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.

Passage: Turner Classic Movies essentially operates as a commercial-free service, with the only advertisements on the network being shown between features – which advertise TCM products, network promotions for upcoming special programs and the original trailers for films that are scheduled to be broadcast on TCM (particularly those that will air during the primetime hours), and featurettes about classic film actors and actresses. In addition to this, extended breaks between features are filled with theatrically released movie trailers and classic short subjects – from series such as The Passing Parade, Crime Does Not Pay, Pete Smith Specialties, and Robert Benchley – under the banner name TCM Extras (formerly One Reel Wonders). In 2007, some of the short films featured on TCM were made available for streaming on TCM's website. Partly to allow these interstitials, Turner Classic Movies schedules its feature films either at the top of the hour or at :15, :30 or :45 minutes past the hour, instead of in timeslots of varying five-minute increments.
What were TCM products previously known as?

Passage: Code points in the range U+D800–U+DBFF (1,024 code points) are known as high-surrogate code points, and code points in the range U+DC00–U+DFFF (1,024 code points) are known as low-surrogate code points. A high-surrogate code point (also known as a leading surrogate) followed by a low-surrogate code point (also known as a trailing surrogate) together form a surrogate pair used in UTF-16 to represent 1,048,576 code points outside BMP. High and low surrogate code points are not valid by themselves. Thus the range of code points that are available for use as characters is U+0000–U+D7FF and U+E000–U+10FFFF (1,112,064 code points). The value of these code points (i.e., excluding surrogates) is sometimes referred to as the character's scalar value.
What is a low-surrogate followed by a high-surrogate called?

Passage: In the controversial elections in 2002, Sassou won with almost 90% of the vote cast. His two main rivals, Lissouba and Bernard Kolelas, were prevented from competing and the only remaining credible rival, Andre Milongo, advised his supporters to boycott the elections and then withdrew from the race. A new constitution, agreed upon by referendum in January 2002, granted the president new powers, extended his term to seven years, and introduced a new bicameral assembly. International observers took issue with the organization of the presidential election and the constitutional referendum, both of which were reminiscent in their organization of Congo's era of the one-party state. Following the presidential elections, fighting restarted in the Pool region between government forces and rebels led by Pastor Ntumi; a peace treaty to end the conflict was signed in April 2003.

Who won more than 90% of the vote?
