Question: Read this and answer the question

In the United States, the term "treaty" has a different, more restricted legal sense than exists in international law. United States law distinguishes what it calls treaties from executive agreement, congressional-executive agreements, and sole executive agreements. All four classes are equally treaties under international law; they are distinct only from the perspective of internal American law. The distinctions are primarily concerning their method of approval. Whereas treaties require advice and consent by two-thirds of the Senators present, sole executive agreements may be executed by the President acting alone. Some treaties grant the President the authority to fill in the gaps with executive agreements, rather than additional treaties or protocols. And finally, congressional-executive agreements require majority approval by both the House and the Senate, either before or after the treaty is signed by the President.

Under US law, what primarily distinguishes treaties, executive agreements, congressional-executive agreements, and sole executive agreements?
Answer: their method of approval


Problem: Old English was not static, and its usage covered a period of 700 years, from the Anglo-Saxon settlement of Britain in the 5th century to the late 11th century, some time after the Norman invasion. While indicating that the establishment of dates is an arbitrary process, Albert Baugh dates Old English from 450 to 1150, a period of full inflections, a synthetic language. Perhaps around 85 per cent of Old English words are no longer in use, but those that survived, to be sure, are basic elements of Modern English vocabulary.
About what percentage of Old English words are not present in Modern English?
The answer is the following: 85


In addition, there are a number of dialect characters (方言字) that are not used in formal written Chinese but represent colloquial terms in non-Mandarin varieties of Chinese. One such variety is Written Cantonese, in widespread use in Hong Kong even for certain formal documents, due to the former British colonial administration's recognition of Cantonese for use for official purposes. In Taiwan, there is also an informal body of characters used to represent Hokkien Chinese. Many varieties have specific characters for words exclusive to them. For example, the vernacular character 㓾, pronounced cii11 in Hakka, means "to kill". Furthermore, Shanghainese and Sichuanese also have their own series of written text, but these are not widely used in actual texts, Mandarin being the preference for all mainland regions.
What was the preference for all mainland regions?
Mandarin


Input: Old English
Each of these four dialects was associated with an independent kingdom on the island. Of these, Northumbria south of the Tyne, and most of Mercia, were overrun by the Vikings during the 9th century. The portion of Mercia that was successfully defended, and all of Kent, were then integrated into Wessex under Alfred the Great. From that time on, the West Saxon dialect (then in the form now known as Early West Saxon) became standardised as the language of government, and as the basis for the many works of literature and religious materials produced or translated from Latin in that period.

North of what river in Northumbria was the kingdom not overrun by the Vikings?
Output: Tyne


Input: Article: In 1629, the Massachusetts Bay Colony's first governor, John Winthrop, led the signing of the Cambridge Agreement, a key founding document of the city. Puritan ethics and their focus on education influenced its early history; America's first public school was founded in Boston in 1635. Over the next 130 years, the city participated in four French and Indian Wars, until the British defeated the French and their native allies in North America. Boston was the largest town in British North America until Philadelphia grew larger in the mid 18th century.

Now answer this question: How many french and Indian wars did Boston participate in?

Output: four


Problem: Tajikistan is landlocked, and is the smallest nation in Central Asia by area. It lies mostly between latitudes 36° and 41° N (a small area is north of 41°), and longitudes 67° and 75° E (a small area is east of 75°). It is covered by mountains of the Pamir range, and more than fifty percent of the country is over 3,000 meters (9,800 ft) above sea level. The only major areas of lower land are in the north (part of the Fergana Valley), and in the southern Kofarnihon and Vakhsh river valleys, which form the Amu Darya. Dushanbe is located on the southern slopes above the Kofarnihon valley.
Where exactly is Tajikistan?
The answer is the following:
between latitudes 36° and 41° N (a small area is north of 41°), and longitudes 67° and 75° E (a small area is east of 75°)
