Input: Pharmaceutical industry
By the 1890s the profound effect of adrenal extracts on many different tissue types had been discovered, setting off a search both for the mechanism of chemical signalling and efforts to exploit these observations for the development of new drugs. The blood pressure raising and vasoconstrictive effects of adrenal extracts were of particular interest to surgeons as hemostatic agents and as treatment for shock, and a number of companies developed products based on adrenal extracts containing varying purities of the active substance. In 1897 John Abel of Johns Hopkins University identified the active principle as epinephrine, which he isolated in an impure state as the sulfate salt. Industrial chemist Jokichi Takamine later developed a method for obtaining epinephrine in a pure state, and licensed the technology to Parke Davis. Parke Davis marketed epinephrine under the trade name Adrenalin. Injected epinephrine proved to be especially efficacious for the acute treatment of asthma attacks, and an inhaled version was sold in the United States until 2011 (Primatene Mist). By 1929 epinephrine had been formulated into an inhaler for use in the treatment of nasal congestion.

Who marketed epinephrine?
Output: Parke Davis

Input: Greeks
The Greeks of classical antiquity idealized their Mycenaean ancestors and the Mycenaean period as a glorious era of heroes, closeness of the gods and material wealth. The Homeric Epics (i.e. Iliad and Odyssey) were especially and generally accepted as part of the Greek past and it was not until the 19th century that scholars began to question Homer's historicity. As part of the Mycenaean heritage that survived, the names of the gods and goddesses of Mycenaean Greece (e.g. Zeus, Poseidon and Hades) became major figures of the Olympian Pantheon of later antiquity.

How did they believe their forebears lived ?
Output: Mycenaean period as a glorious era of heroes, closeness of the gods and material wealth

Input: 51st state
Several days after the referendum, the Resident Commissioner Pedro Pierluisi, Governor Luis Fortuno, and Governor-elect Alejandro Garcia Padilla wrote separate letters to the President of the United States Barack Obama addressing the results of the voting. Pierluisi urged Obama to begin legislation in favor of the statehood of Puerto Rico, in light of its win in the referendum. Fortuno urged him to move the process forward. Garcia Padilla asked him to reject the results because of their ambiguity. The White House stance related to the November 2012 plebiscite was that the results were clear, the people of Puerto Rico want the issue of status resolved, and a majority chose statehood in the second question. Former White House director of Hispanic media stated, "Now it is time for Congress to act and the administration will work with them on that effort, so that the people of Puerto Rico can determine their own future."

How did these politicians voice their concerns?
Output: wrote separate letters to the President of the United States Barack Obama

Input: Predation
Among predators there is a large degree of specialization. Many predators specialize in hunting only one species of prey. Others are more opportunistic and will kill and eat almost anything (examples: humans, leopards, dogs and alligators). The specialists are usually particularly well suited to capturing their preferred prey. The prey in turn, are often equally suited to escape that predator. This is called an evolutionary arms race and tends to keep the populations of both species in equilibrium. Some predators specialize in certain classes of prey, not just single species. Some will switch to other prey (with varying degrees of success) when the preferred target is extremely scarce, and they may also resort to scavenging or a herbivorous diet if possible.[citation needed]

What is the purpose of an evolutionary arms race?
Output:
keep the populations of both species in equilibrium
