Input: Read this: A study published in the Neuropsychopharmacology journal in 2013 revealed the finding that the flavour of beer alone could provoke dopamine activity in the brain of the male participants, who wanted to drink more as a result. The 49 men in the study were subject to positron emission tomography scans, while a computer-controlled device sprayed minute amounts of beer, water and a sports drink onto their tongues. Compared with the taste of the sports drink, the taste of beer significantly increased the participants desire to drink. Test results indicated that the flavour of the beer triggered a dopamine release, even though alcohol content in the spray was insufficient for the purpose of becoming intoxicated.

Input: Read this: There are a number of proposals to redefine certain of the SI base units in terms of fundamental physical constants. This has already been done for the metre, which is defined in terms of a fixed value of the speed of light. The most urgent unit on the list for redefinition is the kilogram, whose value has been fixed for all science (since 1889) by the mass of a small cylinder of platinumiridium alloy kept in a vault just outside Paris. While nobody knows if the mass of the International Prototype Kilogram has changed since 1889 the value 1 kg of its mass expressed in kilograms is by definition unchanged and therein lies one of the problems it is known that over such a timescale the many similar PtIr alloy cylinders kept in national laboratories around the world, have changed their relative mass by several tens of parts per million, however carefully they are stored, and the more so the more they have been taken out and used as mass standards. A change of several tens of micrograms in one kilogram is equivalent to the current uncertainty in the value of the Planck constant in SI units.
Question: What is the shape of the object that establishes the base unit of the kilometer?

Output: unanswerable

Input: Read this: The most impressive and famous of Sumerian buildings are the ziggurats, large layered platforms which supported temples. Sumerian cylinder seals also depict houses built from reeds not unlike those built by the Marsh Arabs of Southern Iraq until as recently as 400 CE. The Sumerians also developed the arch, which enabled them to develop a strong type of dome. They built this by constructing and linking several arches. Sumerian temples and palaces made use of more advanced materials and techniques,[citation needed] such as buttresses, recesses, half columns, and clay nails.
Question: Sumerians also built houses from reeds not very different from ones built by inhabitants in Iraq as recently as when?

Output: 400 CE

Input: Read this: In 1978, Jim Shooter became Marvel's editor-in-chief. Although a controversial personality, Shooter cured many of the procedural ills at Marvel, including repeatedly missed deadlines. During Shooter's nine-year tenure as editor-in-chief, Chris Claremont and John Byrne's run on the Uncanny X-Men and Frank Miller's run on Daredevil became critical and commercial successes. Shooter brought Marvel into the rapidly evolving direct market, institutionalized creator royalties, starting with the Epic Comics imprint for creator-owned material in 1982; introduced company-wide crossover story arcs with Contest of Champions and Secret Wars; and in 1986 launched the ultimately unsuccessful New Universe line to commemorate the 25th anniversary of the Marvel Comics imprint. Star Comics, a children-oriented line differing from the regular Marvel titles, was briefly successful during this period.
Question: What is an example of a bad practice eliminated under Shooter's regime at Marvel?

Output:
repeatedly missed deadlines
