The problem: Answer a question about this article:
The Spanish Empire and other Europeans brought horses to the Americas. Some of these animals escaped and began to breed and increase their numbers in the wild. The re-introduction of the horse, extinct in the Americas for over 7500 years, had a profound impact on Native American culture in the Great Plains of North America and of Patagonia in South America. By domesticating horses, some tribes had great success: horses enabled them to expand their territories, exchange more goods with neighboring tribes, and more easily capture game, especially bison.
What enabled some tribes to expand territory, increase trade and capture more game?
****
The answer: horses


Problem: Please answer a question about the following article about Hyderabad:
Hyderabad emerged as the foremost centre of culture in India with the decline of the Mughal Empire. After the fall of Delhi in 1857, the migration of performing artists to the city particularly from the north and west of the Indian sub continent, under the patronage of the Nizam, enriched the cultural milieu. This migration resulted in a mingling of North and South Indian languages, cultures and religions, which has since led to a co-existence of Hindu and Muslim traditions, for which the city has become noted.:viii A further consequence of this north–south mix is that both Telugu and Urdu are official languages of Telangana. The mixing of religions has also resulted in many festivals being celebrated in Hyderabad such as Ganesh Chaturthi, Diwali and Bonalu of Hindu tradition and Eid ul-Fitr and Eid al-Adha by Muslims.
The festival of Diwali is a tradition of what faith?
A: Hindu


Question: Read this and answer the question

There are four categories of terra nullius, land that is unclaimed by any state: the small unclaimed territory of Bir Tawil between Egypt and Sudan, Antarctica, the oceans, and celestial bodies such as the Moon or Mars. In the last three of these, international treaties (the Antarctic Treaty, the United Nations Convention on the Law of the Sea, and the Outer Space Treaty respectively) prevent colonization and potential statehood of any of these uninhabited (and, given current technology, not permanently inhabitable) territories.

What are the four categories of terra nullius?
Answer: the small unclaimed territory of Bir Tawil between Egypt and Sudan, Antarctica, the oceans, and celestial bodies


Problem: With French, Belgian and Portuguese activity in the lower Congo River region undermining orderly incursion of tropical Africa, the Berlin Conference of 1884–85 was held to regulate the competition between the European powers in what was called the "Scramble for Africa" by defining "effective occupation" as the criterion for international recognition of territorial claims. The scramble continued into the 1890s, and caused Britain to reconsider its decision in 1885 to withdraw from Sudan. A joint force of British and Egyptian troops defeated the Mahdist Army in 1896, and rebuffed a French attempted invasion at Fashoda in 1898. Sudan was nominally made an Anglo-Egyptian Condominium, but a British colony in reality.
When did Britain withdraw from Sudan?
The answer is the following: 1885
