Problem: British Isles:

The islands enjoy a mild climate and varied soils, giving rise to a diverse pattern of vegetation. Animal and plant life is similar to that of the northwestern European continent. There are however, fewer numbers of species, with Ireland having even less. All native flora and fauna in Ireland is made up of species that migrated from elsewhere in Europe, and Great Britain in particular. The only window when this could have occurred was between the end of the last Ice Age (about 12,000 years ago) and when the land bridge connecting the two islands was flooded by sea (about 8,000 years ago).

Plant and animal life varies greatly from that of life in which continent?

A: unanswerable


Problem: Representatives from indigenous and rural organizations from major South American countries, including Bolivia, Ecuador, Colombia, Chile and Brazil, started a forum in support of Morales' legal process of change. The meeting condemned plans by the European "foreign power elite" to destabilize the country. The forum also expressed solidarity with the Morales and his economic and social changes in the interest of historically marginalized majorities. Furthermore, in a cathartic blow to the US-backed elite, it questioned US interference through diplomats and NGOs. The forum was suspicious of plots against Bolivia and other countries, including Cuba, Venezuela, Ecuador, Paraguay and Nicaragua.
What was the forum suspicious of?
---
Answer: plots against Bolivia and other countries

The different dialects show many sound shifts in different vowels (even shifting between diphthongs and monophthongs), and in some cases consonants also shift pronunciation. For example, an oddity of West Flemings (and to a lesser extent, East Flemings) is that, the voiced velar fricative (written as "g" in Dutch) shifts to a voiced glottal fricative (written as "h" in Dutch), while the letter "h" in West Flemish becomes mute (just like in French). As a result, when West Flemish try to talk Standard Dutch, they're often unable to pronounce the g-sound, and pronounce it similar to the h-sound. This leaves f.e. no difference between "held" (hero) and "geld" (money). Or in some cases, they are aware of the problem, and hyper-correct the "h" into a voiced velar fricative or g-sound, again leaving no difference.
West Flemings pronounce the Dutch "g" as a voiced glottal frivative, which would be represented by what letter in standard Dutch?
A: "h"


Context and question: The most common symptom of LED (and diode laser) failure is the gradual lowering of light output and loss of efficiency. Sudden failures, although rare, can also occur. Early red LEDs were notable for their short service life. With the development of high-power LEDs the devices are subjected to higher junction temperatures and higher current densities than traditional devices. This causes stress on the material and may cause early light-output degradation. To quantitatively classify useful lifetime in a standardized manner it has been suggested to use L70 or L50, which are the runtimes (typically given in thousands of hours) at which a given LED reaches 70% and 50% of initial light output, respectively.
 What is a classification used in non-LED lighting to describe how much usefulness it will receive?
Answer: unanswerable


Question: Any living organism relies on an external source of energy—radiation from the Sun in the case of green plants, chemical energy in some form in the case of animals—to be able to grow and reproduce. The daily 1500–2000 Calories (6–8 MJ) recommended for a human adult are taken as a combination of oxygen and food molecules, the latter mostly carbohydrates and fats, of which glucose (C6H12O6) and stearin (C57H110O6) are convenient examples. The food molecules are oxidised to carbon dioxide and water in the mitochondria
Is there an answer to this question: How many weekly calories are recommended for a human adult?

Answer: unanswerable

New Haven has a history of professional sports franchises dating back to the 19th century and has been the home to professional baseball, basketball, football, hockey, and soccer teams—including the New York Giants of the National Football League from 1973 to 1974, who played at the Yale Bowl. Throughout the second half of the 20th century, New Haven consistently had minor league hockey and baseball teams, which played at the New Haven Arena (built in 1926, demolished in 1972), New Haven Coliseum (1972–2002), and Yale Field (1928–present).
At what currently defunct New Haven venues did minor league hockey and baseball teams play throughout the latter half of the 20th century?
A:
New Haven Arena (built in 1926, demolished in 1972), New Haven Coliseum (1972–2002)
