Problem: Although Bell was, and still is, accused of stealing the telephone from Gray, Bell used Gray's water transmitter design only after Bell's patent had been granted, and only as a proof of concept scientific experiment, to prove to his own satisfaction that intelligible "articulate speech" (Bell's words) could be electrically transmitted. After March 1876, Bell focused on improving the electromagnetic telephone and never used Gray's liquid transmitter in public demonstrations or commercial use.
Bell stopped using the liquid-based method after what month?

Problem: Straddling the intersection of Germanic and Romance Europe, Switzerland comprises four main linguistic and cultural regions: German, French, Italian and Romansh. Therefore, the Swiss, although predominantly German-speaking, do not form a nation in the sense of a common ethnicity or language; rather, Switzerland's strong sense of identity and community is founded on a common historical background, shared values such as federalism and direct democracy, and Alpine symbolism. Due to its linguistic diversity, Switzerland is known by a variety of native names: Schweiz [vats] (German);[note 5] Suisse [sis()] (French); Svizzera [zvittsera] (Italian); and Svizra [vitsr] or [vits] (Romansh).[note 6]
What do the French Swiss call Switzerland?
The answer is the following: Suisse

Problem: Anti-government protests in 1991 led to a coup, a transitional government, and a new constitution. Opposition to the corrupt and dictatorial regime of General Moussa Traore grew during the 1980s. During this time strict programs, imposed to satisfy demands of the International Monetary Fund, brought increased hardship upon the country's population, while elites close to the government supposedly lived in growing wealth.

Scattered acts of rioting and vandalism of public buildings followed, but most actions by the dissidents remained nonviolent.
What type of administration did general Mousa Traore have?
The answer is the following:
dictatorial regime
