As to your question about magnitudes, I don't know what you mean.
I'll try to explain my question...
In your first post you said:
I have done the first magnitude on them. This week I am writing in the 2nd magnitude.
And in the second, you said:
When we need to do the next magnitude, I just need to change the sentences.
I'm not sure what you mean by magnitude.
Is one sentence about each illustration "a magnitude"?
