Problem: Gramophone record:

Delicate sounds and fine overtones were mostly lost, because it took a lot of sound energy to vibrate the recording horn diaphragm and cutting mechanism. There were acoustic limitations due to mechanical resonances in both the recording and playback system. Some pictures of acoustic recording sessions show horns wrapped with tape to help mute these resonances. Even an acoustic recording played back electrically on modern equipment sounds like it was recorded through a horn, notwithstanding a reduction in distortion because of the modern playback. Toward the end of the acoustic era, there were many fine examples of recordings made with horns.

What was the quality of sound recordings made with horns at the end of the acoustic era?
---
A: many fine examples


Problem: Damage to a German steel facility occurred during a DST transition in 1993, when a computer timing system linked to a radio time synchronization signal allowed molten steel to cool for one hour less than the required duration, resulting in spattering of molten steel when it was poured. Medical devices may generate adverse events that could harm patients, without being obvious to clinicians responsible for care. These problems are compounded when the DST rules themselves change; software developers must test and perhaps modify many programs, and users must install updates and restart applications. Consumers must update devices such as programmable thermostats with the correct DST rules, or manually adjust the devices' clocks. A common strategy to resolve these problems in computer systems is to express time using the Coordinated Universal Time (UTC) rather than the local time zone. For example, Unix-based computer systems use the UTC-based Unix time internally.
What type of computer systems use an internal clock based on UTC time?

Answer: Unix-based


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
When an inductive circuit is opened, the current through the inductance collapses quickly, creating a large voltage across the open circuit of the switch or relay. If the inductance is large enough, the energy will generate a spark, causing the contact points to oxidize, deteriorate, or sometimes weld together, or destroying a solid-state switch. A snubber capacitor across the newly opened circuit creates a path for this impulse to bypass the contact points, thereby preserving their life; these were commonly found in contact breaker ignition systems, for instance. Similarly, in smaller scale circuits, the spark may not be enough to damage the switch but will still radiate undesirable radio frequency interference (RFI), which a filter capacitor absorbs. Snubber capacitors are usually employed with a low-value resistor in series, to dissipate energy and minimize RFI. Such resistor-capacitor combinations are available in a single package.
What type of capacitor absorbs radio frequency interference?
A: a filter capacitor


Context and question: Devise Minority Party Strategies. The minority leader, in consultation with other party colleagues, has a range of strategic options that he or she can employ to advance minority party objectives. The options selected depend on a wide range of circumstances, such as the visibility or significance of the issue and the degree of cohesion within the majority party. For instance, a majority party riven by internal dissension, as occurred during the early 1900s when Progressive and "regular" Republicans were at loggerheads, may provide the minority leader with greater opportunities to achieve his or her priorities than if the majority party exhibited high degrees of party cohesion. Among the variable strategies available to the minority party, which can vary from bill to bill and be used in combination or at different stages of the lawmaking process, are the following:
What did majority parties use to advance bills in the 1900's?
Answer: unanswerable


Question: In 2002, IBM acquired PwC consulting. In 2003 it initiated a project to redefine company values. Using its Jam technology, it hosted a three-day Internet-based online discussion of key business issues with 50,000 employees. Results were data mined with sophisticated text analysis software (eClassifier) for common themes. Three emerged, expressed as: "Dedication to every client's success", "Innovation that matters—for our company and for the world", and "Trust and personal responsibility in all relationships". Another three-day Jam took place in 2004, with 52,000 employees discussing ways to implement company values in practice.
Is there an answer to this question: How many employees took part in the subsequent online discussion in 2004?

Answer: 52,000 employees


QUES: A struggle for succession in the mid-twelfth century gave the Fujiwara an opportunity to regain their former power. Fujiwara no Yorinaga sided with the retired emperor in a violent battle in 1156 against the heir apparent, who was supported by the Taira and Minamoto (Hōgen Rebellion). In the end, the Fujiwara were destroyed, the old system of government supplanted, and the insei system left powerless as bushi took control of court affairs, marking a turning point in Japanese history. In 1159, the Taira and Minamoto clashed (Heiji Rebellion), and a twenty-year period of Taira ascendancy began.

What struggle occured in the 1200's?
What is the answer?
