Problem: Destructive testing attempts to cause the software or a sub-system to fail. It verifies that the software functions properly even when it receives invalid or unexpected inputs, thereby establishing the robustness of input validation and error-management routines.[citation needed] Software fault injection, in the form of fuzzing, is an example of failure testing. Various commercial non-functional testing tools are linked from the software fault injection page; there are also numerous open-source and free software tools available that perform destructive testing.
What is one example of failure testing?
The answer is the following: Software fault injection

Problem: The Gateway Center at Bronx Terminal Market, in the West Bronx, is a shopping center that encompasses less than one million square feet of retail space, built on a 17 acres (7 ha) site that formerly held the Bronx Terminal Market, a wholesale fruit and vegetable market as well as the former Bronx House of Detention, south of Yankee Stadium. The $500 million shopping center, which was completed in 2009, saw the construction of new buildings and two smaller buildings, one new and the other a renovation of an existing building that was part of the original market. The two main buildings are linked by a six-level garage for 2,600 cars. The center has earned itself a LEED "Silver" designation in its design.
How many cars can the Gateway Center at Bronx Terminal Market's parking garage hold?
The answer is the following: 2,600

Problem: In 2005, seventeen countries produced concentrated uranium oxides, with Canada (27.9% of world production) and Australia (22.8%) being the largest producers and Kazakhstan (10.5%), Russia (8.0%), Namibia (7.5%), Niger (7.4%), Uzbekistan (5.5%), the United States (2.5%), Argentina (2.1%), Ukraine (1.9%) and China (1.7%) also producing significant amounts. Kazakhstan continues to increase production and may have become the world's largest producer of uranium by 2009 with an expected production of 12,826 tonnes, compared to Canada with 11,100 t and Australia with 9,430 t. In the late 1960s, UN geologists also discovered major uranium deposits and other rare mineral reserves in Somalia. The find was the largest of its kind, with industry experts estimating the deposits at over 25% of the world's then known uranium reserves of 800,000 tons.
As of 2005, what country was the largest producer of uranium oxides?
The answer is the following: Canada

Problem: The formation of the Alps (the Alpine orogeny) was an episodic process that began about 300 million years ago. In the Paleozoic Era the Pangaean supercontinent consisted of a single tectonic plate; it broke into separate plates during the Mesozoic Era and the Tethys sea developed between Laurasia and Gondwana during the Jurassic Period. The Tethys was later squeezed between colliding plates causing the formation of mountain ranges called the Alpide belt, from Gibraltar through the Himalayas to Indonesia—a process that began at the end of the Mesozoic and continues into the present. The formation of the Alps was a segment of this orogenic process, caused by the collision between the African and the Eurasian plates that began in the late Cretaceous Period.
The collision between the African and the Eurasian plates began during what time? 
The answer is the following:
the late Cretaceous Period
