The stemmatic method's final step is emendatio, also sometimes referred to as "conjectural emendation." But in fact, the critic employs conjecture at every step of the process. Some of the method's rules that are designed to reduce the exercise of editorial judgment do not necessarily produce the correct result. For example, where there are more than two witnesses at the same level of the tree, normally the critic will select the dominant reading. However, it may be no more than fortuitous that more witnesses have survived that present a particular reading. A plausible reading that occurs less often may, nevertheless, be the correct one.
A reading that occurs left often is always considered what?
A: unanswerable

In January 2009, the Green Power Partnership (GPP, sponsored by the EPA) listed Northwestern as one of the top 10 universities in the country in purchasing energy from renewable sources. The university matches 74 million kilowatt hours (kWh) of its annual energy use with Green-e Certified Renewable Energy Certificates (RECs). This green power commitment represents 30 percent of the university's total annual electricity use and places Northwestern in the EPA's Green Power Leadership Club. The 2010 Report by The Sustainable Endowments Institute awarded Northwestern a "B-" on its College Sustainability Report Card. The Initiative for Sustainability and Energy at Northwestern (ISEN), supporting research, teaching and outreach in these themes, was launched in 2008.
How much of the university's total annual electric bill is represented by the red power commitment?
A: unanswerable

Contemporary humanism entails a qualified optimism about the capacity of people, but it does not involve believing that human nature is purely good or that all people can live up to the Humanist ideals without help. If anything, there is recognition that living up to one's potential is hard work and requires the help of others. The ultimate goal is human flourishing; making life better for all humans, and as the most conscious species, also promoting concern for the welfare of other sentient beings and the planet as a whole. The focus is on doing good and living well in the here and now, and leaving the world a better place for those who come after. In 1925, the English mathematician and philosopher Alfred North Whitehead cautioned: "The prophecy of Francis Bacon has now been fulfilled; and man, who at times dreamt of himself as a little lower than the angels, has submitted to become the servant and the minister of nature. It still remains to be seen whether the same actor can play both parts".
What is human flourishing against?

unanswerable
