This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning). 
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.

Q: Passage: According to the Stockholm International Peace Research Institute, between 2005-2009 and 2010-2014, Russian exports of major weapons increased by 37 percent; Russia spent $66.4 billion on arms in 2015, then $69.2 billion in 2016, having taken 3rd place (after the U.S. and China).  According to the Russian Defence Ministry, share of modern weapons in the Armed Forces reached from 26 to 48 percent among different kinds of troops in December 2014. This was raised to 30.5–70.7% as of July 2015. The average was 58 per cent over the first half of 2017.

A: Did the share of modern weapons in the Armed Forces increase or decrease between 2014 and 2015?

Q: Passage: From the Act of Union on 1 January 1801, until 6 December 1922, the island of Ireland was part of the United Kingdom of Great Britain and Ireland. During the Great Famine, from 1845 to 1849, the island's population of over 8 million fell by 30%. One million Irish died of starvation and/or disease and another 1.5 million emigrated, mostly to the United States. This set the pattern of emigration for the century to come, resulting in a constant population decline up to the 1960s.

A: After the Great Famine, Ireland's population was approximately how many people?

Q: Passage: The 19th century was dominated by the Hungarian struggle for independence and modernisation. The national insurrection against the Habsburgs began in the Hungarian capital Hungarian Revolution of 1848 and was defeated one and a half years later, with the help of the Russian Empire. 1867 was the year of Austro-Hungarian Compromise of 1867 that brought about the birth of Austria-Hungary. This made Budapest the twin capital of a dual monarchy. It was this compromise which opened the second great phase of development in the history of Budapest, lasting until World War I. In 1849 the Chain Bridge (Budapest) linking Buda with Pest was opened as the first permanent bridge across the Danube and in 1873 Buda and Pest were officially merged with the third part, Óbuda (Old Buda), thus creating the new metropolis of Budapest. The dynamic Pest grew into the countrys administrative, political, economic, trade and cultural hub. Ethnic Hungarians overtook Danube Swabians in the second half of the 19th century due to mass migration from the overpopulated rural Transdanubia and Great Hungarian Plain. Between 1851 and 1910 the proportion of Hungarians increased from 35.6% to 85.9%, Hungarian became the dominant language, and German was crowded out. The proportion of Jews peaked in 1900 with 23.6%. Due to the prosperity and the large Jewish community of the city at the start of the 20th century, Budapest was often called the "Jewish Mecca" or "Judapest". In 1918, Austria-Hungary lost the war and collapsed; Hungary declared itself an independent republic (Republic of Hungary). In 1920 the Treaty of Trianon partitioned the country, and as a result, Hungary lost over two-thirds of its territory, and about two-thirds of its inhabitants, including 3.3 million out of 15 million ethnic Hungarians.

A:
How many percentage points did the proportion of Hungarians increase between 1851 and 1910?
