Problem: Please answer a question about the following article about Data compression:
Other types of lossy compressors, such as the linear predictive coding (LPC) used with speech, are source-based coders. These coders use a model of the sound's generator (such as the human vocal tract with LPC) to whiten the audio signal (i.e., flatten its spectrum) before quantization. LPC may be thought of as a basic perceptual coding technique: reconstruction of an audio signal using a linear predictor shapes the coder's quantization noise into the spectrum of the target signal, partially masking it.
What is thought of as a basic perceptual coding technique?
A: linear predictive coding
Problem: Please answer a question about the following article about Szlachta:
Poles of the 17th century assumed that "szlachta" came from the German "schlachten" ("to slaughter" or "to butcher"); also suggestive is the German "Schlacht" ("battle"). Early Polish historians thought the term may have derived from the name of the legendary proto-Polish chief, Lech, mentioned in Polish and Czech writings.
What did the poles of the 17th century think the term szlachta came from?
A: German "schlachten"
Problem: Please answer a question about the following article about Presbyterianism:
Presbyterians distinguish themselves from other denominations by doctrine, institutional organization (or "church order") and worship; often using a "Book of Order" to regulate common practice and order. The origins of the Presbyterian churches are in Calvinism. Many branches of Presbyterianism are remnants of previous splits from larger groups. Some of the splits have been due to doctrinal controversy, while some have been caused by disagreement concerning the degree to which those ordained to church office should be required to agree with the Westminster Confession of Faith, which historically serves as an important confessional document second only to the Bible, yet directing particularities in the standardization and translation of the Bible in Presbyterian churches.
Which document is an important confessional document second only to the Bible?
A: Westminster Confession of Faith
Problem: Please answer a question about the following article about Insect:
Many insects are considered pests by humans. Insects commonly regarded as pests include those that are parasitic (e.g. lice, bed bugs), transmit diseases (mosquitoes, flies), damage structures (termites), or destroy agricultural goods (locusts, weevils). Many entomologists are involved in various forms of pest control, as in research for companies to produce insecticides, but increasingly rely on methods of biological pest control, or biocontrol. Biocontrol uses one organism to reduce the population density of another organism the pest and is considered a key element of integrated pest management.
What kind of insect can damage architectural structures?
A:
termites
