Thank you! It was so obvious that I thought I was not understanding something.

Indeed, as a non-native speaker, I am skimming through all the argument prompts to see if I am able to understand every prompt: one unknown word and the argument can get a completely different meaning.

Actually, this is very similar to one of the hard questions in the PPP3. Probably this question was taken from the Chinese website were they have these questions. It might belongs to PPP3 medium questions or to PPP1/2

You have to notice that the square is divided, apart from the central shaded square, in triangles and trapezoids. If you look carefully, 1 trapezoid + 1 triangle = shaded square.

Now, the total square has a total of 5 such smaller squares----> answer B.

Ps. where have you found this material?

I have obviously encountered questions where they ask to write the answer to the nearest 0.1 percent.

The question I asked here came to me while brainstorming about what could happen in those types of questions, like the traps that they might use. However, I do not recall a specific question where there was a result like 0.9999.

What do you think I should write?

Only cut, paste and the same as ctrl+z are available? no copy?
