Problem: In 2000, Dell announced that it would lease 80,000 square feet (7,400 m2) of space in the Las Cimas office complex in unincorporated Travis County, Texas, between Austin and West Lake Hills, to house the company's executive offices and corporate headquarters. 100 senior executives were scheduled to work in the building by the end of 2000. In January 2001, the company leased the space in Las Cimas 2, located along Loop 360. Las Cimas 2 housed Dell's executives, the investment operations, and some corporate functions. Dell also had an option for 138,000 square feet (12,800 m2) of space in Las Cimas 3. After a slowdown in business required reducing employees and production capacity, Dell decided to sublease its offices in two buildings in the Las Cimas office complex. In 2002 Dell announced that it planned to sublease its space to another tenant; the company planned to move its headquarters back to Round Rock once a tenant was secured. By 2003, Dell moved its headquarters back to Round Rock. It leased all of Las Cimas I and II, with a total of 312,000 square feet (29,000 m2), for about a seven-year period after 2003. By that year roughly 100,000 square feet (9,300 m2) of that space was absorbed by new subtenants.
What was the total amount of space that Dell leased in Las Cimas 1 and 2?
The answer is the following: 312,000 square feet

Windows 8 introduces a new style of application, Windows Store apps. According to Microsoft developer Jensen Harris, these apps are to be optimized for touchscreen environments and are more specialized than current desktop applications. Apps can run either in a full-screen mode, or be snapped to the side of a screen. Apps can provide toast notifications on screen or animate their tiles on the Start screen with dynamic content. Apps can use "contracts"; a collection of hooks to provide common functionality that can integrate with other apps, including search and sharing. Apps can also provide integration with other services; for example, the People app can connect to a variety of different social networks and services (such as Facebook, Skype, and People service), while the Photos app can aggregate photos from services such as Facebook and Flickr.

Input: History of science
Modern geology, like modern chemistry, gradually evolved during the 18th and early 19th centuries. Benoit de Maillet and the Comte de Buffon saw the Earth as much older than the 6,000 years envisioned by biblical scholars. Jean-Etienne Guettard and Nicolas Desmarest hiked central France and recorded their observations on some of the first geological maps. Aided by chemical experimentation, naturalists such as Scotland's John Walker, Sweden's Torbern Bergman, and Germany's Abraham Werner created comprehensive classification systems for rocks and mineralsa collective achievement that transformed geology into a cutting edge field by the end of the eighteenth century. These early geologists also proposed a generalized interpretations of Earth history that led James Hutton, Georges Cuvier and Alexandre Brongniart, following in the steps of Steno, to argue that layers of rock could be dated by the fossils they contained: a principle first applied to the geology of the Paris Basin. The use of index fossils became a powerful tool for making geological maps, because it allowed geologists to correlate the rocks in one locality with those of similar age in other, distant localities. Over the first half of the 19th century, geologists such as Charles Lyell, Adam Sedgwick, and Roderick Murchison applied the new technique to rocks throughout Europe and eastern North America, setting the stage for more detailed, government-funded mapping projects in later decades.

In the 18th century, what changed geology drastically?
Output: comprehensive classification systems for rocks and minerals

Article: Since 1965, following clashes between the two communities, the Turkish Cypriot seats in the House remain vacant. In 1974 Cyprus was divided de facto when the Turkish army occupied the northern third of the island. The Turkish Cypriots subsequently declared independence in 1983 as the Turkish Republic of Northern Cyprus but were recognised only by Turkey. In 1985 the TRNC adopted a constitution and held its first elections. The United Nations recognises the sovereignty of the Republic of Cyprus over the entire island of Cyprus.

Question: Which part of Cyprus was occupied by the Turkish army?
Ans: northern third of the island

Input: Biodiversity
The number of species invasions has been on the rise at least since the beginning of the 1900s. Species are increasingly being moved by humans (on purpose and accidentally). In some cases the invaders are causing drastic changes and damage to their new habitats (e.g.: zebra mussels and the emerald ash borer in the Great Lakes region and the lion fish along the North American Atlantic coast). Some evidence suggests that invasive species are competitive in their new habitats because they are subject to less pathogen disturbance. Others report confounding evidence that occasionally suggest that species-rich communities harbor many native and exotic species simultaneously while some say that diverse ecosystems are more resilient and resist invasive plants and animals. An important question is, "do invasive species cause extinctions?" Many studies cite effects of invasive species on natives, but not extinctions. Invasive species seem to increase local (i.e.: alpha diversity) diversity, which decreases turnover of diversity (i.e.: beta diversity). Overall gamma diversity may be lowered because species are going extinct because of other causes, but even some of the most insidious invaders (e.g.: Dutch elm disease, emerald ash borer, chestnut blight in North America) have not caused their host species to become extinct. Extirpation, population decline, and homogenization of regional biodiversity are much more common. Human activities have frequently been the cause of invasive species circumventing their barriers, by introducing them for food and other purposes. Human activities therefore allow species to migrate to new areas (and thus become invasive) occurred on time scales much shorter than historically have been required for a species to extend its range.

What invaders are causing changes along the North American Atlantic coast?
Output:
lion fish
