The problem: Answer a question about this article:
A commutated DC motor has a set of rotating windings wound on an armature mounted on a rotating shaft. The shaft also carries the commutator, a long-lasting rotary electrical switch that periodically reverses the flow of current in the rotor windings as the shaft rotates. Thus, every brushed DC motor has AC flowing through its rotating windings. Current flows through one or more pairs of brushes that bear on the commutator; the brushes connect an external source of electric power to the rotating armature.
What type of current is featured in brushed DC motors?
****
The answer: AC

The problem: Answer a question about this article:
The opinion of the majority of Croatian linguists[citation needed] is that there has never been a Serbo-Croatian language, but two different standard languages that overlapped sometime in the course of history. However, Croatian linguist Snjezana Kordic has been leading an academic discussion on that issue in the Croatian journal Knjizevna republika from 2001 to 2010. In the discussion, she shows that linguistic criteria such as mutual intelligibility, huge overlap in linguistic system, and the same dialectic basis of standard language provide evidence that Croatian, Serbian, Bosnian and Montenegrin are four national variants of the pluricentric Serbo-Croatian language. Igor Mandic states: "During the last ten years, it has been the longest, the most serious and most acrid discussion () in 21st-century Croatian culture". Inspired by that discussion, a monograph on language and nationalism has been published.
Who stated that the argument between pluricentric or dual standard classifications has been the "longest, most serious, and most acrid discussion in 21st century Croatian culture?"
****
The answer: Igor Mandic
