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.

[Q]: Passage: Extension causes the rock units as a whole to become longer and thinner. This is primarily accomplished through normal faulting and through the ductile stretching and thinning. Normal faults drop rock units that are higher below those that are lower. This typically results in younger units being placed below older units. Stretching of units can result in their thinning; in fact, there is a location within the Maria Fold and Thrust Belt in which the entire sedimentary sequence of the Grand Canyon can be seen over a length of less than a meter. Rocks at the depth to be ductilely stretched are often also metamorphosed. These stretched rocks can also pinch into lenses, known as boudins, after the French word for "sausage", because of their visual similarity.
[A]: What is another word for thinning rocks in French?


[Q]: Passage: The Standard Model groups matter particles into three generations, where each generation consists of two quarks and two leptons. The first generation is the up and down quarks, the electron and the electron neutrino; the second includes the charm and strange quarks, the muon and the muon neutrino; the third generation consists of the top and bottom quarks and the tau and tau neutrino. The most natural explanation for this would be that quarks and leptons of higher generations are excited states of the first generations. If this turns out to be the case, it would imply that quarks and leptons are composite particles, rather than elementary particles.
[A]: What model has two generations?


[Q]: Passage: On one hand, this means that the Belgian political landscape, generally speaking, consists of only two components: the Dutch-speaking population represented by Dutch-language political parties, and the majority populations of Wallonia and Brussels, represented by their French-speaking parties. The Brussels region emerges as a third component. This specific dual form of federalism, with the special position of Brussels, consequently has a number of political issues—even minor ones—that are being fought out over the Dutch/French-language political division. With such issues, a final decision is possible only in the form of a compromise. This tendency gives this dual federalism model a number of traits that generally are ascribed to confederalism, and makes the future of Belgian federalism contentious.
[A]:
How many components does the Belgian political landscape exclude?
