Input: Article: In recent years, Nanjing has been developing its economy, commerce, industry, as well as city construction. In 2013 the city's GDP was RMB 801 billion (3rd in Jiangsu), and GDP per capita(current price) was RMB 98,174(US$16041), a 11 percent increase from 2012. The average urban resident's disposable income was RMB 36,200, while the average rural resident's net income was RMB 14,513. The registered urban unemployment rate was 3.02 percent, lower than the national average (4.3 percent). Nanjing's Gross Domestic Product ranked 12th in 2013 in China, and its overall competence ranked 6th in mainland and 8th including Taiwan and Hong Kong in 2009.

Now answer this question: Was the GDP in 2013 an increase or decrease over 2012's levels?

Output: increase

Input: Article: From the years 1500 to 1850, an estimated 3.5 million captives were forcibly shipped from West/Central Africa to Brazil; the territory received the highest number of slaves of any country in the Americas. Scholars estimate that more than half of the Brazilian population is at least in part descended from these individuals. Brazil has the largest population of Afro-descendants outside of Africa. In contrast to the US, during the slavery period and after, the Portuguese colonial government and later Brazilian government did not pass formal anti-miscegenation or segregation laws. As in other Latin countries, intermarriage was prevalent during the colonial period and continued afterward. In addition, people of mixed race (pardo) often tended to marry white, and their descendants became accepted as white. As a result, some of the European descended population also has West African or Amerindian blood. According to the last census of the 20th century, in which Brazilians could choose from five color/ethnic categories with which they identified, 54% of individuals identified as white, 6.2% identified as black, and 39.5% identified as pardo (brown) a broad multi-racial category, including tri-racial persons.

Now answer this question: How many slaves were shipped from Africa to Brazil between 1500 and 1850?

Output: estimated 3.5 million

Input: Article: Filming temporarily returned to England to shoot scenes at Blenheim Palace in Oxfordshire, which stood in for a location in Rome, before moving on to the city itself for a five-week shoot across the city, with locations including the Ponte Sisto bridge and the Roman Forum. The production faced opposition from a variety of special interest groups and city authorities, who were concerned about the potential for damage to historical sites around the city, and problems with graffiti and rubbish appearing in the film. A car chase scene set along the banks of the Tiber River and through the streets of Rome featured an Aston Martin DB10 and a Jaguar C-X75. The C-X75 was originally developed as a hybrid electric vehicle with four independent electric engines powered by two jet turbines, before the project was cancelled. The version used for filming was converted to use a conventional internal combustion engine, to minimise the potential for disruption from mechanical problems with the complex hybrid system. The C-X75s used for filming were developed by the engineering division of Formula One racing team Williams, who built the original C-X75 prototype for Jaguar.

Now answer this question: What two cars were featured in a chase scene along the banks of the Tiber River?

Output:
Aston Martin DB10 and a Jaguar C-X75
