Frm the question, you're asked to 'hurai mengikut sektor
So, you'll need to go frm one sector to another.
And yea, you'll need to hurai the pola.
Each pola one paragraph.
Naik turn, terus meningkat, terus menurun, and tidak konsisten.
An examinar advised us to give an extra point, which is the minimum and maksimum kind of perbandingan.
Because the answer scheme may consider this as a point.
They may not.
So it's always better to play safe. (but I doubt candidates will have that much time to 'play safe' by writting an extra point for each essay)
As for the sebab, I think so it should come after the pola in each paragraph. Because the question asks for "Jelaskan sebab keadaan sedemikian
." So you'll need to explain why it keeps dropping, or keeps raising, or it's not consistent etc.
For the sebab kind of thing, it's hard to generalize like this.
You'll need to look at more examples, eventually you'll know which sorta question requires which sorta answers.
Again, we may be unlucky. The whole world may agree with this kind of answer, but if the answer scheme is of the other kind of answer, then we are considered wrong too
The answer prepared by MPM is unpredictable, as in, there may be some exceptional cases. So we'll need to depend on luck too.
