Problem: Royal Institute of British Architects:

The British Architectural Library, sometimes referred to as the RIBA Library, was established in 1834 upon the founding of the institute with donations from members. Now, with over four million items, it is one of the three largest architectural libraries in the world and the largest in Europe. Some items from the collections are on permanent display at the Victoria and Albert Museum (V&A) in the V&A + RIBA Architecture Gallery and included in temporary exhibitions at the RIBA and across Europe and North America. Its collections include:

When was the RIBA library founded?

A: 1834


Problem: Maternal factors also play a role in the body’s immune response. At birth, most of the immunoglobulin present is maternal IgG. Because IgM, IgD, IgE and IgA don’t cross the placenta, they are almost undetectable at birth. Some IgA is provided by breast milk. These passively-acquired antibodies can protect the newborn for up to 18 months, but their response is usually short-lived and of low affinity. These antibodies can also produce a negative response. If a child is exposed to the antibody for a particular antigen before being exposed to the antigen itself then the child will produce a dampened response. Passively acquired maternal antibodies can suppress the antibody response to active immunization. Similarly the response of T-cells to vaccination differs in children compared to adults, and vaccines that induce Th1 responses in adults do not readily elicit these same responses in neonates. Between six to nine months after birth, a child’s immune system begins to respond more strongly to glycoproteins, but there is usually no marked improvement in their response to polysaccharides until they are at least one year old. This can be the reason for distinct time frames found in vaccination schedules.
Newborns can acquire antibodies from the mother through what means?

Answer: breast milk


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
After the Great Fire of Rome in 64 AD, Emperor Nero accused the Christians as convenient scapegoats, who were later persecuted and killed. From that point on, Roman official policy towards Christianity tended towards persecution. During the various Imperial crises of the 3rd century, “contemporaries were predisposed to decode any crisis in religious terms”, regardless of their allegiance to particular practices or belief systems. Christianity drew its traditional base of support from the powerless, who seemed to have no religious stake in the well-being of the Roman State, and therefore threatened its existence. The majority of Rome’s elite continued to observe various forms of inclusive Hellenistic monism; Neoplatonism in particular accommodated the miraculous and the ascetic within a traditional Graeco-Roman cultic framework. Christians saw these ungodly practices as a primary cause of economic and political crisis.
What outcome did the accusations against the Christians produce? 
A: persecution


Context and question: In April 2016, Northwestern announced that it signed on to the Chicago Star Partnership, a City Colleges initiative. Through this partnership, Northwestern is one of 15 Illinois public and private universities that will "provide scholarships to students who graduate from Chicago Public Schools, get their associate degree from one of the city's community colleges, and then get admitted to a bachelor's degree program." The partnership was influenced by Mayor Rahm Emanuel, who encouraged local universities to increase opportunities for students in the public school district. The University of Chicago, Northeastern Illinois University, the School of the Art Institute, DePaul University and Loyola University are also part of the Star Scholars partnership.
What City College initiative did Northwestern announce signing on with in 2016?
Answer: the Chicago Star Partnership


Question: Copper has been in use at least 10,000 years, but more than 95% of all copper ever mined and smelted has been extracted since 1900, and more than half was extracted in only the last 24 years. As with many natural resources, the total amount of copper on Earth is vast (around 1014 tons just in the top kilometer of Earth's crust, or about 5 million years' worth at the current rate of extraction). However, only a tiny fraction of these reserves is economically viable, given present-day prices and technologies. Various estimates of existing copper reserves available for mining vary from 25 years to 60 years, depending on core assumptions such as the growth rate. Recycling is a major source of copper in the modern world. Because of these and other factors, the future of copper production and supply is the subject of much debate, including the concept of peak copper, analogous to peak oil.
Is there an answer to this question: What percentage of copper has been extracted since 1900?

Answer: 95%


Problem: 51st state:

There are four categories of terra nullius, land that is unclaimed by any state: the small unclaimed territory of Bir Tawil between Egypt and Sudan, Antarctica, the oceans, and celestial bodies such as the Moon or Mars. In the last three of these, international treaties (the Antarctic Treaty, the United Nations Convention on the Law of the Sea, and the Outer Space Treaty respectively) prevent colonization and potential statehood of any of these uninhabited (and, given current technology, not permanently inhabitable) territories.

Where is Bir Tawil located?
---
A:
between Egypt and Sudan
