This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

Input: Consider Input: Passage: In UTF-32 and UCS-4, one 32-bit code value serves as a fairly direct representation of any character's code point (although the endianness, which varies across different platforms, affects how the code value manifests as an octet sequence). In the other encodings, each code point may be represented by a variable number of code values. UTF-32 is widely used as an internal representation of text in programs (as opposed to stored or transmitted text), since every Unix operating system that uses the gcc compilers to generate software uses it as the standard "wide character" encoding. Some programming languages, such as Seed7, use UTF-32 as internal representation for strings and characters. Recent versions of the Python programming language (beginning with 2.2) may also be configured to use UTF-32 as the representation for Unicode strings, effectively disseminating such encoding in high-level coded software.

Output: What does not vary across platforms?


Input: Consider Input: Passage: The southern side of Miami includes Coral Way, The Roads and Coconut Grove. Coral Way is a historic residential neighborhood built in 1922 connecting Downtown with Coral Gables, and is home to many old homes and tree-lined streets. Coconut Grove was established in 1825 and is the location of Miami's City Hall in Dinner Key, the Coconut Grove Playhouse, CocoWalk, many nightclubs, bars, restaurants and bohemian shops, and as such, is very popular with local college students. It is a historic neighborhood with narrow, winding roads, and a heavy tree canopy. Coconut Grove has many parks and gardens such as Villa Vizcaya, The Kampong, The Barnacle Historic State Park, and is the home of the Coconut Grove Convention Center and numerous historic homes and estates.

Output: Along with Coconut Grove and Coral Way, what is notably unpresent in southern Miami?


Input: Consider Input: Passage: The developers of both Chrome and Firefox committed to developing Metro-style versions of their browsers; while Chrome's "Windows 8 mode" uses a full-screen version of the existing desktop interface, Firefox's version (which was first made available on the "Aurora" release channel in September 2013) uses a touch-optimized interface inspired by the Android version of Firefox. In October 2013, Chrome's app was changed to mimic the desktop environment used by Chrome OS. Development of the Firefox app for Windows 8 has since been cancelled, citing a lack of user adoption for the beta versions.


Output: Which three browsers promised to develop Metro-style versions of their browsers?
