Problem: Popper coined the term "critical rationalism" to describe his philosophy. Concerning the method of science, the term indicates his rejection of classical empiricism, and the classical observationalist-inductivist account of science that had grown out of it. Popper argued strongly against the latter, holding that scientific theories are abstract in nature, and can be tested only indirectly, by reference to their implications. He also held that scientific theory, and human knowledge generally, is irreducibly conjectural or hypothetical, and is generated by the creative imagination to solve problems that have arisen in specific historico-cultural settings.
Which account of scientific method did Popper's repudiate?
The answer is the following: the classical observationalist-inductivist account

Problem: In cities other than Rome, the name cardinal began to be applied to certain church men as a mark of honour. The earliest example of this occurs in a letter sent by Pope Zacharias in 747 to Pippin III (the Short), ruler of the Franks, in which Zacharias applied the title to the priests of Paris to distinguish them from country clergy. This meaning of the word spread rapidly, and from the 9th century various episcopal cities had a special class among the clergy known as cardinals. The use of the title was reserved for the cardinals of Rome in 1567 by Pius V.
In regards to the word "cardinal" being used in cities other than Rome, who sent a letter to Pippin III?
The answer is the following: Pope Zacharias

Problem: In 1972, the French physicist Francis Perrin discovered fifteen ancient and no longer active natural nuclear fission reactors in three separate ore deposits at the Oklo mine in Gabon, West Africa, collectively known as the Oklo Fossil Reactors. The ore deposit is 1.7 billion years old; then, uranium-235 constituted about 3% of the total uranium on Earth. This is high enough to permit a sustained nuclear fission chain reaction to occur, provided other supporting conditions exist. The capacity of the surrounding sediment to contain the nuclear waste products has been cited by the U.S. federal government as supporting evidence for the feasibility to store spent nuclear fuel at the Yucca Mountain nuclear waste repository.
When the Oklo mine ore deposits came into being, what percentage of uranium on Earth consisted of uranium-235?
The answer is the following: 3%

Problem: As the 1954 congressional elections approached, and it became evident that the Republicans were in danger of losing their thin majority in both houses, Eisenhower was among those blaming the Old Guard for the losses, and took up the charge to stop suspected efforts by the right wing to take control of the GOP. Eisenhower then articulated his position as a moderate, progressive Republican: "I have just one purpose ... and that is to build up a strong progressive Republican Party in this country. If the right wing wants a fight, they are going to get it ... before I end up, either this Republican Party will reflect progressivism or I won't be with them anymore."
In what year were the first federal elections after Eisenhower became president?
The answer is the following:
1954
