Problem: Animal:

Several animal phyla are recognized for their lack of bilateral symmetry, and are thought to have diverged from other animals early in evolution. Among these, the sponges (Porifera) were long thought to have diverged first, representing the oldest animal phylum. They lack the complex organization found in most other phyla. Their cells are differentiated, but in most cases not organized into distinct tissues. Sponges typically feed by drawing in water through pores. However, a series of phylogenomic studies from 2008-2015 have found support for Ctenophora, or comb jellies, as the basal lineage of animals. This result has been controversial, since it would imply that that sponges may not be so primitive, but may instead be secondarily simplified. Other researchers have argued that the placement of Ctenophora as the earliest-diverging animal phylum is a statistical anomaly caused by the high rate of evolution in ctenophore genomes.

Which animal represents the oldest animal phyla?
---
A: sponges


Problem: For a period ending in the mid-20th century, long-serving cardinal priests were entitled to fill vacancies that arose among the cardinal bishops, just as cardinal deacons of ten years' standing are still entitled to become cardinal priests. Since then, cardinals have been advanced to cardinal bishop exclusively by papal appointment.
How have cardinals been advance to cardinal priests?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Unlike those of Mexican states' schools, curricula of Mexico City's public schools is managed by the federal Secretary of Public Education. The whole funding is allocated by the government of Mexico City (in some specific cases, such as El Colegio de México, funding comes from both the city's government and other public and private national and international entities).[citation needed] The city's public high school system is the Instituto de Educación Media Superior del Distrito Federal (IEMS-DF).
Who is in charge of the education in Mexico City?
A: Secretary of Public Education


Context and question: In recent years the city government, under Mayor Manny Diaz, has taken an ambitious stance in support of bicycling in Miami for both recreation and commuting. Every month, the city hosts "Bike Miami", where major streets in Downtown and Brickell are closed to automobiles, but left open for pedestrians and bicyclists. The event began in November 2008, and has doubled in popularity from 1,500 participants to about 3,000 in the October 2009 Bike Miami. This is the longest-running such event in the US. In October 2009, the city also approved an extensive 20-year plan for bike routes and paths around the city. The city has begun construction of bike routes as of late 2009, and ordinances requiring bike parking in all future construction in the city became mandatory as of October 2009.
In what month in 2018 did Bike Miami start?
Answer: unanswerable


Question: At Princeton, the physicist Robert R. Wilson encouraged Feynman to participate in the Manhattan Project—the wartime U.S. Army project at Los Alamos developing the atomic bomb. Feynman said he was persuaded to join this effort to build it before Nazi Germany developed their own bomb. He was assigned to Hans Bethe's theoretical division and impressed Bethe enough to be made a group leader. He and Bethe developed the Bethe–Feynman formula for calculating the yield of a fission bomb, which built upon previous work by Robert Serber.
Is there an answer to this question: What was the purpose of the Bethe-Feynman formula?

Answer: calculating the yield of a fission bomb


Whitehead's most complete work on education is the 1929 book The Aims of Education and Other Essays, which collected numerous essays and addresses by Whitehead on the subject published between 1912 and 1927. The essay from which Aims of Education derived its name was delivered as an address in 1916 when Whitehead was president of the London Branch of the Mathematical Association. In it, he cautioned against the teaching of what he called "inert ideas" – ideas that are disconnected scraps of information, with no application to real life or culture. He opined that "education with inert ideas is not only useless: it is, above all things, harmful."
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When was "The Aims of Education and Other Essays" published?
Ah, so..
1929
