Input: Botany
Judging relationships based on shared characters requires care, since plants may resemble one another through convergent evolution in which characters have arisen independently. Some euphorbias have leafless, rounded bodies adapted to water conservation similar to those of globular cacti, but characters such as the structure of their flowers make it clear that the two groups are not closely related. The cladistic method takes a systematic approach to characters, distinguishing between those that carry no information about shared evolutionary history such as those evolved separately in different groups (homoplasies) or those left over from ancestors (plesiomorphies) and derived characters, which have been passed down from innovations in a shared ancestor (apomorphies). Only derived characters, such as the spine-producing areoles of cacti, provide evidence for descent from a common ancestor. The results of cladistic analyses are expressed as cladograms: tree-like diagrams showing the pattern of evolutionary branching and descent.

How can two different plants acquire the same traits?
Output: arisen independently

Input: Article: The vast majority of living organisms encode their genes in long strands of DNA (deoxyribonucleic acid). DNA consists of a chain made from four types of nucleotide subunits, each composed of: a five-carbon sugar (2'-deoxyribose), a phosphate group, and one of the four bases adenine, cytosine, guanine, and thymine.:2.1

Now answer this question: What do the vast majority of living organisms encode their genes in?

Output: long strands of DNA (deoxyribonucleic acid)

Article: In recent years there was a high demand for massively distributed databases with high partition tolerance but according to the CAP theorem it is impossible for a distributed system to simultaneously provide consistency, availability and partition tolerance guarantees. A distributed system can satisfy any two of these guarantees at the same time, but not all three. For that reason many NoSQL databases are using what is called eventual consistency to provide both availability and partition tolerance guarantees with a reduced level of data consistency.

Question: What explains the difficulty in a system containing availability, consistency, and partition tolerance guarantees?
Ans: the CAP theorem

Here is a question about this article: The 1903 advent of heavier-than-air fixed-wing aircraft was closely followed in 1910 by the first experimental take-off of an airplane, made from the deck of a United States Navy vessel (cruiser USS Birmingham), and the first experimental landings were conducted in 1911. On 9 May 1912 the first airplane take-off from a ship underway was made from the deck of the British Royal Navy's HMS Hibernia. Seaplane tender support ships came next, with the French Foudre of 1911. In September 1914 the Imperial Japanese Navy Wakamiya conducted the world's first successful ship-launched air raid: on 6 September 1914 a Farman aircraft launched by Wakamiya attacked the Austro-Hungarian cruiser SMS Kaiserin Elisabeth and the German gunboat Jaguar in Kiaochow Bay off Tsingtao; neither was hit. The first carrier-launched airstrike was the Tondern Raid in July 1918. Seven Sopwith Camels launched from the converted battlecruiser HMS Furious damaged the German airbase at Tnder and destroyed two zeppelins.
What is the answer to this question: What was the first carrier-launched airstrike?
****
So... the Tondern Raid in July 1918

The problem: Answer a question about this article:
The FAA gradually assumed additional functions. The hijacking epidemic of the 1960s had already brought the agency into the field of civil aviation security. In response to the hijackings on September 11, 2001, this responsibility is now primarily taken by the Department of Homeland Security. The FAA became more involved with the environmental aspects of aviation in 1968 when it received the power to set aircraft noise standards. Legislation in 1970 gave the agency management of a new airport aid program and certain added responsibilities for airport safety. During the 1960s and 1970s, the FAA also started to regulate high altitude (over 500 feet) kite and balloon flying.
Who now takes responsibility for aviation security?
****
The answer: Department of Homeland Security

North Carolinians enjoy outdoor recreation utilizing numerous local bike paths, 34 state parks, and 14 national parks. National Park Service units include the Appalachian National Scenic Trail, the Blue Ridge Parkway, Cape Hatteras National Seashore, Cape Lookout National Seashore, Carl Sandburg Home National Historic Site at Flat Rock, Fort Raleigh National Historic Site at Manteo, Great Smoky Mountains National Park, Guilford Courthouse National Military Park in Greensboro, Moores Creek National Battlefield near Currie in Pender County, the Overmountain Victory National Historic Trail, Old Salem National Historic Site in Winston-Salem, the Trail of Tears National Historic Trail, and Wright Brothers National Memorial in Kill Devil Hills. National Forests include Uwharrie National Forest in central North Carolina, Croatan National Forest in Eastern North Carolina, Pisgah National Forest in the northern mountains, and Nantahala National Forest in the southwestern part of the state.
Where is the Uwharrie national Forest located?
****
The answer:
central North Carolina
