Problem: Guinea-Bissau:

The country was controlled by a revolutionary council until 1984. The first multi-party elections were held in 1994. An army uprising in May 1998 led to the Guinea-Bissau Civil War and the president's ousting in June 1999. Elections were held again in 2000, and Kumba Ialá was elected president.

Who controlled the country prior to 1984?
---
A: a revolutionary council


Problem: In 1939 the Regierungsbezirk Zichenau was annexed by Germany and incorporated into East Prussia. Parts of it were transferred to other regions, e.g. Suwałki to Regierungsbezirk Gumbinnen and Soldau to Regierungsbezirk Allenstein. Despite Nazi propaganda presenting all of the regions annexed as possessing significant German populations that wanted reunification with Germany, the Reich's statistics of late 1939 show that only 31,000 out of 994,092 people in this territory were ethnic Germans.[citation needed]
What ethnicity were most people in East Prussia in late 1939?

Answer: unanswerable


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Beginning in the late 1910s and early 1920s, Whitehead gradually turned his attention from mathematics to philosophy of science, and finally to metaphysics. He developed a comprehensive metaphysical system which radically departed from most of western philosophy. Whitehead argued that reality consists of processes rather than material objects, and that processes are best defined by their relations with other processes, thus rejecting the theory that reality is fundamentally constructed by bits of matter that exist independently of one another. Today Whitehead's philosophical works – particularly Process and Reality – are regarded as the foundational texts of process philosophy.
What did Whitehead first study?
A: mathematics


Context and question: Mutations or deletions of clock gene in mice have demonstrated the importance of body clocks to ensure the proper timing of cellular/metabolic events; clock-mutant mice are hyperphagic and obese, and have altered glucose metabolism. In mice, deletion of the Rev-ErbA alpha clock gene facilitates diet-induced obesity and changes the balance between glucose and lipid utilization predisposing to diabetes. However, it is not clear whether there is a strong association between clock gene polymorphisms in humans and the susceptibility to develop the metabolic syndrome.
What is the body clock gene in animals necessary to ensure?
Answer: cellular/metabolic events


Question: Economic conditions have started to improve considerably, after a period of stagnation, due to the adoption of more liberal economic policies by the government as well as increased revenues from tourism and a booming stock market. In its annual report, the International Monetary Fund (IMF) has rated Egypt as one of the top countries in the world undertaking economic reforms. Some major economic reforms undertaken by the government since 2003 include a dramatic slashing of customs and tariffs. A new taxation law implemented in 2005 decreased corporate taxes from 40% to the current 20%, resulting in a stated 100% increase in tax revenue by the year 2006.
Is there an answer to this question: What was change made to corporate taxes in 2005?

Answer: decreased corporate taxes from 40% to the current 20%


Problem: Infection:

Evidence of infection in fossil remains is a subject of interest for paleopathologists, scientists who study occurrences of injuries and illness in extinct life forms. Signs of infection have been discovered in the bones of carnivorous dinosaurs. When present, however, these infections seem to tend to be confined to only small regions of the body. A skull attributed to the early carnivorous dinosaur Herrerasaurus ischigualastensis exhibits pit-like wounds surrounded by swollen and porous bone. The unusual texture of the bone around the wounds suggests they were afflicted by a short-lived, non-lethal infection. Scientists who studied the skull speculated that the bite marks were received in a fight with another Herrerasaurus. Other carnivorous dinosaurs with documented evidence of infection include Acrocanthosaurus, Allosaurus, Tyrannosaurus and a tyrannosaur from the Kirtland Formation. The infections from both tyrannosaurs were received by being bitten during a fight, like the Herrerasaurus specimen.

What has been discovered in the blood of carnivorous dinosaurs?

A:
unanswerable
