Problem: Chihuahua (state):

The United States Congress declared war on Mexico on May 13, 1846 after only having a few hours to debate. Although President Jose Mariano Paredes's issuance of a manifesto on May 23 is sometimes considered the declaration of war, Mexico officially declared war by Congress on July 7. After the American invasion of New Mexico, Chihuahua sent 12,000 men led by Colonel Vidal to the border to stop the American military advance into the state. The Mexican forces being impatient to confront the American forces passed beyond El Paso del Norte about 20 miles (32 km) north along the Rio Grande. The first battle that Chihuahua fought was the battle of El Bracito; the Mexican forces consisting of 500 cavalry and 70 infantry confronted a force of 1,1001,200 Americans on December 25, 1846. The battle ended badly by the Mexican forces that were then forced to retreat back into the state of Chihuahua. By December 27, 1846, the American forces occupied El Paso Del Norte. General Doniphan maintained camp in El Paso Del Norte awaiting supplies and artillery which he received in February 1847.

Which general maintained camp in El Paso Del Norte after the battle?
---
A: General Doniphan

Problem: As of September 2012, fifty-six species have been delisted; twenty-eight due to recovery, ten due to extinction (seven of which are believed to have been extinct prior to being listed), ten due to changes in taxonomic classification practices, six due to discovery of new populations, one due to an error in the listing rule, and one due to an amendment to the Endangered Species Act specifically requiring the species delisting. Twenty-five others have been down listed from "endangered" to "threatened" status.
How many new populations were lost?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The only extant depiction of Edward's abbey, together with the adjacent Palace of Westminster, is in the Bayeux Tapestry. Some of the lower parts of the monastic dormitory, an extension of the South Transept, survive in the Norman undercroft of the Great School, including a door said to come from the previous Saxon abbey. Increased endowments supported a community increased from a dozen monks in Dunstan's original foundation, up to a maximum about eighty monks, although there was also a large community of lay brothers who supported the monastery's extensive property and activities.
Where is the only existant depiction of Edward's abbey?
A: Bayeux Tapestry

Context and question: The Atlantic coast of the United States is low, with minor exceptions. The Appalachian Highland owes its oblique northeast-southwest trend to crustal deformations which in very early geological time gave a beginning to what later came to be the Appalachian mountain system. This system had its climax of deformation so long ago (probably in Permian time) that it has since then been very generally reduced to moderate or low relief. It owes its present-day altitude either to renewed elevations along the earlier lines or to the survival of the most resistant rocks as residual mountains. The oblique trend of this coast would be even more pronounced but for a comparatively modern crustal movement, causing a depression in the northeast resulting in an encroachment of the sea upon the land. Additionally, the southeastern section has undergone an elevation resulting in the advance of the land upon the sea.
What made to see advance on the land in the southeasternAppalachian?
Answer: unanswerable

Question: After Demetrius' death, civil wars between Bactrian kings in India allowed Apollodotus I (from c. 180/175 BCE) to make himself independent as the first proper Indo-Greek king (who did not rule from Bactria). Large numbers of his coins have been found in India, and he seems to have reigned in Gandhara as well as western Punjab. Apollodotus I was succeeded by or ruled alongside Antimachus II, likely the son of the Bactrian king Antimachus I. In about 155 (or 165) BC he seems to have been succeeded by the most successful of the Indo-Greek kings, Menander I. Menander converted to Buddhism, and seems to have been a great patron of the religion; he is remembered in some Buddhist texts as 'Milinda'. He also expanded the kingdom further east into Punjab, though these conquests were rather ephemeral.
Is there an answer to this question: What religion did Menander I convert to?

Answer: Buddhism

Question: The demographics of the British Isles today are characterised by a generally high density of population in England, which accounts for almost 80% of the total population of the islands. In elsewhere on Great Britain and on Ireland, high density of population is limited to areas around, or close to, a few large cities. The largest urban area by far is the Greater London Urban Area with 9 million inhabitants. Other major populations centres include Greater Manchester Urban Area (2.4 million), West Midlands conurbation (2.4 million), West Yorkshire Urban Area (1.6 million) in England, Greater Glasgow (1.2 million) in Scotland and Greater Dublin Area (1.1 million) in Ireland.[citation needed]
Is there an answer to this question: Which is the smallest urban area with only 9 million people?

Answer:
unanswerable
