Input: Dog
Emigrants from Siberia that walked across the Bering land bridge into North America may have had dogs in their company, and one writer suggests that the use of sled dogs may have been critical to the success of the waves that entered North America roughly 12,000 years ago, although the earliest archaeological evidence of dog-like canids in North America dates from about 9,400 years ago.:104 Dogs were an important part of life for the Athabascan population in North America, and were their only domesticated animal. Dogs also carried much of the load in the migration of the Apache and Navajo tribes 1,400 years ago. Use of dogs as pack animals in these cultures often persisted after the introduction of the horse to North America.

Dogs were the only domesticated animals for what North American population?
Output: Athabascan

Input: Szlachta
Some historians estimate the number of magnates as 1% of the number of szlachta. Out of approx. one million szlachta, tens of thousands of families, only 200300 persons could be classed as great magnates with country-wide possessions and influence, and 3040 of them could be viewed as those with significant impact on Poland's politics.

Historians estimate how much of magnates make up szlachta?
Output: 1%

Input: Hunting
Furthermore, evidence exists that hunting may have been one of the multiple environmental factors leading to extinctions of the holocene megafauna and their replacement by smaller herbivores. North American megafauna extinction was coincidental with the Younger Dryas impact event, possibly making hunting a less critical factor in prehistoric species loss than had been previously thought. However, in other locations such as Australia, humans are thought to have played a very significant role in the extinction of the Australian megafauna that was widespread prior to human occupation.

When was Australian's megafauna widespread?
Output: prior to human occupation

Input: Marvel Comics
In 1961, writer-editor Stan Lee revolutionized superhero comics by introducing superheroes designed to appeal to more all-ages readers than the predominantly child audiences of the medium. Modern Marvel's first superhero team, the titular stars of The Fantastic Four #1 (Nov. 1961), broke convention with other comic book archetypes of the time by squabbling, holding grudges both deep and petty, and eschewing anonymity or secret identities in favor of celebrity status. Subsequently, Marvel comics developed a reputation for focusing on characterization and adult issues to a greater extent than most superhero comics before them, a quality which the new generation of older readers appreciated. This applied to The Amazing Spider-Man title in particular, which turned out to be Marvel's most successful book. Its young hero suffered from self-doubt and mundane problems like any other teenager, something readers could identify with.

What Marvel executive helped change the focus of Marvel's stories and characters?
Output:
Stan Lee
