[EX Q]: Passage: The spotted green pigeon or Liverpool pigeon (Caloenas maculata) is a species of pigeon which is most likely extinct. It was first mentioned and described in 1783 by John Latham, who had seen two specimens of unknown provenance and a drawing depicting the bird. The taxonomic relationships of the bird were long obscure, and early writers suggested many different possibilities, though the idea that it was related to the Nicobar pigeon (C. nicobarica) prevailed, and it was therefore placed in the same genus, Caloenas. Today, the species is only known from a specimen kept in World Museum, Liverpool. Overlooked for much of the 20th century, it was recognised as a valid extinct species by the IUCN Red List only in 2008. In 2014 a genetic study confirmed it as a distinct species related to the Nicobar pigeon, and showed that the two were the closest relatives of the extinct dodo and Rodrigues solitaire.
 Link Information: The animal order Columbiformes is also constituted of pigeons and doves, and includes about 42 genera and 310 species.
 Answer: 310

[EX Q]: Passage: Ice Mountain is an arc-shaped forested ridge of the Allegheny Mountains, part of the Ridge-and-valley Appalachians. It is above mean sea level at its summit. Ice Mountain is a large mass of Devonian Oriskany (Ridgeley) sandstone and Marcellus shale with numerous bare rock slopes and vertical cliffs. Ice Mountain lies on the west side of the Timber Mountain anticline and to the west of North Mountain fault, which places it on the Martinsburg allochthonous sheet. Ice Mountain is situated along North River and is known for the several hundred yards of ice that form at its base all year long. At its southern end overlooking the community of North River Mills is located Raven Rocks, a set of stone chimney outcrops. Raven Rocks is in height above mean sea level with vertical cliffs measuring nearly in height. Raven Rocks were named because of the presence of ravens during pioneer days. The present Raven Rocks is the remaining vestige of a once towering cliff that overlooked the North River. Geologically, Ice Mountain is a northern extension of North River Mountain.

[EX A]: How long is the river that Ice Mountain is alongside?

[EX Q]: Passage: The neighborhood is just west of the Federal Hill community and commercial district connected by West Hamburg Street, which is along South Charles and Light Streets, and the famous hill itself, which was the site of a celebratory picnic in 1788 after a parade of the various guilds, organizations and military units of old "Baltimore Town" to commemorate the ratification by Maryland of the new Federal Constitution, and later fortified with earthen embankments and large cannons of artillery by Northern troops of the Union Army a month after, during the Civil War to keep a close watch on and control on the Southern-sympathizing citizens of the City who had erupted in April 1861, in a riot attacking passing Massachusetts and Pennsylvania troops from the President Street Station on the east side from Philadelphia and the North, on their way to the nearby (a few blocks away with the Washington tracks running right by the Church) Camden Street Station of the famous Baltimore and Ohio Railroad to defend the National Capital of Washington from the newly seceded Virginians and Confederates.
