Input: Read this: Linking the information back together is the key to this system. In the relational model, some bit of information was used as a "key", uniquely defining a particular record. When information was being collected about a user, information stored in the optional tables would be found by searching for this key. For instance, if the login name of a user is unique, addresses and phone numbers for that user would be recorded with the login name as its key. This simple "re-linking" of related data back into a single collection is something that traditional computer languages are not designed for.
Question: How is data in an optional table removed?

Output: unanswerable

A mummified man, determined to be 5,000 years old, was discovered on a glacier at the AustrianItalian border in 1991. By the 6th century BC, the Celtic La Tene culture was well established. Hannibal famously crossed the Alps with a herd of elephants, and the Romans had settlements in the region. In 1800 Napoleon crossed one of the mountain passes with an army of 40,000. The 18th and 19th centuries saw an influx of naturalists, writers, and artists, in particular the Romantics, followed by the golden age of alpinism as mountaineers began to ascend the peaks. In World War II, Adolf Hitler kept a base of operation in the Bavarian Alps throughout the war.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How old was the mummified man discovered at the Austrian-Italian bored?
Ah, so.. 5,000 years old

Question: In the past, those who were disabled were often not eligible for public education. Children with disabilities were repeatedly denied an education by physicians or special tutors. These early physicians (people like Itard, Seguin, Howe, Gallaudet) set the foundation for special education today. They focused on individualized instruction and functional skills. In its early years, special education was only provided to people with severe disabilities, but more recently it has been opened to anyone who has experienced difficulty learning.
Try to answer this question if possible: Who didn't deny children with disabilities to be unable to attend a public school?
Answer: unanswerable

Question: Scholar Patrick Chura, who suggests Emmett Till was a model for Tom Robinson, enumerates the injustices endured by the fictional Tom that Till also faced. Chura notes the icon of the black rapist causing harm to the representation of the "mythologized vulnerable and sacred Southern womanhood". Any transgressions by black males that merely hinted at sexual contact with white females during the time the novel was set often resulted in a punishment of death for the accused. Tom Robinson's trial was juried by poor white farmers who convicted him despite overwhelming evidence of his innocence, as more educated and moderate white townspeople supported the jury's decision. Furthermore, the victim of racial injustice in To Kill a Mockingbird was physically impaired, which made him unable to commit the act he was accused of, but also crippled him in other ways. Roslyn Siegel includes Tom Robinson as an example of the recurring motif among white Southern writers of the black man as "stupid, pathetic, defenseless, and dependent upon the fair dealing of the whites, rather than his own intelligence to save him". Although Tom is spared from being lynched, he is killed with excessive violence during an attempted escape from prison, shot seventeen times.
Try to answer this question if possible: At the time of the novel's setting, what punishment was often received by black males for percieved sexual contact with a white woman?
Answer:
death
