I think A is spot on, B just confuses the rules.

Totally agree, public variables do get a getter function automatically.

Wait, private functions can’t be called by derived contracts? That’s surprising!

I disagree, B is misleading about private functions.

A is correct about internal and private functions!

Okay, I think I've got this. I'll select option A to register the devices and sign the app. That seems like the most straightforward solution.

Hmm, I'm a bit unsure about the difference between syncing non-recurring events and syncing recurring events. I'll need to read through the options carefully.

I recall discussing how incentivizing challenging the status quo can lead to risky behaviors in our case studies. So maybe B is right, but D could fit too.

Hmm, I'm not sure about this. I'll have to review the networking concepts again.
