Problem: Gamal Abdel Nasser:

In 1944, Nasser married Tahia Kazem, the 22-year-old daughter of a wealthy Iranian father and an Egyptian mother, both of whom died when she was young. She was introduced to Nasser through her brother, Abdel Hamid Kazim, a merchant friend of Nasser's, in 1943. After their wedding, the couple moved into a house in Manshiyat al-Bakri, a suburb of Cairo, where they would live for the rest of their lives. Nasser's entry into the officer corps in 1937 secured him relatively well-paid employment in a society where most people lived in poverty.

What job of Nasser's offered him a comparably comfortable lifestyle?
---
A: officer corps

Problem: Uranium:

Uranium's average concentration in the Earth's crust is (depending on the reference) 2 to 4 parts per million, or about 40 times as abundant as silver. The Earth's crust from the surface to 25 km (15 mi) down is calculated to contain 1017 kg (21017 lb) of uranium while the oceans may contain 1013 kg (21013 lb). The concentration of uranium in soil ranges from 0.7 to 11 parts per million (up to 15 parts per million in farmland soil due to use of phosphate fertilizers), and its concentration in sea water is 3 parts per billion.

Why is the concentrate of uranium in farmland so high?
---
A: phosphate fertilizers

Problem: Red:

The Romans liked bright colors, and many Roman villas were decorated with vivid red murals. The pigment used for many of the murals was called vermilion, and it came from the mineral cinnabar, a common ore of mercury. It was one of the finest reds of ancient times the paintings have retained their brightness for more than twenty centuries. The source of cinnabar for the Romans was a group of mines near Almaden, southwest of Madrid, in Spain. Working in the mines was extremely dangerous, since mercury is highly toxic; the miners were slaves or prisoners, and being sent to the cinnabar mines was a virtual death sentence.

What color were Roman villas painted?

A: unanswerable

Problem: Karl Popper:

Popper played a vital role in establishing the philosophy of science as a vigorous, autonomous discipline within philosophy, through his own prolific and influential works, and also through his influence on his own contemporaries and students. Popper founded in 1946 the Department of Philosophy, Logic and Scientific Method at the London School of Economics and there lectured and influenced both Imre Lakatos and Paul Feyerabend, two of the foremost philosophers of science in the next generation of philosophy of science. (Lakatos significantly modified Popper's position,:1 and Feyerabend repudiated it entirely, but the work of both is deeply influenced by Popper and engaged with many of the problems that Popper set.)

What department did Einstein found in 1946 in London?

A:
unanswerable
