Problem: MP3:

With too low a bit rate, compression artifacts (i.e., sounds that were not present in the original recording) may be audible in the reproduction. Some audio is hard to compress because of its randomness and sharp attacks. When this type of audio is compressed, artifacts such as ringing or pre-echo are usually heard. A sample of applause compressed with a relatively low bit rate provides a good example of compression artifacts.

Other than pre - echo, what is another example of what can happen when audio is compressed?
---
A: ringing


Problem: In 2006, after almost 80 years, NBC Universal sold all Walt Disney-produced Oswald cartoons, along with the rights to the character himself, back to Disney.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
After many other more or less successful attempts with relatively weak rotating and reciprocating apparatus the Prussian Moritz von Jacobi created the first real rotating electric motor in May 1834 that actually developed a remarkable mechanical output power. His motor set a world record which was improved only four years later in September 1838 by Jacobi himself. His second motor was powerful enough to drive a boat with 14 people across a wide river. It was not until 1839/40 that other developers worldwide managed to build motors of similar and later also of higher performance.
 Who created the first fake electric motor?
A: unanswerable


Context and question: Rajasthani cooking was influenced by both the war-like lifestyles of its inhabitants and the availability of ingredients in this arid region. Food that could last for several days and could be eaten without heating was preferred. The scarcity of water and fresh green vegetables have all had their effect on the cooking.

Question: Primary resistance occurs when a person becomes infected with a resistant strain of TB. A person with fully susceptible MTB may develop secondary (acquired) resistance during therapy because of inadequate treatment, not taking the prescribed regimen appropriately (lack of compliance), or using low-quality medication. Drug-resistant TB is a serious public health issue in many developing countries, as its treatment is longer and requires more expensive drugs. MDR-TB is defined as resistance to the two most effective first-line TB drugs: rifampicin and isoniazid. Extensively drug-resistant TB is also resistant to three or more of the six classes of second-line drugs. Totally drug-resistant TB is resistant to all currently used drugs. It was first observed in 2003 in Italy, but not widely reported until 2012, and has also been found in Iran and India. Bedaquiline is tentatively supported for use in multiple drug-resistant TB.
Is there an answer to this question: Cases of totally drug-resistant TB have been found in what country in addition to Italy and India?

Answer: Iran


Question: Comparative and historical linguistics offers some clues for memorising the accent position: If one compares many standard Serbo-Croatian words to e.g. cognate Russian words, the accent in the Serbo-Croatian word will be one syllable before the one in the Russian word, with the rising tone. Historically, the rising tone appeared when the place of the accent shifted to the preceding syllable (the so-called "Neoshtokavian retraction"), but the quality of this new accent was different – its melody still "gravitated" towards the original syllable. Most Shtokavian dialects (Neoshtokavian) dialects underwent this shift, but Chakavian, Kajkavian and the Old Shtokavian dialects did not.
Is there an answer to this question: What offers some clues for how dialects were different?

Answer:
unanswerable
