Not really wrong, but on reading it is easy to fake. Usually just retelling in some form what the teacher said will do the trick. (That approach also works later in life, unfortunately...) On a math question, if you do not understand it, you do not get the result in most cases.

Now, actual reading comprehension where you have to give an informed and insightful analysis and then takle a position and justify that rationally. Yes. But from my experience, you need an exceptional teacher for that to happen in school.

You just do not know yet that you _will_ give up vegetarianism! They already know.

Even regular, European-style anti-trust action done half would have nicely worked. The problem is not the methods. The problem is nothing was done when the need for action was absolutely obvious.

Oh, I am sure _you_ do not do these. Competent people do backups or redundant copies for anything that is critical, regardless of time-frame.

I know a few mathematicians. None of them are stupid. All of them can do risk management to a reasonable degree. These people from the stroy must be the dross.

Yes. And that case is covered in all _basic_ BCM materials. You do not only need backup for data. You also need backups for roles.

Well, either you can trust people to not lose their keys, or you cannot. In the second case, you need some redundancy. But sure, the screw-up also included them apparently trusting incompetents too much.

Indeed. Probably some more big-ego-small-skill people managed to make it in there.

Sad but true.

Indeed.

If you have a working market, product quality matters. The while disaster that is Microsoft is also a good example for a market failure. At fault is the US that never managed to do any meaningful anti-trust action against MS when it would still have accomplished something.

How repulsive.

"No backup" is amateur-level. Also that they did not use n-out-of-k with n k is a pretty basic mistake.

Quite true. Unfortunately, MS crap is also a really good example for a market failure.

Indeed. Windows and MS Office are a disgrace to the whole human race. No product on that level should ever have long-term economic success.
