Teacher: You will be given a passage, and your task is to generate a Yes/No question that is answerable based on the given passage.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Powdered sugar, also called confectioners' sugar, icing sugar, and icing cake, is a finely ground sugar produced by milling granulated sugar into a powdered state. It usually contains a small amount of anti-caking agent to prevent clumping and improve flow. Although most often produced in a factory, powdered sugar can also be made by processing ordinary granulated sugar in a coffee grinder, or by crushing it by hand in a mortar and pestle.
Solution: is confectionary sugar the same as powdered sugar?
Reason: The question is a yes/no question, and it is answerable based on the given passage.

Now, solve this instance: The Constitution does not directly mention secession. The legality of secession was hotly debated in the 19th century, with Southerners often claiming and Northerners generally denying that states have a legal right to unilaterally secede. The Supreme Court has consistently interpreted the Constitution to be an ``indestructible'' union. There is no legal basis a state can point to for unilaterally seceding. Many scholars hold that the Confederate secession was blatantly illegal. The Articles of Confederation explicitly state the Union is ``perpetual''; the U.S. Constitution declares itself an even ``more perfect union'' than the Articles of Confederation. Other scholars, while not necessarily disagreeing that the secession was illegal, point out that sovereignty is often de facto an ``extralegal'' question. Had the Confederacy won, any illegality of its actions under U.S. law would have been rendered irrelevant, just as the undisputed illegality of American rebellion under the British law of 1775 was rendered irrelevant. Thus, these scholars argue, the illegality of unilateral secession was not firmly de facto established until the Union won the Civil War; in this view, the legal question was resolved at Appomattox.
