Input: Article: The 1960s and 1970s saw an acceleration in the decolonisation of Africa and the Caribbean. Over 20 countries gained independence from Britain as part of a planned transition to self-government. In 1965, however, the Rhodesian Prime Minister, Ian Smith, in opposition to moves toward majority rule, declared unilateral independence from Britain while still expressing "loyalty and devotion" to Elizabeth. Although the Queen dismissed him in a formal declaration, and the international community applied sanctions against Rhodesia, his regime survived for over a decade. As Britain's ties to its former empire weakened, the British government sought entry to the European Community, a goal it achieved in 1973.

Now answer this question: When did Britain join the European Community?

Output: 1973

Input: Article: According to Eurostat, Greece's largest port by tons of goods transported in 2010 is the port of Aghioi Theodoroi, with 17.38 million tons. The Port of Thessaloniki comes second with 15.8 million tons, followed by the Port of Piraeus, with 13.2 million tons, and the port of Eleusis, with 12.37 million tons. The total number of goods transported through Greece in 2010 amounted to 124.38 million tons, a considerable drop from the 164.3 million tons transported through the country in 2007. Since then, Piraeus has grown to become the Mediterranean's third-largest port thanks to heavy investment by Chinese logistics giant COSCO. In 2013, Piraeus was declared the fastest-growing port in the world.

Now answer this question: How many million of tons went through Aghioi Theodoroi in 2010?

Output: 17.38

Input: Article: Forests cover 24 percent of Oklahoma and prairie grasslands composed of shortgrass, mixed-grass, and tallgrass prairie, harbor expansive ecosystems in the state's central and western portions, although cropland has largely replaced native grasses. Where rainfall is sparse in the western regions of the state, shortgrass prairie and shrublands are the most prominent ecosystems, though pinyon pines, red cedar (junipers), and ponderosa pines grow near rivers and creek beds in the far western reaches of the panhandle. Southwestern Oklahoma contains many rare, disjunct species including sugar maple, bigtooth maple, nolina and southern live oak.

Now answer this question: What types of trees grow near rivers in western Oklahoma?

Output:
pinyon pines, red cedar (junipers), and ponderosa pines
