In Chapter II, Darwin specifies that the distinction between species and varieties is arbitrary, with experts disagreeing and changing their decisions when new forms were found. He concludes that "a well-marked variety may be justly called an incipient species" and that "species are only strongly marked and permanent varieties". He argues for the ubiquity of variation in nature. Historians have noted that naturalists had long been aware that the individuals of a species differed from one another, but had generally considered such variations to be limited and unimportant deviations from the archetype of each species, that archetype being a fixed ideal in the mind of God. Darwin and Wallace made variation among individuals of the same species central to understanding the natural world.

What does Darwin believe about the differences between species and varieties?
Answer: is arbitrary

Problem: Candidates for Freemasonry will have met most active members of the Lodge they are joining before they are initiated. The process varies between jurisdictions, but the candidate will typically have been introduced by a friend at a Lodge social function, or at some form of open evening in the Lodge. In modern times, interested people often track down a local Lodge through the Internet. The onus is on candidates to ask to join; while candidates may be encouraged to ask, they are never invited. Once the initial inquiry is made, an interview usually follows to determine the candidate's suitability. If the candidate decides to proceed from here, the Lodge ballots on the application before he (or she, depending on the Masonic Jurisdiction) can be accepted.
Candidates for Freemasonry must do what before being initiated?
The answer is the following: will have met most active members of the Lodge they are joining

Roughly 70% of the area in the RSFSR consisted of broad plains, with mountainous tundra regions mainly concentrated in the east. The area is rich in mineral resources, including petroleum, natural gas, and iron ore.
In what part of the RSFSR did tundra mainly exist?
the east

Input: University of Kansas
KU's School of Business launched interdisciplinary management science graduate studies in operations research during Fall Semester 1965. The program provided the foundation for decision science applications supporting NASA Project Apollo Command Capsule Recovery Operations.

What NASA program benefited from the use of decision science applications?
Output: NASA Project Apollo Command Capsule Recovery Operations

Input: Article: Schwarzenegger was born with a bicuspid aortic valve, an aortic valve with only two leaflets (a normal aortic valve has three leaflets). Schwarzenegger opted in 1997 for a replacement heart valve made of his own transplanted tissue; medical experts predicted he would require heart valve replacement surgery in the following two to eight years as his valve would progressively degrade. Schwarzenegger apparently opted against a mechanical valve, the only permanent solution available at the time of his surgery, because it would have sharply limited his physical activity and capacity to exercise.

Now answer this question: Schwarzenegger underwent heart valve replacement in what year?

Output: 1997

Problem: Crevasses can form in several different ways. Transverse crevasses are transverse to flow and form where steeper slopes cause a glacier to accelerate. Longitudinal crevasses form semi-parallel to flow where a glacier expands laterally. Marginal crevasses form from the edge of the glacier, due to the reduction in speed caused by friction of the valley walls. Marginal crevasses are usually largely transverse to flow. Moving glacier ice can sometimes separate from stagnant ice above, forming a bergschrund. Bergschrunds resemble crevasses but are singular features at a glacier's margins.
Where do transverse crevasses form?
The answer is the following:
where steeper slopes cause a glacier to accelerate
