Problem: Department store:

Panama's first department stores such as Bazaar Francés, La Dalia and La Villa de Paris started as textile retailers at the turn of the nineteenth century. Later on in the twentieth century these eventually gave way to stores such as Felix B. Maduro, Sarah Panamá, Figali, Danté, Sears, Gran Morrison and smaller ones such as Bon Bini, Cocos, El Lider, Piccolo and Clubman among others. Of these only Felix B. Maduro (usually referred to as Felix by locals) and Danté remain strong. All the others have either folded or declined although Cocos has managed to secure a good position in the market.

What store has managed to close despite much it's competition thriving?

A: unanswerable


Problem: Another advantage, at least to some consumers, was the lack of any sort of anti-piracy technology. It was claimed that Macrovision's Copyguard protection could not be applied to LaserDisc, due to the format's design. The vertical blanking interval, where the Macrovision signal would be implemented, was also used for the internal timing on LaserDisc players, so test discs with Macrovision would not play at all. There was never a push to redesign the format despite the obvious potential for piracy due to its relatively small market share. The industry simply decided to engineer it into the DVD specification.
What protection could not be applied to LaserDiscs, making them prone to piracy?
---
Answer: Macrovision's Copyguard protection


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Hinkley Point C nuclear power station is a project to construct a 3,200 MW two reactor nuclear power station. On 18 October 2010, the British government announced that Hinkley Point – already the site of the disused Hinkley Point A and the still operational Hinkley Point B power stations – was one of the eight sites it considered suitable for future nuclear power stations. NNB Generation Company, a subsidiary of EDF, submitted an application for development consent to the Infrastructure Planning Commission on 31 October 2011. A protest group, Stop Hinkley, was formed to campaign for the closure of Hinkley Point B and oppose any expansion at the Hinkley Point site. In December 2013, the European Commission opened an investigation to assess whether the project breaks state-aid rules. On 8 October 2014 it was announced that the European Commission has approved the project, with an overwhelming majority and only four commissioners voting against the decision.
What did the European Commission review 
A: opened an investigation to assess whether the project breaks state-aid rules


Context and question: All animals have eukaryotic cells, surrounded by a characteristic extracellular matrix composed of collagen and elastic glycoproteins. This may be calcified to form structures like shells, bones, and spicules. During development, it forms a relatively flexible framework upon which cells can move about and be reorganized, making complex structures possible. In contrast, other multicellular organisms, like plants and fungi, have cells held in place by cell walls, and so develop by progressive growth. Also, unique to animal cells are the following intercellular junctions: tight junctions, gap junctions, and desmosomes.
What is the extracellular matrix surrounding eukaryotic cells made of?
Answer: collagen and elastic glycoproteins


Question: Despite this, the Austrians, under the command of General Laudon, captured Glatz (now Kłodzko, Poland) in Silesia. In the Battle of Liegnitz Frederick scored a strong victory despite being outnumbered three to one. The Russians under General Saltykov and Austrians under General Lacy briefly occupied his capital, Berlin, in October, but could not hold it for long. The end of that year saw Frederick once more victorious, defeating the able Daun in the Battle of Torgau; but he suffered very heavy casualties, and the Austrians retreated in good order.
Is there an answer to this question: Identify a success of the Austrians?

Answer: the Austrians, under the command of General Laudon, captured Glatz


QUES: Conventional ("tailhook") aircraft rely upon a landing signal officer (LSO, radio call sign paddles) to monitor the aircraft's approach, visually gauge glideslope, attitude, and airspeed, and transmit that data to the pilot. Before the angled deck emerged in the 1950s, LSOs used colored paddles to signal corrections to the pilot (hence the nickname). From the late 1950s onward, visual landing aids such as Optical Landing System have provided information on proper glide slope, but LSOs still transmit voice calls to approaching pilots by radio.

What are LSO's still being used to do?
What is the answer?
ANS:
transmit voice calls to approaching pilots by radio
