The problem: Answer a question about this article:
Historical linguistics emerged as an independent field of study at the end of the 18th century. Sir William Jones proposed that Sanskrit, Persian, Greek, Latin, Gothic, and Celtic languages all shared a common base. After Jones, an effort to catalog all languages of the world was made throughout the 19th century and into the 20th century. Publication of Ferdinand de Saussure's Cours de linguistique generale created the development of descriptive linguistics. Descriptive linguistics, and the related structuralism movement caused linguistics to focus on how language changes over time, instead of just describing the differences between languages. Noam Chomsky further diversified linguistics with the development of generative linguistics in the 1950s. His effort is based upon a mathematical model of language that allows for the description and prediction of valid syntax. Additional specialties such as sociolinguistics, cognitive linguistics, and computational linguistics have emerged from collaboration between linguistics and other disciplines.
What did Sir William Jones do to document his work?
****
The answer: catalog all languages of the world

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. After several upward revisions, the 2009 budget deficit is now estimated at 15.7% of GDP. 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.
How many years of consecutive growth had Greece had?
****
The answer: fourteen

The problem: Answer a question about this article:
Since the late twentieth century, the number of African and Caribbean ethnic African immigrants have increased in the United States. Together with publicity about the ancestry of President Barack Obama, whose father was from Kenya, some black writers have argued that new terms are needed for recent immigrants. They suggest that the term "African-American" should refer strictly to the descendants of African slaves and free people of color who survived the slavery era in the United States. They argue that grouping together all ethnic Africans regardless of their unique ancestral circumstances would deny the lingering effects of slavery within the American slave descendant community. They say recent ethnic African immigrants need to recognize their own unique ancestral backgrounds.
What must Africans who recently immigrated do?
****
The answer:
recognize their own unique ancestral backgrounds
