Input: Bacteria
There are approximately ten times as many bacterial cells in the human flora as there are human cells in the body, with the largest number of the human flora being in the gut flora, and a large number on the skin. The vast majority of the bacteria in the body are rendered harmless by the protective effects of the immune system, and some are beneficial. However, several species of bacteria are pathogenic and cause infectious diseases, including cholera, syphilis, anthrax, leprosy, and bubonic plague. The most common fatal bacterial diseases are respiratory infections, with tuberculosis alone killing about 2 million people per year, mostly in sub-Saharan Africa. In developed countries, antibiotics are used to treat bacterial infections and are also used in farming, making antibiotic resistance a growing problem. In industry, bacteria are important in sewage treatment and the breakdown of oil spills, the production of cheese and yogurt through fermentation, and the recovery of gold, palladium, copper and other metals in the mining sector, as well as in biotechnology, and the manufacture of antibiotics and other chemicals.

What is the ratio of human/bacteria cells in human flora?
Output: ten times as many bacterial cells

Input: Economy of Greece
After fourteen consecutive years of economic growth, Greece went into recession in 2008. By the end of 2009, the Greek economy faced the highest budget deficit and government debt-to-GDP ratios in the EU.

This, combined with rapidly rising debt levels (127.9% of GDP in 2009) led to a precipitous increase in borrowing costs, effectively shutting Greece out of the global financial markets and resulting in a severe economic crisis.
