Question: The Silurian is a major division of the geologic timescale that started about 443.8 1.5 Ma. During the Silurian, Gondwana continued a slow southward drift to high southern latitudes, but there is evidence that the Silurian ice caps were less extensive than those of the late Ordovician glaciation. The melting of ice caps and glaciers contributed to a rise in sea levels, recognizable from the fact that Silurian sediments overlie eroded Ordovician sediments, forming an unconformity. Other cratons and continent fragments drifted together near the equator, starting the formation of a second supercontinent known as Euramerica. The vast ocean of Panthalassa covered most of the northern hemisphere. Other minor oceans include Proto-Tethys, Paleo-Tethys, Rheic Ocean, a seaway of Iapetus Ocean (now in between Avalonia and Laurentia), and newly formed Ural Ocean.
Is there an answer to this question: What continent continued to drift northward during the Silurian?

Answer: unanswerable

Question: Rajasthan is[when?] earning Rs. 150 million (approx. US$2.5 million) per day as revenue from the crude oil sector. This earning is expected to reach 250 million per day in 2013 (which is an increase of 100 million or more than 66 percent). The government of India has given permission to extract 300,000 barrels of crude per day from Barmer region which is now 175,000 barrels per day. Once this limit is achieved Rajasthan will become a leader in Crude extraction in Country. Bombay High leads with a production of 250,000 barrels crude per day. Once the limit if 300,000 barrels per day is reached, the overall production of the country will increase by 15 percent. Cairn India is doing the work of exploration and extraction of crude oil in Rajasthan.
Is there an answer to this question: How many barrels per day is currently being extracted from the Barmer region?

Answer: 175,000 barrels

Question: Agricultural diversity can also be divided by whether it is 'planned' diversity or 'associated' diversity. This is a functional classification that we impose and not an intrinsic feature of life or diversity. Planned diversity includes the crops which a farmer has encouraged, planted or raised (e.g.: crops, covers, symbionts and livestock, among others), which can be contrasted with the associated diversity that arrives among the crops, uninvited (e.g.: herbivores, weed species and pathogens, among others).
Is there an answer to this question: What type of diversity included the crops which a farmer has uninvited?

Answer:
unanswerable
