Given the task definition and input, reply with output. 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.

Passage: According to the 2009 American Community Survey, the average household size was 2.11, and the average family size was 3.21. Approximately 59.4% of the population over the age of 25 have a bachelors degree or higher. Approximately 27.0% of the population is foreign-born, and 61.7% of the population over the age of 5 speak only English at home. People of Irish American ancestry make up 7.8% of the population, while Italian Americans make up 6.8% of the population. German Americans and Russian Americans make up 7.2% and 6.2% of the population respectively.

How many in percent from the survey weren't German American?
