Problem: Solar energy:

The total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year. In 2002, this was more energy in one hour than the world used in one year. Photosynthesis captures approximately 3,000 EJ per year in biomass. The amount of solar energy reaching the surface of the planet is so vast that in one year it is about twice as much as will ever be obtained from all of the Earth's non-renewable resources of coal, oil, natural gas, and mined uranium combined,

How much energy in exajoules does photosynthesis capture each year?
---
A: 3,000

Problem: Valencia:

Valencia was founded as a Roman colony in 138 BC. The city is situated on the banks of the Turia, on the east coast of the Iberian Peninsula, fronting the Gulf of Valencia on the Mediterranean Sea. Its historic centre is one of the largest in Spain, with approximately 169 hectares; this heritage of ancient monuments, views and cultural attractions makes Valencia one of the country's most popular tourist destinations. Major monuments include Valencia Cathedral, the Torres de Serrans, the Torres de Quart, the Llotja de la Seda (declared a World Heritage Site by UNESCO in 1996), and the Ciutat de les Arts i les Ciencies (City of Arts and Sciences), an entertainment-based cultural and architectural complex designed by Santiago Calatrava and Felix Candela. The Museu de Belles Arts de Valencia houses a large collection of paintings from the 14th to the 18th centuries, including works by Velazquez, El Greco, and Goya, as well as an important series of engravings by Piranesi. The Institut Valencia d'Art Modern (Valencian Institute of Modern Art) houses both permanent collections and temporary exhibitions of contemporary art and photography.

Problem: Florida:

As a result of these initiatives northeastern Florida prospered economically in a way it never did under Spanish rule. Furthermore, the British governors were directed to call general assemblies as soon as possible in order to make laws for the Floridas and in the meantime they were, with the advice of councils, to establish courts. This would be the first introduction of much of the English-derived legal system which Florida still has today including trial by jury, habeas corpus and county-based government. Neither East Florida nor West Florida would send any representatives to Philadelphia to draft the Declaration of Independence. Florida would remain a Loyalist stronghold for the duration of the American Revolution.

What legal system was not introduced by the British in Florida?
---
A: unanswerable

Problem: Dog:

Dogs bear their litters roughly 58 to 68 days after fertilization, with an average of 63 days, although the length of gestation can vary. An average litter consists of about six puppies, though this number may vary widely based on the breed of dog. In general, toy dogs produce from one to four puppies in each litter, while much larger breeds may average as many as twelve.

What is the average number of pups in a litter?

A:
about six
