Input: Crimean War
In August 1855 a Franco-British naval force captured and destroyed the Russian Bomarsund fortress on Aland Islands. In the same month, the Western Allied Baltic Fleet tried to destroy heavily defended Russian dockyards at Sveaborg outside Helsinki. More than 1000 enemy guns tested the strength of the fortress for two days. Despite the shelling, the sailors of the 120-gun ship Rossiya, led by Captain Viktor Poplonsky, defended the entrance to the harbor. The Allies fired over 20,000 shells but failed to defeat the Russian batteries. A massive new fleet of more than 350 gunboats and mortar vessels was prepared[by whom?], but before the attack was launched, the war ended.

When did the French and British capture the Russian Bomarsund fortress?
Output: August 1855

Input: Article: Even as the Western Roman empire collapsed, literate men acknowledged that Virgil was a master poet. Gregory of Tours read Virgil, whom he quotes in several places, along with some other Latin poets, though he cautions that "we ought not to relate their lying fables, lest we fall under sentence of eternal death."

Now answer this question: Literate men acknowledged Virgil as a master poet despite what empire collapsing?

Output: Western Roman

Article: According to most scholars, at some period after the Second Council the Sangha began to break into separate factions.[note 37] The various accounts differ as to when the actual schisms occurred. According to the Dipavamsa of the Pali tradition, they started immediately after the Second Council, the Puggalavada tradition places it in 137 AN, the Sarvastivada tradition of Vasumitra says it was in the time of Ashoka and the Mahasanghika tradition places it much later, nearly 100 BCE.

Question: The Mahasanghika places the breakup at what time?
Ans: 100 BCE

Here is a question about this article: It was not unusual for electric recordings to be played back on acoustic phonographs. The Victor Orthophonic phonograph was a prime example where such playback was expected. In the Orthophonic, which benefited from telephone research, the mechanical pickup head was redesigned with lower resonance than the traditional mica type. Also, a folded horn with an exponential taper was constructed inside the cabinet to provide better impedance matching to the air. As a result, playback of an Orthophonic record sounded like it was coming from a radio.
What is the answer to this question: How similar was the sound of a orthodontic record to a radio?
****
So... sounded like

The problem: Answer a question about this article:
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.
How old are the oldest findings of dogs in North America?
****
The answer: 9,400 years

The problem: Answer a question about this article:
The climatic changes of the late Jurassic and Cretaceous provided for further adaptive radiation. The Jurassic was the height of archosaur diversity, and the first birds and eutherian mammals also appeared. Angiosperms radiated sometime in the early Cretaceous, first in the tropics, but the even temperature gradient allowed them to spread toward the poles throughout the period. By the end of the Cretaceous, angiosperms dominated tree floras in many areas, although some evidence suggests that biomass was still dominated by cycad and ferns until after the CretaceousPaleogene extinction.
What event produced further adaptations during the Jurassic and Cretaceous periods?
****
The answer:
climatic changes
