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: Where was a conference held in 1884 to regulate European competition for Africa?

Answer: Berlin

GE has also been implicated in the creation of toxic waste. According to EPA documents, only the United States Government, Honeywell, and Chevron Corporation are responsible for producing more Superfund toxic waste sites.

Question: Manifold vacuum can be used to drive accessories on automobiles. The best-known application is the vacuum servo, used to provide power assistance for the brakes. Obsolete applications include vacuum-driven windscreen wipers and Autovac fuel pumps. Some aircraft instruments (Attitude Indicator (AI) and the Heading Indicator (HI)) are typically vacuum-powered, as protection against loss of all (electrically powered) instruments, since early aircraft often did not have electrical systems, and since there are two readily available sources of vacuum on a moving aircraftthe engine and an external venturi. Vacuum induction melting uses electromagnetic induction within a vacuum.
Is there an answer to this question: What can electrical systems be used to drive on automobiles?

Answer: unanswerable

Question: Two annual productions are especially notable: the Waa-Mu show, and the Dolphin show. Waa-Mu is an original musical, written and produced almost entirely by students. Children's theater is represented on campus by Griffin's Tale and Purple Crayon Players. Its umbrella organizationthe Student Theatre Coalition, or StuCo, organizes nine student theatre companies, multiple performance groups and more than sixty independent productions each year.

Chicago's Lookingglass Theatre Company, for example, which began life in the Great Room in Jones Residential College, was founded in 1988 by several alumni, including David Schwimmer; in 2011, it won the Regional Tony Award.
Is there an answer to this question: Who is the Waa-Muu show primarily written and produced by?
