@T97,Great question. "Bring about" and "necessary" can introduce necessary
conditions, but they don't always do. This is because there could be
other words before them that qualify what they're referring to.
Consider this sentence:
Clouds can sometimes bring about rain.
"Bring about" isn't introducing a necessary condition here.
Here's another sentence:
For teachers, it is occasionally necessary for them to discipline
their students.
"Necessary" isn't introducing a necessary condition here.
Does this make sense? Let us know if you have any other questions!
