Problem: Electric motor:

A major turning point in the development of DC machines took place in 1864, when Antonio Pacinotti described for the first time the ring armature with its symmetrically grouped coils closed upon themselves and connected to the bars of a commutator, the brushes of which delivered practically non-fluctuating current. The first commercially successful DC motors followed the invention by Zenobe Gramme who, in 1871, reinvented Pacinotti's design. In 1873, Gramme showed that his dynamo could be used as a motor, which he demonstrated to great effect at exhibitions in Vienna and Philadelphia by connecting two such DC motors at a distance of up to 2 km away from each other, one as a generator. (See also 1873 : l'experience decisive [Decisive Workaround] .)

Besides a motor, what didn't Gramme use the other device for?

Problem: Private CBC affiliates are not as common as they were in the past, as many such stations have been purchased either by the CBC itself or by Canwest Global or CHUM Limited, respectively becoming E! or A-Channel (later A, now CTV Two) stations. One private CBC affiliate, CHBC-TV in Kelowna, joined E! (then known as CH) on February 27, 2006. When a private CBC affiliate reaffiliates with another network, the CBC has normally added a retransmitter of its nearest O&O station to ensure that CBC service is continued. However, due to an agreement between CHBC and CFJC-TV in Kamloops, CFJC also disaffiliated from the CBC on February 27, 2006, but no retransmitters were installed in the licence area. Former private CBC affiliates CKPG-TV Prince George and CHAT-TV Medicine Hat disaffiliated on August 31, 2008 and joined E!, but the CBC announced it will not add new retransmitters to these areas. Incidentally, CFJC, CKPG and CHAT are all owned by an independent media company, Jim Pattison Group. With the closure of E! and other changes in the media landscape, several former CBC affiliates have since joined City or Global, or closed altogether.
The CBC is losing influence to what to broadcasting groups?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
On matchdays, in a tradition going back to 1962, players walk out to the theme tune to Z-Cars, named "Johnny Todd", a traditional Liverpool children's song collected in 1890 by Frank Kidson which tells the story of a sailor betrayed by his lover while away at sea, although on two separate occasions in the 1994, they ran out to different songs. In August 1994, the club played 2 Unlimited's song "Get Ready For This", and a month later, a reworking of the Creedence Clearwater Revival classic "Bad Moon Rising". Both were met with complete disapproval by Everton fans.
In what year Z-Cars have "Johnny Todd" become its theme song?
A: unanswerable

Context and question: Highlighting the potential for state and non-state actors to commit genocide in the 21st century, for example, in failed states or as non-state actors acquire weapons of mass destruction, Adrian Gallagher defined genocide as 'When a source of collective power (usually a state) intentionally uses its power base to implement a process of destruction in order to destroy a group (as defined by the perpetrator), in whole or in substantial part, dependent upon relative group size'. The definition upholds the centrality of intent, the multidimensional understanding of destroy, broadens the definition of group identity beyond that of the 1948 definition yet argues that a substantial part of a group has to be destroyed before it can be classified as genocide (dependent on relative group size).
A major part of a group has to be what in order for the centrality of intent classification to happen?
Answer: unanswerable

Question: In 2007, however, a large current account deficit and rising inflation put pressure on Estonia's currency, which was pegged to the Euro, highlighting the need for growth in export-generating industries. Estonia exports mainly machinery and equipment, wood and paper, textiles, food products, furniture, and metals and chemical products. Estonia also exports 1.562 billion kilowatt hours of electricity annually. At the same time Estonia imports machinery and equipment, chemical products, textiles, food products and transportation equipment. Estonia imports 200 million kilowatt hours of electricity annually.
Is there an answer to this question: When did a huge deficit and rising inflation place pressure on Estonia's currency?

Answer: 2007

Question: In 2002, a three judge panel on the Ninth Circuit Court of Appeals held that classroom recitation of the Pledge of Allegiance in a California public school was unconstitutional, even when students were not compelled to recite it, due to the inclusion of the phrase "under God." In reaction to the case, Elk Grove Unified School District v. Newdow, both houses of Congress passed measures reaffirming their support for the pledge, and condemning the panel's ruling. The case was appealed to the Supreme Court, where the case was ultimately overturned in June 2004, solely on procedural grounds not related to the substantive constitutional issue. Rather, a five-justice majority held that Newdow, a non-custodial parent suing on behalf of his daughter, lacked standing to sue.
Is there an answer to this question: Why was the case of Elk Grove Unified School District v. Newdow not overturned?
