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: Newton's Second Law asserts the direct proportionality of acceleration to force and the inverse proportionality of acceleration to mass. Accelerations can be defined through kinematic measurements. However, while kinematics are well-described through reference frame analysis in advanced physics, there are still deep questions that remain as to what is the proper definition of mass. General relativity offers an equivalence between space-time and mass, but lacking a coherent theory of quantum gravity, it is unclear as to how or whether this connection is relevant on microscales. With some justification, Newton's second law can be taken as a quantitative definition of mass by writing the law as an equality; the relative units of force and mass then are fixed.
[A]: Newton's Third Law asserts the direct proportionality of acceleration to what?

[A]: What kind of institution isn't KU's School of Business?

[Q]: Passage: The gastronomic symbol of the region is undoubtedly the Choucroute, a local variety of Sauerkraut. The word Sauerkraut in Alsatian has the form surkrut, same as in other southwestern German dialects, and means "sour cabbage" as its Standard German equivalent. This word was included into the French language as choucroute. To make it, the cabbage is finely shredded, layered with salt and juniper and left to ferment in wooden barrels. Sauerkraut can be served with poultry, pork, sausage or even fish. Traditionally it is served with Strasbourg sausage or frankfurters, bacon, smoked pork or smoked Morteau or Montbeliard sausages, or a selection of other pork products. Served alongside are often roasted or steamed potatoes or dumplings.
[A]:
What word does Choucroute come from?
