Problem: In June 1854, the Allied expeditionary force landed at Varna, a city on the Black Sea's western coast (now in Bulgaria). They made little advance from their base there.:175176 In July 1854, the Turks under Omar Pasha crossed the Danube into Wallachia and on 7 July 1854, engaged the Russians in the city of Giurgiu and conquered it. The capture of Giurgiu by the Turks immediately threatened Bucharest in Wallachia with capture by the same Turk army. On 26 July 1854, Tsar Nicholas I ordered the withdrawal of Russian troops from the Principalities. Also, in late July 1854, following up on the Russian retreat, the French staged an expedition against the Russian forces still in Dobruja, but this was a failure.:188190
The city of Varna is located on what coast of the Black Sea?
The answer is the following: western coast

Problem: It is often said that Russia was militarily weak, technologically backward, and administratively incompetent. Despite its grand ambitions toward the south, it had not built its railroad network in that direction, and communications were poor. The bureaucracy was riddled with graft, corruption and inefficiency and was unprepared for war. Its navy was weak and technologically backward; its army, although very large, was good only for parades, suffered from colonels who pocketed their men's pay, poor morale, and was out of touch with the latest technology developed by Britain and France. By the war's end, everyone realized the profound weaknesses of the Russian military, and the Russian leadership was determined to reform it.
What did Russian colonels due to the men who served under them?
The answer is the following: pocketed their men's pay

Problem: The multiple churches that form the Anglican Communion and the Continuing Anglican movement have different views on Marian doctrines and venerative practices given that there is no single church with universal authority within the Communion and that the mother church (the Church of England) understands itself to be both "catholic" and "Reformed". Thus unlike the Protestant churches at large, the Anglican Communion (which includes the Episcopal Church in the United States) includes segments which still retain some veneration of Mary.
Which church in the United States is associated with the Angican Communion?
The answer is the following: the Episcopal Church

Problem: Carnivore and herbivore diets are contrasting, with basic nitrogen and carbon proportions vary for their particular foods. "The nitrogen content of plant tissues averages about 2%, while in fungi, animals, and bacteria it averages about 5% to 10%." Many herbivores rely on bacterial fermentation to create digestible nutrients from indigestible plant cellulose, while obligate carnivores must eat animal meats to obtain certain vitamins or nutrients their bodies cannot otherwise synthesize. All animals' diets must provide sufficient amounts of the basic building blocks they need, up to the point where their particular biology can synthesize the rest. Animal tissue contains chemical compounds, such as water, carbohydrates (sugar, starch, and fiber), amino acids (in proteins), fatty acids (in lipids), and nucleic acids (DNA and RNA). These compounds in turn consist of elements such as carbon, hydrogen, oxygen, nitrogen, phosphorus, calcium, iron, zinc, magnesium, manganese, and so on. All of these chemical compounds and elements occur in various forms and combinations (e.g. hormones, vitamins, phospholipids, hydroxyapatite).
What percentage of nitrogen content is generally found in fungi?
The answer is the following:
5% to 10%
