"We did not have a good system for a while."

Even being a very small town it has a good educational system.

"I quickly realized that this was not a very good system."

It's about time someone mentioned the good in the public school system.

That's almost never the case, even with a good system.

When have you ever seen me under a good system?

It was a good system of government, because most people want nothing to happen.

It is not a good system for the Minister to come and answer two questions after three months.

Without it, the sound was just fine, as one would expect from a good system.

It was a good system but one he didn't know.
