Problem: Kievan Rus%27:

The Crusades brought a shift in European trade routes that accelerated the decline of Kievan Rus'. In 1204 the forces of the Fourth Crusade sacked Constantinople, making the Dnieper trade route marginal. At the same time the Teutonic Knights (of the Northern Crusades) were conquering the Baltic region and threatening the Lands of Novgorod. Concurrently with it the Ruthenian Federation of Kievan Rus' started to disintegrate into smaller principalities as the Rurik dynasty grew. The local Orthodox Christianity of Kievan Rus', while struggling to establish itself in the predominantly pagan state and losing its main base in Constantinople was on the brink of extinction. Some of the main regional centres that developed later were Novgorod, Chernigov, Galich, Kiev, Ryazan, Vladimir-upon-Klyazma, Vladimir of Volyn and Polotsk.

What year did the Kievan Rus go into decline?

Problem: In some cultures, insects, especially deep-fried cicadas, are considered to be delicacies, while in other places they form part of the normal diet. Insects have a high protein content for their mass, and some authors suggest their potential as a major source of protein in human nutrition.:10–13 In most first-world countries, however, entomophagy (the eating of insects), is taboo. Since it is impossible to entirely eliminate pest insects from the human food chain, insects are inadvertently present in many foods, especially grains. Food safety laws in many countries do not prohibit insect parts in food, but rather limit their quantity. According to cultural materialist anthropologist Marvin Harris, the eating of insects is taboo in cultures that have other protein sources such as fish or livestock.
Insects have what kind of protein content?

Answer: high


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Unlike other new communist states in east-central Europe, Yugoslavia liberated itself from Axis domination with limited direct support from the Red Army. Tito's leading role in liberating Yugoslavia not only greatly strengthened his position in his party and among the Yugoslav people, but also caused him to be more insistent that Yugoslavia had more room to follow its own interests than other Bloc leaders who had more reasons (and pressures) to recognize Soviet efforts in helping them liberate their own countries from Axis control. Although Tito was formally an ally of Stalin after World War II, the Soviets had set up a spy ring in the Yugoslav party as early as 1945, giving way to an uneasy alliance.[citation needed]
Who had a leading role in liberating Yugoslavia?
A: Tito


Context and question: Apple's application to the United States Patent and Trademark Office for a patent on "rotational user inputs", as used on the iPod interface, received a third "non-final rejection" (NFR) in August 2005.

On May 15, 2006, Creative filed another suit against Apple with the United States District Court for the Northern District of California. Creative also asked the United States International Trade Commission to investigate whether Apple was breaching U.S. trade laws by importing iPods into the United States.
Which competitor sued Apple over rights to part of the software user interface?
Answer: Creative Technology


Question: The Arians no longer presented an unbroken front to their orthodox opponents. The Emperor Constantius, who had been the cause of so much trouble, died 4 November, 361 and was succeeded by Julian. The proclamation of the new prince's accession was the signal for a pagan outbreak against the still dominant Arian faction in Alexandria. George, the usurping Bishop, was flung into prison and murdered. An obscure presbyter of the name of Pistus was immediately chosen by the Arians to succeed him, when fresh news arrived that filled the orthodox party with hope. An edict had been put forth by Julian permitting the exiled bishops of the "Galileans" to return to their "towns and provinces". Athanasius received a summons from his own flock, and he accordingly re-entered his episcopal capitol on 22 February, 362.
Is there an answer to this question: Who succeeded Emperor Constantius?

Answer: Julian


QUES: Valencia stands on the banks of the Turia River, located on the eastern coast of the Iberian Peninsula and the western part of the Mediterranean Sea, fronting the Gulf of Valencia. At its founding by the Romans, it stood on a river island in the Turia, 6.4 km (4 mi) from the sea. The Albufera, a freshwater lagoon and estuary about 11 km (7 mi) south of the city, is one of the largest lakes in Spain. The City Council bought the lake from the Crown of Spain for 1,072,980 pesetas in 1911, and today it forms the main portion of the Parc Natural de l'Albufera (Albufera Nature Reserve), with a surface area of 21,120 hectares (52,200 acres). In 1986, because of its cultural, historical, and ecological value, the Generalitat Valenciana declared it a natural park.
