Problem: Please answer a question about the following article about MP3:
The use of lossy compression is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners. An MP3 file that is created using the setting of 128 kbit/s will result in a file that is about 1/11 the size of the CD file created from the original audio source (44,100 samples per second × 16 bits per sample × 2 channels = 1,411,200 bit/s; MP3 compressed at 128 kbit/s: 128,000 bit/s [1 k = 1,000, not 1024, because it is a bit rate]. Ratio: 1,411,200/128,000 = 11.025). An MP3 file can also be constructed at higher or lower bit rates, with higher or lower resulting quality.
How many total bit/s would a CD have?
A: 1,411,200
Problem: Please answer a question about the following article about Genocide:
In the same judgement the ECHR reviewed the judgements of several international and municipal courts judgements. It noted that International Criminal Tribunal for the Former Yugoslavia and the International Court of Justice had agreed with the narrow interpretation, that biological-physical destruction was necessary for an act to qualify as genocide. The ECHR also noted that at the time of its judgement, apart from courts in Germany which had taken a broad view, that there had been few cases of genocide under other Convention States municipal laws and that "There are no reported cases in which the courts of these States have defined the type of group destruction the perpetrator must have intended in order to be found guilty of genocide".
Two bodies of the United Nations agreed with what restricted provision in defining genocide?
A: that biological-physical destruction was necessary
Problem: Please answer a question about the following article about Pharmaceutical industry:
In the United States, new pharmaceutical products must be approved by the Food and Drug Administration (FDA) as being both safe and effective. This process generally involves submission of an Investigational New Drug filing with sufficient pre-clinical data to support proceeding with human trials. Following IND approval, three phases of progressively larger human clinical trials may be conducted. Phase I generally studies toxicity using healthy volunteers. Phase II can include pharmacokinetics and dosing in patients, and Phase III is a very large study of efficacy in the intended patient population. Following the successful completion of phase III testing, a New Drug Application is submitted to the FDA. The FDA review the data and if the product is seen as having a positive benefit-risk assessment, approval to market the product in the US is granted.
How many phases of human trials may be done after IND approval?
A: three
Problem: Please answer a question about the following article about Gramophone record:
Electric recording which developed during the time that early radio was becoming popular (1925) benefited from the microphones and amplifiers used in radio studios. The early electric recordings were reminiscent tonally of acoustic recordings, except there was more recorded bass and treble as well as delicate sounds and overtones cut on the records. This was in spite of some carbon microphones used, which had resonances that colored the recorded tone. The double button carbon microphone with stretched diaphragm was a marked improvement. Alternatively, the Wente style condenser microphone used with the Western Electric licensed recording method had a brilliant midrange and was prone to overloading from sibilants in speech, but generally it gave more accurate reproduction than carbon microphones.
What was a benefit of early radio recordings?
A:
microphones and amplifiers
