Question: The first Archivist, R.D.W. Connor, began serving in 1934, when the National Archives was established by Congress. As a result of a first Hoover Commission recommendation, in 1949 the National Archives was placed within the newly formed General Services Administration (GSA). The Archivist served as a subordinate official to the GSA Administrator until the National Archives and Records Administration became an independent agency on April 1, 1985.
Is there an answer to this question: In what year did Hoover become President?

Answer: unanswerable


Question: The majority of Freemasonry considers the Liberal (Continental) strand to be Irregular, and thus withhold recognition. For the Continental lodges, however, having a different approach to Freemasonry was not a reason for severing masonic ties. In 1961, an umbrella organisation, Centre de Liaison et d'Information des Puissances maçonniques Signataires de l'Appel de Strasbourg (CLIPSAS) was set up, which today provides a forum for most of these Grand Lodges and Grand Orients worldwide. Included in the list of over 70 Grand Lodges and Grand Orients are representatives of all three of the above categories, including mixed and women's organisations. The United Grand Lodge of England does not communicate with any of these jurisdictions, and expects its allies to follow suit. This creates the distinction between Anglo-American and Continental Freemasonry.
Is there an answer to this question: How many Grand Lodges and Grand Orients are unlisted in the CLIPSAS list?

Answer: unanswerable


Question: All the objects from everyday life that we can bump into, touch or squeeze are composed of atoms. This atomic matter is in turn made up of interacting subatomic particles—usually a nucleus of protons and neutrons, and a cloud of orbiting electrons. Typically, science considers these composite particles matter because they have both rest mass and volume. By contrast, massless particles, such as photons, are not considered matter, because they have neither rest mass nor volume. However, not all particles with rest mass have a classical volume, since fundamental particles such as quarks and leptons (sometimes equated with matter) are considered "point particles" with no effective size or volume. Nevertheless, quarks and leptons together make up "ordinary matter", and their interactions contribute to the effective volume of the composite particles that make up ordinary matter.
Is there an answer to this question: What cannot contribute to effective volume?

Answer: unanswerable


Question: The Devonian spanned roughly from 419 to 359 Ma. The period was a time of great tectonic activity, as Laurasia and Gondwana drew closer together. The continent Euramerica (or Laurussia) was created in the early Devonian by the collision of Laurentia and Baltica, which rotated into the natural dry zone along the Tropic of Capricorn. In these near-deserts, the Old Red Sandstone sedimentary beds formed, made red by the oxidized iron (hematite) characteristic of drought conditions. Near the equator Pangaea began to consolidate from the plates containing North America and Europe, further raising the northern Appalachian Mountains and forming the Caledonian Mountains in Great Britain and Scandinavia. The southern continents remained tied together in the supercontinent of Gondwana. The remainder of modern Eurasia lay in the Northern Hemisphere. Sea levels were high worldwide, and much of the land lay submerged under shallow seas. The deep, enormous Panthalassa (the "universal ocean") covered the rest of the planet. Other minor oceans were Paleo-Tethys, Proto-Tethys, Rheic Ocean and Ural Ocean (which was closed during the collision with Siberia and Baltica).
Is there an answer to this question: During what time period was the Devonian era?

Answer:
419 to 359 Ma.
