Problem: Guinea-Bissau:

Guinea-Bissau was once part of the kingdom of Gabu, as well as part of the Mali Empire. Parts of this kingdom persisted until the 18th century, while a few others were under some rule by the Portuguese Empire since the 16th century. In the 19th century, it was colonized as Portuguese Guinea. Upon independence, declared in 1973 and recognised in 1974, the name of its capital, Bissau, was added to the country's name to prevent confusion with Guinea (formerly French Guinea). Guinea-Bissau has a history of political instability since independence, and no elected president has successfully served a full five-year term.

What year was Guinea-Bissau declared independent?
---
A: 1973


Problem: The world of clothing is always changing, as new cultural influences meet technological innovations. Researchers in scientific labs have been developing prototypes for fabrics that can serve functional purposes well beyond their traditional roles, for example, clothes that can automatically adjust their temperature, repel bullets, project images, and generate electricity. Some practical advances already available to consumers are bullet-resistant garments made with kevlar and stain-resistant fabrics that are coated with chemical mixtures that reduce the absorption of liquids.
Why is clothing slow to change?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
White light can be formed by mixing differently colored lights; the most common method is to use red, green, and blue (RGB). Hence the method is called multi-color white LEDs (sometimes referred to as RGB LEDs). Because these need electronic circuits to control the blending and diffusion of different colors, and because the individual color LEDs typically have slightly different emission patterns (leading to variation of the color depending on direction) even if they are made as a single unit, these are seldom used to produce white lighting. Nonetheless, this method has many applications because of the flexibility of mixing different colors, and in principle, this mechanism also has higher quantum efficiency in producing white light.[citation needed]
 What does the non-multi-color white LED method need to produce the end result?
A: unanswerable


Context and question: Literature grew to new heights in the Qing period. Poetry continued as a mark of the cultivated gentleman, but women wrote in larger and larger numbers and poets came from all walks of life. The poetry of the Qing dynasty is a lively field of research, being studied (along with the poetry of the Ming dynasty) for its association with Chinese opera, developmental trends of Classical Chinese poetry, the transition to a greater role for vernacular language, and for poetry by women in Chinese culture. The Qing dynasty was a period of much literary collection and criticism, and many of the modern popular versions of Classical Chinese poems were transmitted through Qing dynasty anthologies, such as the Quantangshi and the Three Hundred Tang Poems. Pu Songling brought the short story form to a new level in his Strange Stories from a Chinese Studio, published in the mid-18th century, and Shen Fu demonstrated the charm of the informal memoir in Six Chapters of a Floating Life, written in the early 19th century but published only in 1877. The art of the novel reached a pinnacle in Cao Xueqin's Dream of the Red Chamber, but its combination of social commentary and psychological insight were echoed in highly skilled novels such as Wu Jingzi's The Scholars (1750) and Li Ruzhen's Flowers in the Mirror (1827).
What was the name of Shen Fu's memoir?
Answer: Six Chapters of a Floating Life


Question: One philosophical school which has historically had a close relationship with process philosophy is American pragmatism. Whitehead himself thought highly of William James and John Dewey, and acknowledged his indebtedness to them in the preface to Process and Reality. Charles Hartshorne (along with Paul Weiss) edited the collected papers of Charles Sanders Peirce, one of the founders of pragmatism. Noted neopragmatist Richard Rorty was in turn a student of Hartshorne. Today, Nicholas Rescher is one example of a philosopher who advocates both process philosophy and pragmatism.
Is there an answer to this question:  What pragmatists did Whitehead not acknowledge in the preface to "Process and Reality"?

Answer: unanswerable


Question: As of 2010, those of Hispanic or Latino ancestry ancestry accounted for 22.5% (4,223,806) of Florida's population. Out of the 22.5%, the largest groups were 6.5% (1,213,438) Cuban, 4.5% (847,550) Puerto Rican, 3.3% (629,718) Mexican, and 1.6% (300,414) Colombian. Florida's Hispanic population includes large communities of Cuban Americans in Miami and Tampa, Puerto Ricans in Orlando and Tampa, and Mexican/Central American migrant workers. The Hispanic community continues to grow more affluent and mobile. As of 2011, 57.0% of Florida's children under the age of 1 belonged to minority groups. Florida has a large and diverse Hispanic population, with Cubans and Puerto Ricans being the largest groups in the state. Nearly 80% of Cuban Americans live in Florida, especially South Florida where there is a long-standing and affluent Cuban community. Florida has the second largest Puerto Rican population after New York, as well as the fastest-growing in the nation. Puerto Ricans are more widespread throughout the state, though the heaviest concentrations are in the Orlando area of Central Florida.
Is there an answer to this question: What area is the third largest Puerto Rican population in the US?
