Question: In 1838 with the amount of smuggled opium entering China approaching 1,400 tons a year, the Chinese imposed a death penalty for opium smuggling and sent a Special Imperial Commissioner, Lin Zexu, to curb smuggling. This resulted in the First Opium War (183942). After the war Hong Kong island was ceded to Britain under the Treaty of Nanking and the Chinese market opened to the opium traders of Britain and other nations. The Jardines and Apcar and Company dominated the trade, although P&O also tried to take a share. A Second Opium War fought by Britain and France against China lasted from 1856 until 1860 and led to the Treaty of Tientsin, which legalised the importation of opium. Legalisation stimulated domestic Chinese opium production and increased the importation of opium from Turkey and Persia. This increased competition for the Chinese market led to India reducing its opium output and diversifying its exports.

Question: With French, Belgian and Portuguese activity in the lower Congo River region undermining orderly incursion of tropical Africa, the Berlin Conference of 188485 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.
Is there an answer to this question: What army did Britain and Egypt defeat together?

Answer: Mahdist

Question: On March 15, 1915,:8 Laemmle opened the world's largest motion picture production facility, Universal City Studios, on a 230-acre (0.9-km) converted farm just over the Cahuenga Pass from Hollywood. Studio management became the third facet of Universal's operations, with the studio incorporated as a distinct subsidiary organization. Unlike other movie moguls, Laemmle opened his studio to tourists. Universal became the largest studio in Hollywood, and remained so for a decade. However, it sought an audience mostly in small towns, producing mostly inexpensive melodramas, westerns and serials.
Is there an answer to this question: What was the biggest Hollywood studio during this period?

Answer: Universal

Question: For any prime number p, there is also the multiplicative group of integers modulo p. Its elements are the integers 1 to p 1. The group operation is multiplication modulo p. That is, the usual product is divided by p and the remainder of this division is the result of modular multiplication. For example, if p = 5, there are four group elements 1, 2, 3, 4. In this group, 4 4 = 1, because the usual product 16 is equivalent to 1, which divided by 5 yields a remainder of 1. for 5 divides 16 1 = 15, denoted
