instruction:
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.
question:
Passage: Greece has universal health care. In a 2000 World Health Organization report, its health care system ranked 14th in overall performance of 191 countries surveyed. In a 2013 Save the Children report, Greece was ranked the 19th best country (out of 176 countries surveyed) for the state of mothers and newborn babies. In 2010, there were 138 hospitals with 31,000 beds in the country, but on 1 July 2011, the Ministry for Health and Social Solidarity (Greece) announced its plans to decrease the number to 77 hospitals with 36,035 beds, as a necessary reform to reduce expenses and further enhance healthcare standards. Greeces healthcare expenditures as a percentage of GDP were 9.6% in 2007 according to a 2011 OECD report, just above the OECD average of 9.5%. The country has the largest number of doctors-to-population ratio of any OECD country.
answer:
How many countries ranked better than Greece according to the Save the Children report?

Passage: The Texans' defense was unable to withstand the Bills' rushing offense, especially in the first half, allowing over 100 rushing yards. Nonetheless, Houston managed to keep pace throughout despite not leading all game, but gave up a go-ahead touchdown by Charles Clay on the first play off the two-minute warning, followed by Dan Carpenter's 30-yard field goal to put it away for good. The Texans lost their first game following the bye week losing to Buffalo 21-30 and dropped to 6-6 on the season. This was also Houston's first loss to the Bills since 2006.
