speed; lineside electrical connections and resistances separate the two types of supply. These routes were originally solely electrified on the four-rail system by the LNWR before National Rail trains were rewired to their standard three-rail system to simplify rolling stock use.

What joins the two types of supply?

A: unanswerable

Problem: University of Notre Dame:

Father Joseph Carrier, C.S.C. was Director of the Science Museum and the Library and Professor of Chemistry and Physics until 1874. Carrier taught that scientific research and its promise for progress were not antagonistic to the ideals of intellectual and moral culture endorsed by the Church. One of Carrier's students was Father John Augustine Zahm (18511921) who was made Professor and Co-Director of the Science Department at age 23 and by 1900 was a nationally prominent scientist and naturalist. Zahm was active in the Catholic Summer School movement, which introduced Catholic laity to contemporary intellectual issues. His book Evolution and Dogma (1896) defended certain aspects of evolutionary theory as true, and argued, moreover, that even the great Church teachers Thomas Aquinas and Augustine taught something like it. The intervention of Irish American Catholics in Rome prevented Zahm's censure by the Vatican. In 1913, Zahm and former President Theodore Roosevelt embarked on a major expedition through the Amazon.
