Problem: Saint Helena:

In 1840, a British naval station established to suppress the African slave trade was based on the island, and between 1840 and 1849 over 15,000 freed slaves, known as "Liberated Africans", were landed there.

Between 1840 and 1849 how many freed slaves landed on the island?
---
A: over 15,000


Problem: British Empire:

The changing world order that the war had brought about, in particular the growth of the United States and Japan as naval powers, and the rise of independence movements in India and Ireland, caused a major reassessment of British imperial policy. Forced to choose between alignment with the United States or Japan, Britain opted not to renew its Japanese alliance and instead signed the 1922 Washington Naval Treaty, where Britain accepted naval parity with the United States. This decision was the source of much debate in Britain during the 1930s as militaristic governments took hold in Japan and Germany helped in part by the Great Depression, for it was feared that the empire could not survive a simultaneous attack by both nations. Although the issue of the empire's security was a serious concern in Britain, at the same time the empire was vital to the British economy.

The Great Depression helped which countries' governments become more militaristic?
---
A: Japan and Germany


Problem: Digestion:

Lactase is an enzyme that breaks down the disaccharide lactose to its component parts, glucose and galactose. Glucose and galactose can be absorbed by the small intestine. Approximately 65 percent of the adult population produce only small amounts of lactase and are unable to eat unfermented milk-based foods. This is commonly known as lactose intolerance. Lactose intolerance varies widely by ethnic heritage; more than 90 percent of peoples of east Asian descent are lactose intolerant, in contrast to about 5 percent of people of northern European descent.

What are lactoses component parts?
---
A: glucose and galactose


Problem: Insect:

Insects are the only invertebrates to have developed active flight capability, and this has played an important role in their success.:186 Their muscles are able to contract multiple times for each single nerve impulse, allowing the wings to beat faster than would ordinarily be possible. Having their muscles attached to their exoskeletons is more efficient and allows more muscle connections; crustaceans also use the same method, though all spiders use hydraulic pressure to extend their legs, a system inherited from their pre-arthropod ancestors. Unlike insects, though, most aquatic crustaceans are biomineralized with calcium carbonate extracted from the water.

Insects are also known as what kind of vertebra?
---
A:
invertebrates
