Input: Multiracial American
Of numerous relationships between male slaveholders, overseers, or master's sons and women slaves, the most notable is likely that of President Thomas Jefferson with his slave Sally Hemings. As noted in the 2012 collaborative Smithsonian-Monticello exhibit, Slavery at Monticello: The Paradox of Liberty, Jefferson, then a widower, took Hemings as his concubine for nearly 40 years. They had six children of record; four Hemings children survived into adulthood, and he freed them all, among the very few slaves he freed. Two were allowed to "escape" to the North in 1822, and two were granted freedom by his will upon his death in 1826. Seven-eighths white by ancestry, all four of his Hemings children moved to northern states as adults; three of the four entered the white community, and all their descendants identified as white. Of the descendants of Madison Hemings, who continued to identify as black, some in future generations eventually identified as white and "married out", while others continued to identify as African American. It was socially advantageous for the Hemings children to identify as white, in keeping with their appearance and the majority proportion of their ancestry. Although born into slavery, the Hemings children were legally white under Virginia law of the time.

President Thomas Jefferson had a relationship with who?
Output: Sally Hemings

Input: Treaty
There are several reasons an otherwise valid and agreed upon treaty may be rejected as a binding international agreement, most of which involve problems created at the formation of the treaty.[citation needed] For example, the serial Japan-Korea treaties of 1905, 1907 and 1910 were protested; and they were confirmed as "already null and void" in the 1965 Treaty on Basic Relations between Japan and the Republic of Korea.

What treaties between Japan and Korea are examples of treaties that were declared null and void?
Output: the serial Japan-Korea treaties of 1905, 1907 and 1910

Input: Professional wrestling
Also, anything that can be used as an element of drama can exist in professional wrestling stories: romantic relationships (including love triangles and marriage), racism, classism, nepotism, favoritism, corporate corruption, family bonds, personal histories, grudges, theft, cheating, assault, betrayal, bribery, seduction, stalking, confidence tricks, extortion, blackmail, substance abuse, self-doubt, self-sacrifice; even kidnapping, sexual fetishism, necrophilia, misogyny, rape and death have been portrayed in wrestling. Some promotions have included supernatural elements such as magic, curses, the undead and Satanic imagery (most notably The Undertaker and his Ministry of Darkness, a stable that regularly performed evil rituals and human sacrifice in Satanic-like worship of a hidden power figure). Celebrities would also be involved in storylines.

What supernatural things have been portrayed in matches?
Output: magic, curses, the undead and Satanic imagery

Input: LaserDisc
Sound could be stored in either analog or digital format and in a variety of surround sound formats; NTSC discs could carry two analog audio tracks, plus two uncompressed PCM digital audio tracks, which were (EFM, CIRC, 16-bit and 44.056 kHz sample rate). PAL discs could carry one pair of audio tracks, either analog or digital and the digital tracks on a PAL disc were 16-bit 44.1 kHz as on a CD; in the UK, the term "LaserVision" is used to refer to discs with analog sound, while "LaserDisc" is used for those with digital audio. The digital sound signal in both formats are EFM-encoded as in CD. Dolby Digital (also called AC-3) and DTSwhich are now common on DVD titlesfirst became available on LaserDisc, and Star Wars: Episode I The Phantom Menace (1999) which was released on LaserDisc in Japan, is among the first home video releases ever to include 6.1 channel Dolby Digital EX Surround. Unlike DVDs, which carry Dolby Digital audio in digital form, LaserDiscs store Dolby Digital in a frequency modulated form within a track normally used for analog audio. Extracting Dolby Digital from a LaserDisc required a player equipped with a special "AC-3 RF" output and an external demodulator in addition to an AC-3 decoder. The demodulator was necessary to convert the 2.88 MHz modulated AC-3 information on the disc into a 384 kbit/s signal that the decoder could handle. DTS audio, when available on a disc, replaced the digital audio tracks; hearing DTS sound required only an S/PDIF compliant digital connection to a DTS decoder.

What was the difference between LaserDisc and LaserVision in the UK?
Output:
"LaserVision" is used to refer to discs with analog sound, while "LaserDisc" is used for those with digital audio
