Problem: Exhibition game:

However, from 1971 to 1975, NBA teams played preseason exhibitions against American Basketball Association teams. In the early days of the NBA, league clubs sometimes challenged the legendary barnstorming Harlem Globetrotters, with mixed success. The NBA has played preseason games in Europe and Asia. In the 2006 and 2007 seasons, the NBA and the primary European club competition, the Euroleague, conducted a preseason tournament featuring two NBA teams and the finalists from that year's Euroleague.[citation needed] In the 1998-99 and 2011-12 seasons, teams were limited to only two preseason games due to lockouts.

When did the NBA play preseason games against the ABA?

A: 1971 to 1975

Problem: The Kuru kingdom was the first state-level society of the Vedic period, corresponding to the beginning of the Iron Age in northwestern India, around 1200 800 BCE, as well as with the composition of the Atharvaveda (the first Indian text to mention iron, as syama ayas, literally "black metal"). The Kuru state organized the Vedic hymns into collections, and developed the orthodox srauta ritual to uphold the social order. When the Kuru kingdom declined, the center of Vedic culture shifted to their eastern neighbours, the Panchala kingdom. The archaeological Painted Grey Ware culture, which flourished in the Haryana and western Uttar Pradesh regions of northern India from about 1100 to 600 BCE, is believed to correspond to the Kuru and Panchala kingdoms.
What is the dating of the Kuru kingdom?

Answer: 1200 800 BCE

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Early court cases focused on the liability of Internet service providers (ISPs) for hosting, transmitting or publishing user-supplied content that could be actioned under civil or criminal law, such as libel, defamation, or pornography. As different content was considered in different legal systems, and in the absence of common definitions for "ISPs," "bulletin boards" or "online publishers," early law on online intermediaries' liability varied widely from country to country. The first laws on online intermediaries' liability were passed from the mid-1990s onwards.[citation needed]
When were the first laws of liability passed?
A: mid-1990s

Context and question: Development of the methods used in modern printed circuit boards started early in the 20th century. In 1903, a German inventor, Albert Hanson, described flat foil conductors laminated to an insulating board, in multiple layers. Thomas Edison experimented with chemical methods of plating conductors onto linen paper in 1904. Arthur Berry in 1913 patented a print-and-etch method in Britain, and in the United States Max Schoop obtained a patent to flame-spray metal onto a board through a patterned mask. Charles Ducas in 1927 patented a method of electroplating circuit patterns.
In Germany Max Schoop obtained a patent to do what?
Answer: unanswerable

Question: A new index was released on December 18, 2008. This so-called "statistical update" covered the period up to 2006 and was published without an accompanying Human Development Report. The update is relevant due to newly released estimates of purchasing power parities (PPP), implying substantial adjustments for many countries, resulting in changes in HDI values and, in many cases, HDI ranks.
Is there an answer to this question: What type of update was released on December 18, 2004?

Answer: unanswerable

Question: The first law of thermodynamics asserts that energy (but not necessarily thermodynamic free energy) is always conserved and that heat flow is a form of energy transfer. For homogeneous systems, with a well-defined temperature and pressure, a commonly used corollary of the first law is that, for a system subject only to pressure forces and heat transfer (e.g., a cylinder-full of gas) without chemical changes, the differential change in the internal energy of the system (with a gain in energy signified by a positive quantity) is given as
Is there an answer to this question: The first law of thermodynamics asserts that what is always conserved and that heat flow is a form of energy transfer?

Answer:
energy
