If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.

[EX Q]: 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?
[EX A]: number

[EX Q]: Passage: Under a much broader definition (including people that have given up searching for employment) two different studies determined the unemployment rate to be 36.7% (2004) and 51.2% (2008), respectively. This estimate considers people in the Informal sector as employed. 72% of jobless people have been unemployed for two years or more. Labour and Social Welfare Minister Immanuel Ngatjizeko praised the 2008 study as "by far superior in scope and quality to any that has been available previously", but its methodology has also received criticism. The total number of formally employed people stood at 400,000 in 1997 and fell 330,000 in 2008, according to a government survey. The NSA 2012 study counted 396,000 formal employees. Of annually 25,000 school leavers only 8,000 gain formal employment-largely a result of a failed Education in Namibia.
Question: Were more people employed in 1997 or 2008?
[EX A]: date
