Article: The first USAF dress uniform, in 1947, was dubbed and patented "Uxbridge Blue" after "Uxbridge 1683 Blue", developed at the former Bachman-Uxbridge Worsted Company. The current Service Dress Uniform, which was adopted in 1993 and standardized in 1995, consists of a three-button, pocketless coat, similar to that of a men's "sport jacket" (with silver "U.S." pins on the lapels, with a silver ring surrounding on those of enlisted members), matching trousers, and either a service cap or flight cap, all in Shade 1620, "Air Force Blue" (a darker purplish-blue). This is worn with a light blue shirt (Shade 1550) and Shade 1620 herringbone patterned necktie. Enlisted members wear sleeve insignia on both the jacket and shirt, while officers wear metal rank insignia pinned onto the coat, and Air Force Blue slide-on epaulet loops on the shirt. USAF personnel assigned to Base Honor Guard duties wear, for certain occasions, a modified version of the standard service dress uniform, but with silver trim on the sleeves and trousers, with the addition of a ceremonial belt (if necessary), wheel cap with silver trim and Hap Arnold Device, and a silver aiguillette placed on the left shoulder seam and all devices and accoutrement.

Question: Where does an officer in the USAF wear their rank insignia? 
Ans: pinned onto the coat


Article: Greek culture has evolved over thousands of years, with its beginning in the Mycenaean civilization, continuing through the Classical period, the Roman and Eastern Roman periods and was profoundly affected by Christianity, which it in turn influenced and shaped. Ottoman Greeks had to endure through several centuries of adversity that culminated in genocide in the 20th century but nevertheless included cultural exchanges and enriched both cultures. The Diafotismos is credited with revitalizing Greek culture and giving birth to the synthesis of ancient and medieval elements that characterize it today.

Question: What is considered the start of the Grecian cultural world ?
Ans: beginning in the Mycenaean civilization


Article: The 2000 U.S. Census in the write-in response category had a code listing which standardizes the placement of various write-in responses for automatic placement within the framework of the U.S. Census's enumerated races. Whereas most responses can be distinguished as falling into one of the five enumerated races, there remains some write-in responses which fall into the "Mixture" heading which cannot be racially categorized. These include "Bi Racial, Combination, Everything, Many, Mixed, Multi National, Multiple, Several and Various".

Question: What year did the US Census write in response category have a code-listing?
Ans: 2000


Article: In classical physics, an inertial reference frame is one in which an object that experiences no forces does not accelerate. In general relativity, an inertial frame of reference is one that is following a geodesic of space-time. An object that moves against a geodesic experiences a force. An object in free fall does not experience a force, because it is following a geodesic. An object standing on the earth, however, will experience a force, as it is being held against the geodesic by the surface of the planet. In light of this, the bucket of water rotating in empty space will experience a force because it rotates with respect to the geodesic. The water will become concave, not because it is rotating with respect to the distant stars, but because it is rotating with respect to the geodesic.

Question: What follows a geodesic of space-time?
Ans:
an inertial frame of reference
