Input: Read this: Although the United States has no de jure official language, English is the dominant language of business, education, government, religion, media, culture, civil society, and the public sphere. Virtually all state and federal government agencies and large corporations use English as their internal working language, especially at the management level. Some states, such as New Mexico, provide bilingual legislated notices and official documents, in Spanish and English, and other commonly used languages. By 2015, there was a trend that most Americans and American residents who are of Hispanic descent speak only English in the home.
Question: What is the official language of the United States?

QUES: Generally, American civil procedure has several notable features, including extensive pretrial discovery, heavy reliance on live testimony obtained at deposition or elicited in front of a jury, and aggressive pretrial "law and motion" practice designed to result in a pretrial disposition (that is, summary judgment) or a settlement. U.S. courts pioneered the concept of the opt-out class action, by which the burden falls on class members to notify the court that they do not wish to be bound by the judgment, as opposed to opt-in class actions, where class members must join into the class. Another unique feature is the so-called American Rule under which parties generally bear their own attorneys' fees (as opposed to the English Rule of "loser pays"), though American legislators and courts have carved out numerous exceptions.
What is an opt-in class action?

ANS: class members must join into the class


In recognition of his senior position in the Allied command, on December 20, 1944, he was promoted to General of the Army, equivalent to the rank of Field Marshal in most European armies. In this and the previous high commands he held, Eisenhower showed his great talents for leadership and diplomacy. Although he had never seen action himself, he won the respect of front-line commanders. He interacted adeptly with allies such as Winston Churchill, Field Marshal Bernard Montgomery and General Charles de Gaulle. He had serious disagreements with Churchill and Montgomery over questions of strategy, but these rarely upset his relationships with them. He dealt with Soviet Marshal Zhukov, his Russian counterpart, and they became good friends.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Along with Montgomery, with whom did Eisenhower disagree on strategy?
Ah, so.. Churchill


Question: The styles that resulted fall within several categories. In the mainstream of Georgian style were both Palladian architecture— and its whimsical alternatives, Gothic and Chinoiserie, which were the English-speaking world's equivalent of European Rococo. From the mid-1760s a range of Neoclassical modes were fashionable, associated with the British architects Robert Adam, James Gibbs, Sir William Chambers, James Wyatt, George Dance the Younger, Henry Holland and Sir John Soane. John Nash was one of the most prolific architects of the late Georgian era known as The Regency style, he was responsible for designing large areas of London. Greek Revival architecture was added to the repertory, beginning around 1750, but increasing in popularity after 1800. Leading exponents were William Wilkins and Robert Smirke.
Try to answer this question if possible: Around what year was the Greek Revival added to the repertory?
Answer: around 1750


QUES: The abdomen is the largest tagma of the insect, which typically consists of 11–12 segments and is less strongly sclerotized than the head or thorax. Each segment of the abdomen is represented by a sclerotized tergum and sternum. Terga are separated from each other and from the adjacent sterna or pleura by membranes. Spiracles are located in the pleural area. Variation of this ground plan includes the fusion of terga or terga and sterna to form continuous dorsal or ventral shields or a conical tube. Some insects bear a sclerite in the pleural area called a laterotergite. Ventral sclerites are sometimes called laterosternites. During the embryonic stage of many insects and the postembryonic stage of primitive insects, 11 abdominal segments are present. In modern insects there is a tendency toward reduction in the number of the abdominal segments, but the primitive number of 11 is maintained during embryogenesis. Variation in abdominal segment number is considerable. If the Apterygota are considered to be indicative of the ground plan for pterygotes, confusion reigns: adult Protura have 12 segments, Collembola have 6. The orthopteran family Acrididae has 11 segments, and a fossil specimen of Zoraptera has a 10-segmented abdomen.
How many segments make up an insects abdomen?

ANS:
11–12 segments
