Problem: Please answer a question about the following article about Film speed:
The system was later extended to cover larger ranges and some of its practical shortcomings were addressed by the Austrian scientist Josef Maria Eder (18551944) and Flemish-born botanist Walter Hecht (de) (18961960), (who, in 1919/1920, jointly developed their EderHecht neutral wedge sensitometer measuring emulsion speeds in EderHecht grades). Still, it remained difficult for manufactures to reliably determine film speeds, often only by comparing with competing products, so that an increasing number of modified semi-Scheiner-based systems started to spread, which no longer followed Scheiner's original procedures and thereby defeated the idea of comparability.
Who developed a device that improved on the shortcomings of Scheiner's invention?
A: Austrian scientist Josef Maria Eder (18551944) and Flemish-born botanist Walter Hecht (de)
Problem: Please answer a question about the following article about Hydrogen:
In its turn, under anaerobic conditions, the ferrous hydroxide (Fe(OH)
2 ) can be oxidized by the protons of water to form magnetite and molecular hydrogen. This process is described by the Schikorr reaction:
What reaction describes this process?
A: Schikorr reaction
Problem: Please answer a question about the following article about Paris:
In Paris' Roman era, its main cemetery was located to the outskirts of the Left Bank settlement, but this changed with the rise of Catholicism, where most every inner-city church had adjoining burial grounds for use by their parishes. With Paris' growth many of these, particularly the city's largest cemetery, les Innocents, were filled to overflowing, creating quite unsanitary conditions for the capital. When inner-city burials were condemned from 1786, the contents of all Paris' parish cemeteries were transferred to a renovated section of Paris' stone mines outside the "Porte d'Enfer" city gate, today place Denfert-Rochereau in the 14th arrondissement. The process of moving bones from Cimetiere des Innocents to the catacombs took place between 1786 and 1814; part of the network of tunnels and remains can be visited today on the official tour of the catacombs.
During what years were the bones moved from Cimetiere des Innocents to the catacombs?
A: 1786 and 1814

What waterfront park hosts the Boat Show?
A:
Mayflower Park
