Problem: Orthodox Judaism:

However, there is significant disagreement within Orthodox Judaism, particularly between Haredi Judaism and Modern Orthodox Judaism, about the extent and circumstances under which the proper application of Halakha should be re-examined as a result of changing realities. As a general rule, Haredi Jews believe that when at all possible the law should be maintained as it was understood by their authorities at the haskalah, believing that it had never changed. Modern Orthodox authorities are more willing to assume that under scrupulous examination, identical principles may lead to different applications in the context of modern life. To the Orthodox Jew, halakha is a guide, God's Law, governing the structure of daily life from the moment he or she wakes up to the moment he goes to sleep. It includes codes of behaviour applicable to a broad range of circumstances (and many hypothetical ones). There are though a number of halakhic meta-principles that guide the halakhic process and in an instance of opposition between a specific halakha and a meta-principle, the meta-principle often wins out . Examples of Halakhic Meta-Principles are: "Deracheha Darchei Noam" - the ways of Torah are pleasant, "Kavod Habriyot" - basic respect for human beings, "Pikuach Nefesh" - the sanctity of human life.

Problem: Ethnohistory is the study of ethnographic cultures and indigenous customs by examining historical records. It is also the study of the history of various ethnic groups that may or may not exist today. Ethnohistory uses both historical and ethnographic data as its foundation. Its historical methods and materials go beyond the standard use of documents and manuscripts. Practitioners recognize the utility of such source material as maps, music, paintings, photography, folklore, oral tradition, site exploration, archaeological materials, museum collections, enduring customs, language, and place names.
What does ethnohistory use both historical and ethnographic data as?

Answer: its foundation

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
One wave of the population boom ended abruptly in the mid-1980s, as oil prices fell precipitously. The space industry also suffered in 1986 after the Space Shuttle Challenger disintegrated shortly after launch. There was a cutback in some activities for a period. In the late 1980s, the city's economy suffered from the nationwide recession. After the early 1990s recession, Houston made efforts to diversify its economy by focusing on aerospace and health care/biotechnology, and reduced its dependence on the petroleum industry. Since the increase of oil prices in the 2000s, the petroleum industry has again increased its share of the local economy.
In what year did the space shuttle Challenger succeed after launch?
A: unanswerable

Context and question: In an ecosystem, predation is a biological interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked). Predators may or may not kill their prey prior to feeding on them, but the act of predation often results in the death of the prey and the eventual absorption of the prey's tissue through consumption. Thus predation is often, though not always, carnivory. Other categories of consumption are herbivory (eating parts of plants), fungivory (eating parts of fungi), and detritivory (the consumption of dead organic material (detritus)). All these consumption categories fall under the rubric of consumer-resource systems. It can often be difficult to separate various types of feeding behaviors. For example, some parasitic species prey on a host organism and then lay their eggs on it for their offspring to feed on it while it continues to live in or on its decaying corpse after it has died. The key characteristic of predation however is the predator's direct impact on the prey population. On the other hand, detritivores simply eat dead organic material arising from the decay of dead individuals and have no direct impact on the "donor" organism(s).
What does an herbivore eat?
Answer: plants
