What is the difference?

That day my sister ask me a question

Primary school's BC question.

造句：那场人为的战争造成了许多无辜的伤亡。（The man-made war cause a lot of innocent injures and deaths）

我告诉我妹，战争肯定是人为的，没有天然的战争，所以不用写人为。

I told my sister that war is always man-made, so the word "man-made" is not necessaries.

她告诉我是从书上抄来的。我叫他去问老师。

She told me that she copied from her book, I ask her to ask her teacher.

但她的老师却告诉她，那个“人为”是为了强调整个句子...

But her teacher told her that the word "man-made" is used to emphasize the sentence...

哇？如果是这样，那我在考试写这个句子：我的妈妈是女的。

So if the situation is like that, if I write this in my exam: My mother is a woman.

请告诉我，我的华文可以拿A吗？?

Please tell me, Can I get A in my BC paper??
