Input: Read this: Terrestrial annelids can be invasive in some situations. In the glaciated areas of North America, for example, almost all native earthworms are thought to have been killed by the glaciers and the worms currently found in those areas are all introduced from other areas, primarily from Europe, and, more recently, from Asia. Northern hardwood forests are especially negatively impacted by invasive worms through the loss of leaf duff, soil fertility, changes in soil chemistry and the loss of ecological diversity. Especially of concern is Amynthas agrestis and at least one state (Wisconsin) has listed it as a prohibited species.
Question: Where did most of the current earthworms in glacial areas come from?

Output: Europe

Input: Read this: Both low-cost and luxury housing were built by the government in the Brasilia. The residential zones of the inner city are arranged into superquadras ("superblocks"): groups of apartment buildings along with a prescribed number and type of schools, retail stores, and open spaces. At the northern end of Lake Paranoa, separated from the inner city, is a peninsula with many fashionable homes, and a similar city exists on the southern lakeshore. Originally the city planners envisioned extensive public areas along the shores of the artificial lake, but during early development private clubs, hotels, and upscale residences and restaurants gained footholds around the water. Set well apart from the city are satellite cities, including Gama, Ceilandia, Taguatinga, Nucleo Bandeirante, Sobradinho, and Planaltina. These cities, with the exception of Gama and Sobradinho were not planned.
Question: Where is there a peninsula with luxury homes?

Output: the northern end of Lake Paranoa

Input: Read this: A public genome sequencing effort of cotton was initiated in 2007 by a consortium of public researchers. They agreed on a strategy to sequence the genome of cultivated, tetraploid cotton. "Tetraploid" means that cultivated cotton actually has two separate genomes within its nucleus, referred to as the A and D genomes. The sequencing consortium first agreed to sequence the D-genome relative of cultivated cotton (G. raimondii, a wild Central American cotton species) because of its small size and limited number of repetitive elements. It is nearly one-third the number of bases of tetraploid cotton (AD), and each chromosome is only present once.[clarification needed] The A genome of G. arboreum would be sequenced next. Its genome is roughly twice the size of G. raimondii's. Part of the difference in size between the two genomes is the amplification of retrotransposons (GORGE). Once both diploid genomes are assembled, then research could begin sequencing the actual genomes of cultivated cotton varieties. This strategy is out of necessity; if one were to sequence the tetraploid genome without model diploid genomes, the euchromatic DNA sequences of the AD genomes would co-assemble and the repetitive elements of AD genomes would assembly independently into A and D sequences respectively. Then there would be no way to untangle the mess of AD sequences without comparing them to their diploid counterparts.
Question: When did a group or researchers decide to sequence the genomic structure of diploid counterparts?

Output: unanswerable

Input: Read this: The mantle is equivalent to 10 to 15 Earth masses and is rich in water, ammonia and methane. As is customary in planetary science, this mixture is referred to as icy even though it is a hot, dense fluid. This fluid, which has a high electrical conductivity, is sometimes called a waterammonia ocean. The mantle may consist of a layer of ionic water in which the water molecules break down into a soup of hydrogen and oxygen ions, and deeper down superionic water in which the oxygen crystallises but the hydrogen ions float around freely within the oxygen lattice. At a depth of 7000 km, the conditions may be such that methane decomposes into diamond crystals that rain downwards like hailstones. Very-high-pressure experiments at the Lawrence Livermore National Laboratory suggest that the base of the mantle may comprise an ocean of liquid carbon with floating solid 'diamonds'.
Question: Who's mantle is 10 to 15 times greater than Neptunes?

Output:
unanswerable
