Problem: Armenians:

While the Armenian Apostolic Church remains the most prominent church in the Armenian community throughout the world, Armenians (especially in the diaspora) subscribe to any number of other Christian denominations. These include the Armenian Catholic Church (which follows its own liturgy but recognizes the Roman Catholic Pope), the Armenian Evangelical Church, which started as a reformation in the Mother church but later broke away, and the Armenian Brotherhood Church, which was born in the Armenian Evangelical Church, but later broke apart from it. There are other numerous Armenian churches belonging to Protestant denominations of all kinds.

Problem: Alexander Graham Bell:

At the age of 19, he wrote a report on his work and sent it to philologist Alexander Ellis, a colleague of his father (who would later be portrayed as Professor Henry Higgins in Pygmalion). Ellis immediately wrote back indicating that the experiments were similar to existing work in Germany, and also lent Bell a copy of Hermann von Helmholtz's work, The Sensations of Tone as a Physiological Basis for the Theory of Music.

What country was doing work similar to Bell's?
---
A: Germany


Problem: Sichuan:

The Yangtze River and its tributaries flows through the mountains of western Sichuan and the Sichuan Basin; thus, the province is upstream of the great cities that stand along the Yangtze River further to the east, such as Chongqing, Wuhan, Nanjing and Shanghai. One of the major tributaries of the Yangtze within the province is the Min River of central Sichuan, which joins the Yangtze at Yibin. Sichuan's 4 main rivers, as Sichuan means literally, are Jaling Jiang, Tuo Jiang, Yalong Jiang, and Jinsha Jiang.

What river flows through eastern Sichuan?
---
A: unanswerable


Problem: Printed circuit board:

Semi-additive is the most common process: The unpatterned board has a thin layer of copper already on it. A reverse mask is then applied. (Unlike a subtractive process mask, this mask exposes those parts of the substrate that will eventually become the traces.) Additional copper is then plated onto the board in the unmasked areas; copper may be plated to any desired weight. Tin-lead or other surface platings are then applied. The mask is stripped away and a brief etching step removes the now-exposed bare original copper laminate from the board, isolating the individual traces. Some single-sided boards which have plated-through holes are made in this way. General Electric made consumer radio sets in the late 1960s using additive boards.

The patterned board has a thin layer of what already on it?
