Question: Many of the U.S. Air Force's formal and informal traditions are an amalgamation of those taken from the Royal Air Force (e.g., dining-ins/mess nights) or the experiences of its predecessor organizations such as the U.S. Army Air Service, U.S. Army Air Corps and the U.S. Army Air Forces. Some of these traditions range from "Friday Name Tags" in flying units to an annual "Mustache Month." The use of "challenge coins" is a recent innovation that was adopted from the U.S. Army while another cultural tradition unique to the Air Force is the "roof stomp", practiced by Air Force members to welcome a new commander or to commemorate another event, such as a retirement.
Try to answer this question if possible: What organization did the US Air Force adopt "Challenge Coins" from?
Answer: U.S. Army
Question: If any boy produces an outstanding piece of work, it may be "Sent Up For Good", storing the effort in the College Archives for posterity. This award has been around since the 18th century. As Sending Up For Good is fairly infrequent, the process is rather mysterious to many of Eton's boys. First, the master wishing to Send Up For Good must gain the permission of the relevant Head of Department. Upon receiving his or her approval, the piece of work will be marked with Sent Up For Good and the student will receive a card to be signed by House Master, tutor and division master.
Try to answer this question if possible: When a student has work Sent Up For Good, who signs the card that they receive?
Answer: House Master, tutor and division master
Question: In the 2010s, American jurisdictions have experienced a shortage of lethal injection drugs, due to anti-death penalty advocacy and low production volume. Hospira, the only U.S. manufacturer of sodium thiopental, stopped making the drug in 2011. The European Union has outlawed the export of any product that could be used in an execution; this has prevented executioners from using EU-manufactured anesthetics like propofol which are needed for general medical purposes. Another alternative, pentobarbital, is also only manufactured in the European Union, which has caused the Danish producer to restrict distribution to U.S. government customers.
Try to answer this question if possible: What is the mission statement of the company that makes pentobarbital?
Answer: unanswerable
Question: Depleted uranium is also used as a shielding material in some containers used to store and transport radioactive materials. While the metal itself is radioactive, its high density makes it more effective than lead in halting radiation from strong sources such as radium. Other uses of depleted uranium include counterweights for aircraft control surfaces, as ballast for missile re-entry vehicles and as a shielding material. Due to its high density, this material is found in inertial guidance systems and in gyroscopic compasses. Depleted uranium is preferred over similarly dense metals due to its ability to be easily machined and cast as well as its relatively low cost. The main risk of exposure to depleted uranium is chemical poisoning by uranium oxide rather than radioactivity (uranium being only a weak alpha emitter).
Try to answer this question if possible: What type of alpha emitter is uranium?
Answer:
weak
