Problem: Baptists:

Leading up to the American Civil War, Baptists became embroiled in the controversy over slavery in the United States. Whereas in the First Great Awakening, Methodist and Baptist preachers had opposed slavery and urged manumission, over the decades they made more of an accommodation with the institution. They worked with slaveholders in the South to urge a paternalistic institution. Both denominations made direct appeals to slaves and free blacks for conversion. The Baptists particularly allowed them active roles in congregations. By the mid-19th century, northern Baptists tended to oppose slavery. As tensions increased, in 1844 the Home Mission Society refused to appoint a slaveholder as a missionary who had been proposed by Georgia. It noted that missionaries could not take servants with them, and also that the Board did not want to appear to condone slavery.

When did Methodist and Baptist preachers promote slavery and urge manumission?

Problem: Among all 17 railway stations in Nanjing, passenger rail service is mainly provided by Nanjing Railway Station and Nanjing South Railway Station, while other stations like Nanjing West Railway Station, Zhonghuamen Railway Station and Xianlin Railway Station serve minor roles. Nanjing Railway Station was first built in 1968. In 1999, On November 12, 1999, the station was burnt in a serious fire. Reconstruction of the station was finished on September 1, 2005. Nanjing South Railway Station, which is one of the 5 hub stations on Beijing–Shanghai High-Speed Railway, has officially been claimed as the largest railway station in Asia and the second largest in the world in terms of GFA (Gross Floor Area). Construction of Nanjing South Station began on 10 January 2008. The station was opened for public service in 2011.
In what year was the Nanjing Railway Station re-built?

Answer: 2005

Fungi communicate to coordinate and organize their growth and development such as the formation of Marcelia and fruiting bodies. Fungi communicate with their own and related species as well as with non fungal organisms in a great variety of symbiotic interactions, especially with bacteria, unicellular eukaryote, plants and insects through biochemicals of biotic origin. The biochemicals trigger the fungal organism to react in a specific manner, while if the same chemical molecules are not part of biotic messages, they do not trigger the fungal organism to react. This implies that fungal organisms can differentiate between molecules taking part in biotic messages and similar molecules being irrelevant in the situation. So far five different primary signalling molecules are known to coordinate different behavioral patterns such as filamentation, mating, growth, and pathogenicity. Behavioral coordination and production of signaling substances is achieved through interpretation processes that enables the organism to differ between self or non-self, a biotic indicator, biotic message from similar, related, or non-related species, and even filter out "noise", i.e. similar molecules without biotic content.
How do fungi communicate with insects?
A: through biochemicals of biotic origin


Context and question: Numerous modern mandolin makers build instruments that largely replicate the Gibson F-5 Artist models built in the early 1920s under the supervision of Gibson acoustician Lloyd Loar. Original Loar-signed instruments are sought after and extremely valuable. Other makers from the Loar period and earlier include Lyon and Healy, Vega and Larson Brothers. Some notable modern American carved mandolin manufacturers include, in addition to Kay, Gibson, Weber, Monteleone and Collings. Mandolins from other countries include The Loar (China), Santa, Rosa (China), Michael Kelly (Korea), Eastman (China), Kentucky (China), Heiden (Canada), Gilchrist (Australia) and Morgan Monroe (China).
What style of Gisbon Mandolin was never replicated?
Answer: unanswerable


Question: The port was the point of departure for the Pilgrim Fathers aboard Mayflower in 1620. In 1912, the RMS Titanic sailed from Southampton. Four in five of the crew on board the vessel were Sotonians, with about a third of those who perished in the tragedy hailing from the city. Southampton was subsequently the home port for the transatlantic passenger services operated by Cunard with their Blue Riband liner RMS Queen Mary and her running mate RMS Queen Elizabeth. In 1938, Southampton docks also became home to the flying boats of Imperial Airways. Southampton Container Terminals first opened in 1968 and has continued to expand.
Is there an answer to this question: How many crew members out of every five on the RMS Titanic were Sotonians?

Answer: Four

Another approach to hardware support for database management was ICL's CAFS accelerator, a hardware disk controller with programmable search capabilities. In the long term, these efforts were generally unsuccessful because specialized database machines could not keep pace with the rapid development and progress of general-purpose computers. Thus most database systems nowadays are software systems running on general-purpose hardware, using general-purpose computer data storage. However this idea is still pursued for certain applications by some companies like Netezza and Oracle (Exadata).
Did the CAFS accelerator work as planned?
A:
efforts were generally unsuccessful
