Problem: Symbiosis:

One of the most spectacular examples of obligate mutualism is between the siboglinid tube worms and symbiotic bacteria that live at hydrothermal vents and cold seeps. The worm has no digestive tract and is wholly reliant on its internal symbionts for nutrition. The bacteria oxidize either hydrogen sulfide or methane, which the host supplies to them. These worms were discovered in the late 1980s at the hydrothermal vents near the Galapagos Islands and have since been found at deep-sea hydrothermal vents and cold seeps in all of the world's oceans.

When were the symbiotic bacteria discovered?

A: unanswerable


Problem: Age of Enlightenment:

Coffeehouses represent a turning point in history during which people discovered that they could have enjoyable social lives within their communities. Coffeeshops became homes away from home for many who sought, for the first time, to engage in discourse with their neighbors and discuss intriguing and thought-provoking matters, especially those regarding philosophy to politics. Coffeehouses were essential to the Enlightenment, for they were centers of free-thinking and self-discovery. Although many coffeehouse patrons were scholars, a great deal were not. Coffeehouses attracted a diverse set of people, including not only the educated wealthy but also members of the bourgeoisie and the lower class. While it may seem positive that patrons, being doctors, lawyers, merchants, etc. represented almost all classes, the coffeeshop environment sparked fear in those who sought to preserve class distinction. One of the most popular critiques of the coffeehouse claimed that it "allowed promiscuous association among people from different rungs of the social ladder, from the artisan to the aristocrat" and was therefore compared to Noah's Ark, receiving all types of animals, clean or unclean. This unique culture served as a catalyst for journalism when Joseph Addison and Richard Steele recognized its potential as an audience. Together, Steele and Addison published The Spectator (1711), a daily publication which aimed, through fictional narrator Mr. Spectator, both to entertain and to provoke discussion regarding serious philosophical matters.

Which venue represents a turning point in history during which people discovered that they could have enjoyable social lives within their communities?

A: Coffeehouses


Problem: Capital punishment in the United States:

Opponents argue that the death penalty is not an effective means of deterring crime, risks the execution of the innocent, is unnecessarily barbaric in nature, cheapens human life, and puts a government on the same base moral level as those criminals involved in murder. Furthermore, some opponents argue that the arbitrariness with which it is administered and the systemic influence of racial, socio-economic, geographic, and gender bias on determinations of desert make the current practice of capital punishment immoral and illegitimate.

According to opponents of the death penalty, what does the death penalty cheapen?
---
A: human life


Problem: Israel:

Making up 16% of the population, Muslims constitute Israel's largest religious minority. About 2% of the population is Christian and 1.5% is Druze. The Christian population primarily comprises Arab Christians, but also includes post-Soviet immigrants, the foreign laborers of multinational origins, and followers of Messianic Judaism, considered by most Christians and Jews to be a form of Christianity. Members of many other religious groups, including Buddhists and Hindus, maintain a presence in Israel, albeit in small numbers. Out of more than one million immigrants from the former Soviet Union in Israel, about 300,000 are considered not Jewish by the Orthodox rabbinate.

Muslims make up how much of the Israel's population?

A:
16%
