Problem: Protestantism:

The Protestant concept of God and man allows believers to use all their God-given faculties, including the power of reason. That means that they are allowed to explore God's creation and, according to Genesis 2:15, make use of it in a responsible and sustainable way. Thus a cultural climate was created that greatly enhanced the development of the humanities and the sciences. Another consequence of the Protestant understanding of man is that the believers, in gratitude for their election and redemption in Christ, are to follow God's commandments. Industry, frugality, calling, discipline, and a strong sense of responsibility are at the heart of their moral code. In particular, Calvin rejected luxury. Therefore, craftsmen, industrialists, and other businessmen were able to reinvest the greater part of their profits in the most efficient machinery and the most modern production methods that were based on progress in the sciences and technology. As a result, productivity grew, which led to increased profits and enabled employers to pay higher wages. In this way, the economy, the sciences, and technology reinforced each other. The chance to participate in the economic success of technological inventions was a strong incentive to both inventors and investors. The Protestant work ethic was an important force behind the unplanned and uncoordinated mass action that influenced the development of capitalism and the Industrial Revolution. This idea is also known as the "Protestant ethic thesis."

What work ethic was an influence on capitalism and the Industrial Revolution?

A: Protestant


Problem: H2 is a product of some types of anaerobic metabolism and is produced by several microorganisms, usually via reactions catalyzed by iron- or nickel-containing enzymes called hydrogenases. These enzymes catalyze the reversible redox reaction between H2 and its component two protons and two electrons. Creation of hydrogen gas occurs in the transfer of reducing equivalents produced during pyruvate fermentation to water. The natural cycle of hydrogen production and consumption by organisms is called the hydrogen cycle.
What is the natural cycle of hydrogen production and consumption by organisms called?
---
Answer: hydrogen cycle


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Since the Carnation Revolution of 1974, which culminated in the end of one of Portugal's most notable phases of economic expansion (that started in the 1960s), a significant change has occurred in the nation's annual economic growth.[citation needed] After the turmoil of the 1974 revolution and the PREC period, Portugal tried to adapt to a changing modern global economy, a process that continues in 2013. Since the 1990s, Portugal's public consumption-based economic development model has been slowly changing to a system that is focused on exports, private investment and the development of the high-tech sector. Consequently, business services have overtaken more traditional industries such as textiles, clothing, footwear and cork (Portugal is the world's leading cork producer), wood products and beverages.
Since the 90's, how has Portugal's economic development model been changing?
A: changing to a system that is focused on exports, private investment and the development of the high-tech sector


Context and question: Trademark infringement occurs when one party uses a trademark that is identical or confusingly similar to a trademark owned by another party, in relation to products or services which are identical or similar to the products or services of the other party. In many countries, a trademark receives protection without registration, but registering a trademark provides legal advantages for enforcement. Infringement can be addressed by civil litigation and, in several jurisdictions, under criminal law.
What this trademark protection require in most jurisdictions?
Answer: unanswerable


Question: The light from LEDs can be modulated very quickly so they are used extensively in optical fiber and free space optics communications. This includes remote controls, such as for TVs, VCRs, and LED Computers, where infrared LEDs are often used. Opto-isolators use an LED combined with a photodiode or phototransistor to provide a signal path with electrical isolation between two circuits. This is especially useful in medical equipment where the signals from a low-voltage sensor circuit (usually battery-powered) in contact with a living organism must be electrically isolated from any possible electrical failure in a recording or monitoring device operating at potentially dangerous voltages. An optoisolator also allows information to be transferred between circuits not sharing a common ground potential.
Is there an answer to this question: Where are LEDs not often used?

Answer: unanswerable


Most clothing appears to have been made of animal skins, as indicated by finds of large numbers of bone and antler pins which are ideal for fastening leather. Wool cloth and linen might have become available during the later Neolithic, as suggested by finds of perforated stones which (depending on size) may have served as spindle whorls or loom weights. The clothing worn in the Neolithic Age might be similar to that worn by Ötzi the Iceman, although he was not Neolithic (since he belonged to the later Copper age).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What famous figure of the Copper Age wore clothes similar to the Copper age?
Ah, so..
unanswerable
