Input: Read this: The Reinvent the Toilet Challenge is a long-term research and development effort to develop a hygienic, stand-alone toilet. This challenge is being complemented by another investment program to develop new technologies for improved pit latrine emptying (called by the foundation the "Omni-Ingestor") and fecal sludge processing (called "Omni-Processor"). The aim of the "Omni Processor" is to convert excreta (for example fecal sludge) into beneficial products such as energy and soil nutrients with the potential to develop local business and revenue.
Question: What does another investment program use to convert sludge?

Output: unanswerable

QUES: Yale is organized into fourteen constituent schools: the original undergraduate college, the Yale Graduate School of Arts and Sciences, and twelve professional schools.

Maria Deraismes was initiated into Freemasonry in 1882, then resigned to allow her lodge to rejoin their Grand Lodge. Having failed to achieve acceptance from any masonic governing body, she and Georges Martin started a mixed masonic lodge that actually worked masonic ritual. Annie Besant spread the phenomenon to the English speaking world. Disagreements over ritual led to the formation of exclusively female bodies of Freemasons in England, which spread to other countries. Meanwhile, the French had re-invented Adoption as an all-female lodge in 1901, only to cast it aside again in 1935. The lodges, however, continued to meet, which gave rise, in 1959, to a body of women practising continental Freemasonry.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why did Deraismes dislike Freemasonry?
Ah, so.. unanswerable

Question: In addition to numerous articles on mathematics, Whitehead wrote three major books on the subject: A Treatise on Universal Algebra (1898), Principia Mathematica (co-written with Bertrand Russell and published in three volumes between 1910 and 1913), and An Introduction to Mathematics (1911). The former two books were aimed exclusively at professional mathematicians, while the latter book was intended for a larger audience, covering the history of mathematics and its philosophical foundations. Principia Mathematica in particular is regarded as one of the most important works in mathematical logic of the 20th century.
Try to answer this question if possible: With what mathematician and philosopher did Whitehead collaborate to write Principia Mathematica?
Answer: Bertrand Russell

Problem: Each republican magistrate held certain constitutional powers. Only the People of Rome (both plebeians and patricians) had the right to confer these powers on any individual magistrate. The most powerful constitutional power was imperium. Imperium was held by both consuls and praetors. Imperium gave a magistrate the authority to command a military force. All magistrates also had the power of coercion. This was used by magistrates to maintain public order. While in Rome, all citizens had a judgement against coercion. This protection was called provocatio (see below). Magistrates also had both the power and the duty to look for omens. This power would often be used to obstruct political opponents.
Who had the right to grant powers to a magistrate?
---
Answer:
People of Rome
