Problem: The evolutionary relationships and heredity of a group of organisms is called its phylogeny. Phylogenetic studies attempt to discover phylogenies. The basic approach is to use similarities based on shared inheritance to determine relationships. As an example, species of Pereskia are trees or bushes with prominent leaves. They do not obviously resemble a typical leafless cactus such as an Echinocactus. However, both Pereskia and Echinocactus have spines produced from areoles (highly specialised pad-like structures) suggesting that the two genera are indeed related.
What does the phylogeny of a group represent?
The answer is the following: relationships and heredity

As a ray of white sunlight travels through the atmosphere to the eye, some of the colors are scattered out of the beam by air molecules and airborne particles due to Rayleigh scattering, changing the final color of the beam that is seen. Colors with a shorter wavelength, such as blue and green, scatter more strongly, and are removed from the light that finally reaches the eye. At sunrise and sunset, when the path of the sunlight through the atmosphere to the eye is longest, the blue and green components are removed almost completely, leaving the longer wavelength orange and red light. The remaining reddened sunlight can also be scattered by cloud droplets and other relatively large particles, which give the sky above the horizon its red glow.
What is the effect on blue and green light experiencing Rayleigh scattering during sunrise?
removed almost completely

Input: Dwight D. Eisenhower
In May 1955, McCarthy threatened to issue subpoenas to White House personnel. Eisenhower was furious, and issued an order as follows: "It is essential to efficient and effective administration that employees of the Executive Branch be in a position to be completely candid in advising with each other on official matters ... it is not in the public interest that any of their conversations or communications, or any documents or reproductions, concerning such advice be disclosed." This was an unprecedented step by Eisenhower to protect communication beyond the confines of a cabinet meeting, and soon became a tradition known as executive privilege. Ike's denial of McCarthy's access to his staff reduced McCarthy's hearings to rants about trivial matters, and contributed to his ultimate downfall.

What did McCarthy threaten to do in May of 1955?
Output: issue subpoenas to White House personnel

Input: Article: Through the use of multidimensional scaling, psychologists can map out similar emotional experiences, which allows a visual depiction of the "emotional distance" between experiences. A further step can be taken by looking at the map's dimensions of the emotional experiences. The emotional experiences are divided into two dimensions known as valence (how negative or positive the experience feels) and arousal (how energized or enervated the experience feels). These two dimensions can be depicted on a 2D coordinate map. This two-dimensional map was theorized to capture one important component of emotion called core affect. Core affect is not the only component to emotion, but gives the emotion its hedonic and felt energy.

Now answer this question: What do psychologists use to visually map emotional experiences?

Output: multidimensional scaling

Article: France started the Franco-Prussian War (187071), and was defeated by the Kingdom of Prussia and other German states. The end of the war led to the unification of Germany. Otto von Bismarck annexed Alsace and northern Lorraine to the new German Empire in 1871; unlike other members states of the German federation, which had governments of their own, the new Imperial territory of Alsace-Lorraine was under the sole authority of the Kaiser, administered directly by the imperial government in Berlin. Between 100,000 and 130,000 Alsatians (of a total population of about a million and a half) chose to remain French citizens and leave Reichsland Elsa-Lothringen, many of them resettling in French Algeria as Pieds-Noirs. Only in 1911 was Alsace-Lorraine granted some measure of autonomy, which was manifested also in a flag and an anthem (Elsassisches Fahnenlied). In 1913, however, the Saverne Affair (French: Incident de Saverne) showed the limits of this new tolerance of the Alsatian identity.

Question: The end of the war led to which companies unification?
Ans: Germany

Input: Super Nintendo Entertainment System
To compete with the popular Family Computer in Japan, NEC Home Electronics launched the PC Engine in 1987, and Sega Enterprises followed suit with the Mega Drive in 1988. The two platforms were later launched in North America in 1989 as the TurboGrafx-16 and the Genesis respectively. Both systems were built on 16-bit architectures and offered improved graphics and sound over the 8-bit NES. However, it took several years for Sega's system to become successful. Nintendo executives were in no rush to design a new system, but they reconsidered when they began to see their dominance in the market slipping.

What was NEC's competitor to the NES called in Japan?
Output:
PC Engine
