instruction:
Compose a new way to ask the same question. The new question must be asking the exact same thing as the original question does. Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.
question:
original question: What is the disease cause of [Rubella]?
answer: rubella virus
answer type: Disease cause.
auxiliary information: Rubella, also known as German measles or three-day measles, is an infection caused by the rubella virus. This disease is often mild with half of people not realizing that they are sick. A rash may start around two weeks after exposure and last for three days. It usually starts on the face and spreads to the rest of the body. The rash is not as bright as that of measles and is sometimes itchy. Swollen lymph nodes are common and may last a few weeks. A fever, sore throat, and fatigue may also occur. In adults joint pain is common. Complications may include bleeding problems, testicular swelling, and inflammation of nerves. Infection during early pregnancy may result in a child born with congenital rubella syndrome or miscarriage. Symptoms of CRS include problems with the eyes such as cataracts, ears such as deafness, heart, and brain. Problems are rare after the 20th week of pregnancy. Rubella is usually spread through the air via coughs of people who are infected. People are infectious during the week before and after the appearance of the rash. Babies with CRS may spread the virus for more than a year. Only humans are infected. Insects do not spread the disease.
answer:
[Rubella] is the cause of what disease?


question:
original question: What other inventions are associated with the same patent as [A simple method to form crystalline compound semiconductors on silicon substrates] is?
answer: liquid-phase epitaxy on si substrate
answer type: Invention.
auxiliary information: Researchers in Dr. Jim Plummer's laboratory at Stanford University have developed a simple new method to fabricate high mobility channel materials on silicon devices.  This low-cost, CMOS-compatible process is based on a liquid phase epitaxy technique where material contacts a seed window in the bulk silicon from which high quality single crystal growth propagates. State of the art Germanium on Insulator (GeOI) devices have been fabricated and the method has been demonstrated for GaAs on oxide and can be applied to a variety of compound semiconductors, such as GaP, InP, InSb and GaSb etc., that melt congruently.  The technology could be used to easily fabricate a variety of structures, including fins, ultra-thin body, and nanowire devices.The basic patented process and its applications to GeOI is included in Stanford Docket 03-201 (U.S. Patent No. 7,498,243).  Further work with compound semiconductors is described in a pending continuation-in-part patent application included in Stanford Docket S08-404.Status of Research  The inventors have demonstrated state of the art GeOI devices and surprisingly high quality crystalline GaAs on insulator on bulk Si substrates using this technique.

What are the other inventions that are associated with the same patent as [A simple method to form crystalline compound semiconductors on silicon substrates] is?


question:
original question: How many video game distribution system does [Microsoft Windows] support?
answer: 4
answer type: Video Game Distribution System.
auxiliary information: Microsoft Windows is a metafamily of graphical operating systems developed, marketed, and sold by Microsoft. It consists of several families of operating systems, each of which cater to a certain sector of the computing industry. Active Windows families include Windows NT, Windows Embedded and Windows Phone; these may encompass subfamilies, e.g. Windows Embedded Compact or Windows Server. Defunct Windows families include Windows 9x and Windows Mobile. Microsoft introduced an operating environment named Windows on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces. Microsoft Windows came to dominate the world's personal computer market with over 90% market share, overtaking Mac OS, which had been introduced in 1984. However, since 2012, it sells less than Android, which became the most popular operating system in 2014, when counting all of the computing platforms Windows runs on; in 2014, the number of Windows device sold were less than 25% of Android devices sold. As of July 2015, the most recent version of Windows for personal computers, tablets and smartphones is Windows 10.
answer:

What is the quantity of video game distribution systems that [Microsoft Windows] supports?
