Definition: 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.
Input: Passage: In 2010, 24.9 percent of households reported having children under the age of 18 living with them, 28.3 percent were married couples living together and 22.5 percent had a female householder with no husband present, 6.0 percent had a male householder with no wife present, and 43.2 percent were non-families. The city reported 34.1 percent of all households were made up of individuals while 10.5 percent had someone living alone who was 65 years of age or older. The average household size was 2.45 and the average family size was 3.20. In 2013, the percentage of women who gave birth in the previous 12 months who were unmarried was 56 percent. Of Philadelphias adults, 31 percent were married or lived as a couple, 55 percent were not married, 11 percent were divorced or separated, and 3 percent were widowed.

Which group for households is smaller: average family size or average household size?
