Here is a question about this article: More-or-less independent circadian rhythms are found in many organs and cells in the body outside the suprachiasmatic nuclei (SCN), the "master clock". These clocks, called peripheral oscillators, are found in the adrenal gland,[citation needed] oesophagus, lungs, liver, pancreas, spleen, thymus, and skin.[citation needed] Though oscillators in the skin respond to light, a systemic influence has not been proven. There is also some evidence that the olfactory bulb and prostate may experience oscillations when cultured, suggesting that these structures may also be weak oscillators.[citation needed]
What is the answer to this question: Where else beside the SCN cells are independent circadian rhythms also found?
****
So... organs and cells


The problem: Answer a question about this article:
Bird migration routes have been studied by a variety of techniques including the oldest, marking. Swans have been marked with a nick on the beak since about 1560 in England. Scientific ringing was pioneered by Hans Christian Cornelius Mortensen in 1899. Other techniques include radar and satellite tracking.
How have swans been marked?
****
The answer: a nick on the beak


Problem: Please answer a question about the following article about Race and ethnicity in the United States Census:
Race was asked differently in the Census 2000 in several other ways than previously. Most significantly, respondents were given the option of selecting one or more race categories to indicate racial identities. Data show that nearly seven million Americans identified as members of two or more races. Because of these changes, the Census 2000 data on race are not directly comparable with data from the 1990 census or earlier censuses. Use of caution is therefore recommended when interpreting changes in the racial composition of the US population over time.
What year was the last census before the Census 2000?
A: 1990


Question: Read this and answer the question

US army general Hoyt Vandenberg, the CIG's second director, created the Office of Special Operations (OSO), as well as the Office of Reports and Estimates (ORE). Initially the OSO was tasked with spying and subversion overseas with a budget of $15 million, the largesse of a small number of patrons in congress. Vandenberg's goals were much like the ones set out by his predecessor; finding out "everything about the Soviet forces in Eastern and Central Europe - their movements, their capabilities, and their intentions." This task fell to the 228 overseas personnel covering Germany, Austria, Switzerland, Poland, Czechoslovakia, and Hungary.

What was the Office of Special Operations initial budget?
Answer: $15 million


Problem: The most common symptom of LED (and diode laser) failure is the gradual lowering of light output and loss of efficiency. Sudden failures, although rare, can also occur. Early red LEDs were notable for their short service life. With the development of high-power LEDs the devices are subjected to higher junction temperatures and higher current densities than traditional devices. This causes stress on the material and may cause early light-output degradation. To quantitatively classify useful lifetime in a standardized manner it has been suggested to use L70 or L50, which are the runtimes (typically given in thousands of hours) at which a given LED reaches 70% and 50% of initial light output, respectively.
What is a classification used in LED lighting to describe how much usefulness it will receive?
The answer is the following: L70 or L50


Input: Article: The Times used contributions from significant figures in the fields of politics, science, literature, and the arts to build its reputation. For much of its early life, the profits of The Times were very large and the competition minimal, so it could pay far better than its rivals for information or writers. Beginning in 1814, the paper was printed on the new steam-driven cylinder press developed by Friedrich Koenig. In 1815, The Times had a circulation of 5,000.

Now answer this question: Who developed the new press type in 1814 for The Times?

Output:
Friedrich Koenig
