The cathedral has a heliometer (solar "observatory") of 1690, one of a number built in Italy in the 17th and 18th centuries. The device itself is quite simple: a tiny hole in one of the minor domes acts as pinhole camera, projecting an image of the sun onto the floor at solar noon (12:00 in winter, 13:00 in summer). There is a bronze line, la Meridiana on the floor, running precisely N/S. The ends of the line mark the positions as at the summer and winter solstices; signs of the zodiac show the various other dates throughout the year.

What name is given to the bronze line on the floor of a heliometer?
Answer: la Meridiana

Problem: Worldwide consumption of paper has risen by 400% in the past 40 years leading to increase in deforestation, with 35% of harvested trees being used for paper manufacture. Most paper companies also plant trees to help regrow forests. Logging of old growth forests accounts for less than 10% of wood pulp, but is one of the most controversial issues.
What do many paper companies do to ensure the health of forests?
The answer is the following: plant trees

Students attending BYU are required to follow an honor code, which mandates behavior in line with LDS teachings such as academic honesty, adherence to dress and grooming standards, and abstinence from extramarital sex and from the consumption of drugs and alcohol. Many students (88 percent of men, 33 percent of women) either delay enrollment or take a hiatus from their studies to serve as Mormon missionaries. (Men typically serve for two-years, while women serve for 18 months.) An education at BYU is also less expensive than at similar private universities, since "a significant portion" of the cost of operating the university is subsidized by the church's tithing funds.
What is the basis of the behavioral code at BYU?
LDS teachings

Input: Data compression
To determine what information in an audio signal is perceptually irrelevant, most lossy compression algorithms use transforms such as the modified discrete cosine transform (MDCT) to convert time domain sampled waveforms into a transform domain. Once transformed, typically into the frequency domain, component frequencies can be allocated bits according to how audible they are. Audibility of spectral components calculated using the absolute threshold of hearing and the principles of simultaneous maskingthe phenomenon wherein a signal is masked by another signal separated by frequencyand, in some cases, temporal maskingwhere a signal is masked by another signal separated by time. Equal-loudness contours may also be used to weight the perceptual importance of components. Models of the human ear-brain combination incorporating such effects are often called psychoacoustic models.

What are often called psychoacoustic models?
Output: Models of the human ear-brain

Input: Article: The sector, a calculating instrument used for solving problems in proportion, trigonometry, multiplication and division, and for various functions, such as squares and cube roots, was developed in the late 16th century and found application in gunnery, surveying and navigation.

Now answer this question: The sector, a calculating instrument, was invented during what century?

Output: 16th century

Problem: Eton's best-known holiday takes place on the so-called "Fourth of June", a celebration of the birthday of King George III, Eton's greatest patron. This day is celebrated with the Procession of Boats, in which the top rowing crews from the top four years row past in vintage wooden rowing boats. Similar to the Queen's Official Birthday, the "Fourth of June" is no longer celebrated on 4 June, but on the Wednesday before the first weekend of June. Eton also observes St. Andrew's Day, on which the Eton wall game is played.[citation needed]
What is Eton's best-known holiday?
The answer is the following:
"Fourth of June"
