Problem: Nanjing:

A few days before the fall of the city, the National Government of China was relocated to the southwestern city Chungking (Chongqing) and resumed Chinese resistance. In 1940, a Japanese-collaborationist government known as the "Nanjing Regime" or "Reorganized National Government of China" led by Wang Jingwei was established in Nanjing as a rival to Chiang Kai-shek's government in Chongqing. In 1946, after the Surrender of Japan, the KMT relocated its central government back to Nanjing.

What was another name for the Nanjing Regime?

A: "Reorganized National Government of China"

Problem: Athanasius of Alexandria:

The Gospel of John and particularly the first chapter demonstrates the Divinity of Jesus. This Gospel in itself is the greatest support of Athanasius's stand. The Gospel of John's first chapter began to be said at the end of Mass, we believe as a result of Athanasius, and his life's stand, but quietly. The Last Gospel of The Mass, The Eucharist, St John[1:114], together with the prayer; "Placeat tibi", the Blessing, are all private devotions that have been gradually absorbed by the liturgical service. The beginning of John's Gospel was much used as an object of special devotion throughout the Middle Ages. Nevertheless, the practice of saying it at the altar grew; eventually Pius V made this practice universal for the Roman Rite in his edition of the Missal (1570). It became a firm custom with exceptions in using an other Gospel in use from 1920. So the Missals showed different last Gospel for certain Feast days. A Prayer Card for the St John's Gospel. Also:

Why is the Gospel of John said at the end of Catholic Mass?

Problem: Computer security:

One use of the term "computer security" refers to technology that is used to implement secure operating systems. In the 1980s the United States Department of Defense (DoD) used the "Orange Book" standards, but the current international standard ISO/IEC 15408, "Common Criteria" defines a number of progressively more stringent Evaluation Assurance Levels. Many common operating systems meet the EAL4 standard of being "Methodically Designed, Tested and Reviewed", but the formal verification required for the highest levels means that they are uncommon. An example of an EAL6 ("Semiformally Verified Design and Tested") system is Integrity-178B, which is used in the Airbus A380 and several military jets.

Which level do many common operating systems meet?
---
A: unanswerable

Problem: Race (human categorization):

From the 17th through 19th centuries, the merging of folk beliefs about group differences with scientific explanations of those differences produced what one scholar has called an "ideology of race". According to this ideology, races are primordial, natural, enduring and distinct. It was further argued that some groups may be the result of mixture between formerly distinct populations, but that careful study could distinguish the ancestral races that had combined to produce admixed groups. Subsequent influential classifications by Georges Buffon, Petrus Camper and Christoph Meiners all classified "Negros" as inferior to Europeans. In the United States the racial theories of Thomas Jefferson were influential. He saw Africans as inferior to Whites especially in regards to their intellect, and imbued with unnatural sexual appetites, but described Native Americans as equals to whites.

What did the merging of superstitious beliefs and scientific ones regarding group differences produce?
---
A:
an "ideology of race"
