Input: Antibiotics
The emergence of resistance of bacteria to antibiotics is a common phenomenon. Emergence of resistance often reflects evolutionary processes that take place during antibiotic therapy. The antibiotic treatment may select for bacterial strains with physiologically or genetically enhanced capacity to survive high doses of antibiotics. Under certain conditions, it may result in preferential growth of resistant bacteria, while growth of susceptible bacteria is inhibited by the drug. For example, antibacterial selection for strains having previously acquired antibacterial-resistance genes was demonstrated in 1943 by the LuriaDelbruck experiment. Antibiotics such as penicillin and erythromycin, which used to have a high efficacy against many bacterial species and strains, have become less effective, due to the increased resistance of many bacterial strains.

Which two antibiotics that have high efficacy are much less useful now?
Output: penicillin and erythromycin

Article: Greek Cypriots and Turkish Cypriots share a lot in common in their culture but also have differences. Several traditional food (such as souvla and halloumi) and beverages are similar, as well as expressions and ways of life. Hospitality and buying or offering food and drinks for guests or others are common among both. In both communities, music, dance and art are integral parts of social life and many artistic, verbal and nonverbal expressions, traditional dances such as tsifteteli, similarities in dance costumes and importance placed on social activities are shared between the communities. However, the two communities have distinct religions and religious cultures, with the Greek Cypriots traditionally being Greek Orthodox and Turkish Cypriots traditionally being Sunni Muslims, which has partly hindered cultural exchange. Greek Cypriots have influences from Greece and Christianity, while Turkish Cypriots have influences from Turkey and Islam.

Question: Which foods do Greek Cypriots and Turkish Cypriots have in common?
Ans: souvla and halloumi

Here is a question about this article: Various ecumenical movements have attempted cooperation or reorganization of the various divided Protestant denominations, according to various models of union, but divisions continue to outpace unions, as there is no overarching authority to which any of the churches owe allegiance, which can authoritatively define the faith. Most denominations share common beliefs in the major aspects of the Christian faith while differing in many secondary doctrines, although what is major and what is secondary is a matter of idiosyncratic belief.
What is the answer to this question: What beliefs do most denominations agree on?
****
So... common beliefs in the major aspects of the Christian faith

The problem: Answer a question about this article:
As of 2006, the iPod was produced by about 14,000 workers in the U.S. and 27,000 overseas. Further, the salaries attributed to this product were overwhelmingly distributed to highly skilled U.S. professionals, as opposed to lower skilled U.S. retail employees or overseas manufacturing labor. One interpretation of this result is that U.S. innovation can create more jobs overseas than domestically.
What attribute of the United States could be thought to lead more international and less domestic employment opportunities?
****
The answer: innovation

Evidence from the early technical literature concerning electrical recording suggests that it wasn't until the 19421949 period that there were serious efforts to standardize recording characteristics within an industry. Heretofore, electrical recording technology from company to company was considered a proprietary art all the way back to the 1925 Western Electric licensed method used by Columbia and Victor. For example, what Brunswick-Balke-Collender (Brunswick Corporation) did was different from the practices of Victor.
How far back did records show the art of sound recordings?
****
The answer:
1925
