Question: Passage: Since the 1980s, US farm subsidies for rice, along with copyright and patent issues, have constituted the "major problems in U.S.-Thai trade ties". The rice subsidy was one of the primary obstacles to the negotiation of a bilateral FTA. Approximately two-thirds of Thailand's population are rice farmers, and the U.S. subsidy "severely strains U.S.-Thai relations as Bangkok finds itself unable to explain the income lost to its 35 million rice farmers". USDA-funded research to produce variants of Jasmine rice capable of growing in the US are viewed as biopiracy by many Thai rice farmers. In 2005, Thai rice farmers gathered outside the US embassy to chant a "traditional ritual to bring misfortune to enemies". Farmer protests also occurred outside the US embassy during the 2001 WTO ministerial meeting in Doha. Thai officials "sharply criticized" the Farm Security and Rural Investment Act of 2002, and retaliated by joining two WTO dispute resolution cases against the US: one against anti-dumping subsidy offsets, and the Shrimp-Turtle Case. According to Oxfam, the US spends US$1.3 billion on rice subsidies annually for a crop that costs US$1.8 billion to grow, allowing the US to become the second largest global rice exporter and dump rice at 34 percent below the cost of production. Following the election of Obama and the 2008 global financial crisis, there are Thai fears of renewed US protectionism.
Question: How many dollars less is the US paying for rice than it costs to grow?

Answer: number

Question: Passage: Antananarivo has been the largest city on the island since at least the late 18th century, when its population was estimated at 15,000. By 1810, the population had grown to 80,000 before declining dramatically between 1829 and 1842 during the reigns of Radama I and especially Ranavalona I. Because of a combination of war, forced labor, disease and harsh measures of justice, the population of Imerina fell from 750,000 to 130,000 during this period. In the final years of the Kingdom of Imerina, the population had recovered to between 50,000 and 75,000; most of the population were slaves who were largely captured in provincial military campaigns. In 1950, Antananarivos population was around 175,000. By the late 1990s the population of the metropolitan area had reached 1.4 million, and while the city itself now has a population (2013) of about 1,300,000 with suburbs lying outside the city limits it had grown to almost 2.1 million in 2013. The metropolitan area is thus home to 10 percent of the islands residents. Rural migration to the capital propels this growth; the citys population exceeds that of the other five provincial capitals combined.
Question: How many percent of the island's population lives outside the metropolitan area of Antananarivo?

Answer: number
