Input: Read this: Inappropriate antibiotic treatment and overuse of antibiotics have contributed to the emergence of antibiotic-resistant bacteria. Self prescription of antibiotics is an example of misuse. Many antibiotics are frequently prescribed to treat symptoms or diseases that do not respond to antibiotics or that are likely to resolve without treatment. Also, incorrect or suboptimal antibiotics are prescribed for certain bacterial infections. The overuse of antibiotics, like penicillin and erythromycin, has been associated with emerging antibiotic resistance since the 1950s. Widespread usage of antibiotics in hospitals has also been associated with increases in bacterial strains and species that no longer respond to treatment with the most common antibiotics.

Input: Read this: Under the Bretton Woods system established after World War II, the value of gold was fixed to $35 per ounce, and the value of the U.S. dollar was thus anchored to the value of gold. Rising government spending in the 1960s, however, led to doubts about the ability of the United States to maintain this convertibility, gold stocks dwindled as banks and international investors began to convert dollars to gold, and as a result the value of the dollar began to decline. Facing an emerging currency crisis and the imminent danger that the United States would no longer be able to redeem dollars for gold, gold convertibility was finally terminated in 1971 by President Nixon, resulting in the "Nixon shock".
Question: When was the Bretton Woods system established?

Output: after World War II


Input: Read this: While each wrestling match is ostensibly a competition of athletics and strategy, the goal of each match from a business standpoint is to excite and entertain the audience. Although the competition is staged, dramatic emphasis can be utilized to draw out the most intense reaction from the audience. Heightened interest results in higher attendance rates, increased ticket sales, higher ratings on television broadcasts (which result in greater ad revenue), higher pay-per-view buyrates, and sales of branded merchandise and recorded video footage. All of these contribute to the profit of the promotion company.
Question: Though the contest is staged, what can garner more interest from the crowd? 

Output: dramatic emphasis


Input: Read this: For instance, a common use of a database system is to track information about users, their name, login information, various addresses and phone numbers. In the navigational approach all of this data would be placed in a single record, and unused items would simply not be placed in the database. In the relational approach, the data would be normalized into a user table, an address table and a phone number table (for instance). Records would be created in these optional tables only if the address or phone numbers were actually provided.
Question: What happens to full data fields in a navigational system?

Output:
unanswerable
