Yeah, I learned how to read inferior clocks, but.. I don't see the point.
So no, it's not that those students can't read a clock, they just can't read an analogue one, because they're probably need to as often as they need to read an octal clock, or a binary led clock, or a 24 hour dial clock, or Chinese..
Might be a design idea for future lawmakers.
In the end it reminds me of a quote by Edmund Burke: "Bad men obey the law only out of fear of punishment; good men obey it out of conscience - and thus good men are often restrained by it, while bad men find ways around it."
It's kind of sad to hear "adult" people claim in all seriousness that it's reasonable that a kernel alone spends more memory than the minimum requirement for running Windows 95, the operating system with kernel, drivers, a graphical user interface and even a few graphical user-space applications.
CD-RWs are somewhat wider in their stability, I have ~20 year old discs that are becoming unreadable because the actual foil is delaminating from the plastic disc. Meanwhile I have ~40 year old DS-DD floppies that are still fully readable even though their medium is in physical contact with the read/write heads (although here, again, storage conditions and especially the different brands/batches seem to make a difference).
