Grammer Post Week 4

That vs. Which
When I saw this in a rule book I had to stop and think if I had previously realized that, or if I had been making the same mistake all my life.
That is used in a sentence when something specific or important is being described like: " I don't believe that money is the root of all evil."
Which is used when what is being described is not important to the sentence like: " I don't agree with the statement which some people say, money is the root of all evil."
That referred specifically to the subject of the sentence. Most important.
Which referred to a something people say, not the actual statement which is the subject.
