Q: In this task, you are given a set of context paragraphs, some supporting facts and an answer of a question. Your task is to generate question for given answer based on set of context paragraphs, supporting facts and an answer.
Context_1 : It was originally developed in the 1936 for use by the Luftwaffe, but was not adopted at that time. In the 1972-1973 time frame, Walther introduced the Walther PP Super chambered in the cartridge for the West German Police. The Walther PP Super was discontinued in 1979. The cartridge was made available to the civilian market in 1975. Context_2 : Windows Mobile is a mobile operating system developed by Microsoft, based on Windows CE and is the successor to Pocket PC 2002 and predecessor of Windows Phone. New devices running Windows Mobile were released between 2003 and 2010. Many different companies produced devices running Windows Mobile during this time frame. The table below groups devices into two categories, those with cellular capability and those without. The version of Windows Mobile 5.x called "Smartphone", and the version of Windows Mobile 6.x called "Standard", is designed to run on devices without a touch screen; all other devices listed have touch screens. Context_3 : The "Panzerkampfwagen" IV (PzKpfw IV), commonly known as the Panzer IV, was a German medium tank developed in the late 1930s and used extensively during the Second World War. Its ordnance inventory designation was Sd.Kfz. 161. Context_4 : The Schmalturm turret was a tank turret designed for use on the Panzer V Ausf. B Panther II medium tank, Panther A and G medium tank, Panzer IV Ausf. J medium tank and the VK 30.02 DB (a medium tank prototype). The turret's shape resembled the Soviet T-34 tank turret. It featured a narrow front to maximize protection while minimizing weight. It was both lighter and easier-to-manufacture than the standard Panther turret. The turret had a stereoscopic rangefinder with lenses on either side of the turret, located in spherical bulges. No Schmalturms entered series production. Context_5 : Several motivations underlie the project. The primary ambition of MOM is to preserve an image of our era, created by numerous participants all over the planet. MOM will also contain information which our society is obliged to forward to the future: e.g. description of nuclear waste repositories. MOM collaborates with the NEA and SKB. Although the most obvious ambition and often described in the media is the concern about preserving our knowledge, this is not the primary goal of MOM. Serving as a time capsule MOM is both: in a time frame of millennia it is the story about us, and in a time frame of decades it is a backup. In times where global warming, nuclear danger and biological warfare threaten the existence of civilization, saving the core knowledge and culture acquired over centuries is a backup measure. In case of a collapse, the MOM project could help survivors to rebuild civilization. Linked to this, an another reason is of political order: facing the lack of reactivity of authorities concerning global warming, the MOM project is a reminder of what can happen. Roman and Greek civilizations whose histories have been reconstructed by the small percentage of texts and artifacts which survived until our days are examples that have inspired the MOM project. Finally, it's a critic of our digital civilization : according to Kunze, maybe nothing of the 21st century will last in the future, since most of our interactions are now virtual. The "accuracy versus bullshit" is one of the main themes of the MOM project, worried about loss of information, the project can only aim to save a fragment of the information produced until today, but this fragment has to be representative. Context_6 : The quantum jump method, also known as the Monte Carlo wave function (MCWF) method, is a technique in computational physics used for simulating open quantum systems. The quantum jump method was developed by Dalibard, Castin and Mlmer, with a very similar method also developed by Carmichael in the same time frame. Other contemporaneous works on wave-function-based Monte Carlo approaches to open quantum systems include those of Dum, Zoller and Ritsch and Hegerfeldt and Wilser. Context_7 : A rapid reaction force is a military or police unit designed to respond in very short time frames to emergencies. When used in reference to police forces such as SWAT teams, the time frame is minutes, while in military applications, such as with the use of paratroops or other commandos, the time frame is hours to days. Context_8 : Rapid Results is a structured process that mobilizes teams to achieve tangible results over a rapid time frame and accelerate organizational learning. Schaffer Consulting, a management consulting firm headquartered in Stamford, Connecticut, developed the Rapid Results approach based on their experience working with clients across industries to achieve breakthrough levels of performance. The approach and its practitioners have since been recognized in "The New York Times", "Harvard Business Review", and "Foreign Policy", among other publications. In 2007, Schaffer Consulting founded the Rapid Results Institute (RRI) to refine the methodology to support non-profit work and development projects across Sub-Saharan Africa, South America, the United States, and the Middle East. Context_9 : Pre-conception counseling (also called pre-conceptual counseling) is a meeting with a health-care professional (generally a physician or midwife) by a woman "before" attempting to become pregnant. It generally includes a pre-conception risk assessment for any potential complications of pregnancy as well as modifications of risk factors, such as increasing folic acid intake to reduce the risk of neural tube defects and counseling on smoking cessation, alcohol reduction, and medications that may compromise fetal development. Physicians, midwives and baby experts recommend that a woman visit them as soon as the woman is contemplating having a child, and optimally around 3 to 6 months before actual attempts are made to conceive. This time frame allows a woman to better prepare her body for successful conception (fertilization) and pregnancy, and allows her to reduce any health risks which are within her control. Agencies such as the March of Dimes have developed screening tools that healthcare providers can use with their patients. In addition, obstetricians or midwives (see Obstetrics, Midwifery, General Practitioner) have developed comprehensive check-lists and assessments for the woman who is planning to become pregnant. Context_10 : The Ambrosian Iliad or Ilias Picta (Milan, Biblioteca Ambrosiana, Cod. F. 205 Inf.) is a 5th-century illuminated manuscript on vellum of the "Iliad" of Homer. It is thought to have been produced in Constantinople during the late 5th or early 6th century AD, specifically between 493 and 508. This time frame was developed by Ranuccio Bandinelli and is based on the abundance of green in the pictures, which happened to be the color of the faction in power at the time. It has since been reduced to a series of miniatures cut out of the manuscript. It is one of the oldest surviving illustrated manuscripts. In addition, it is the only surviving portion of an illustrated copy of Homer from antiquity and, along with the Vergilius Vaticanus and the Vergilius Romanus, one of only three illustrated manuscripts of classical literature to survive from antiquity. fact_1 : B Panther II medium tank, Panther A and G medium tank, Panzer IV Ausf. fact_2 : The "Panzerkampfwagen" IV (PzKpfw IV), commonly known as the Panzer IV, was a German medium tank developed in the late 1930s and used extensively during the Second World War. Answer: late 1930s
A:
Schmalturm was based on the tank that was developed in what time frame?
