Question: Dell previously had its headquarters in the Arboretum complex in northern Austin, Texas. In 1989 Dell occupied 127,000 square feet (11,800 m2) in the Arboretum complex. In 1990, Dell had 1,200 employees in its headquarters. In 1993, Dell submitted a document to Round Rock officials, titled "Dell Computer Corporate Headquarters, Round Rock, Texas, May 1993 Schematic Design." Despite the filing, during that year the company said that it was not going to move its headquarters. In 1994, Dell announced that it was moving most of its employees out of the Arboretum, but that it was going to continue to occupy the top floor of the Arboretum and that the company's official headquarters address would continue to be the Arboretum. The top floor continued to hold Dell's board room, demonstration center, and visitor meeting room. Less than one month prior to August 29, 1994, Dell moved 1,100 customer support and telephone sales employees to Round Rock. Dell's lease in the Arboretum had been scheduled to expire in 1994.
Is there an answer to this question: What Texas city was Dell's headquarters previously in?

Answer: Austin

Question: On 14 June 1940, the German army marched into Paris, which had been declared an "open city". On 1617 July 1942, following German orders, the French police and gendarmes arrested 12,884 Jews, including 4,115 children, and confined them during five days at the Vel d'Hiv (Velodrome d'Hiver), from which they were transported by train to the extermination camp at Auschwitz. None of the children came back. On 25 August 1944, the city was liberated by the French 2nd Armoured Division and the 4th Infantry Division of the United States Army. General Charles de Gaulle led a huge and emotional crowd down the Champs Elysees towards Notre Dame de Paris, and made a rousing speech from the Hotel de Ville.
Is there an answer to this question: On what date did the German army declare Paris as an open city?

Answer: 14 June 1940

Question: Officers may be commissioned upon graduation from the United States Air Force Academy, upon graduation from another college or university through the Air Force Reserve Officer Training Corps (AFROTC) program, or through the Air Force Officer Training School (OTS). OTS, previously located at Lackland AFB, Texas until 1993 and located at Maxwell Air Force Base in Montgomery, Alabama since 1993, in turn encompasses two separate commissioning programs: Basic Officer Training (BOT), which is for line-officer candidates of the active-duty Air Force and the U.S. Air Force Reserve; and the Academy of Military Science (AMS), which is for line-officer candidates of the Air National Guard. (The term "line officer" derives from the concept of the line of battle and refers to an officer whose role falls somewhere within the "Line of the Air", meaning combat or combat-support operations within the scope of legitimate combatants as defined by the Geneva Conventions.)
Is there an answer to this question: USAF Officers can be commissioned after graduation from what school?

Answer: United States Air Force Academy

Question: However, the lifecycles of most living polychaetes, which are almost all marine animals, are unknown, and only about 25% of the 300+ species whose lifecycles are known follow this pattern. About 14% use a similar external fertilization but produce yolk-rich eggs, which reduce the time the larva needs to spend among the plankton, or eggs from which miniature adults emerge rather than larvae. The rest care for the fertilized eggs until they hatch some by producing jelly-covered masses of eggs which they tend, some by attaching the eggs to their bodies and a few species by keeping the eggs within their bodies until they hatch. These species use a variety of methods for sperm transfer; for example, in some the females collect sperm released into the water, while in others the males have a penis that inject sperm into the female. There is no guarantee that this is a representative sample of polychaetes' reproductive patterns, and it simply reflects scientists' current knowledge.
Is there an answer to this question: How many species of polychaetes have known lifecycles?

Answer:
about 25%
