I just attempted the listening section of 2004 4級。
I thought the instructions for part two, as per the example were to select some of the given answers 1-2-3-4 as ただしい and the incorrect scenarios as ただしくない。 It even reminded me not to forget to fill in both parts. To me this suggested that in some scenarios, more than one of the given answers would be true. So you could end up with two shaded in ただしい and two shaded in ただしくない If there was always only one correct, why have this option to tick right and wrong?
With this in mind I did the test, and indeed came across some that seemed to have more than one correct answer.
For e.g (this is from memory so maybe a little out) when talking about a song a boy said he really liked the song, a girl said she liked a little but it was loud.
The answer options were
the boy likes it - ただしい the girl likes it - ただしい they both like it - ただしい the boy hates it - ただしくない
However in the answer sheet there is no mention of this strange multiple way of answering each question and it just lists one correct answer per question. I am confused now how to mark my attempt! In those with only one correct I seem to have got it right, but as with the e.g above I would have marked more than one as correct, would this then just be marked as 0 then? I would have put it down as just the boy likes it if I had thought I was only meant to give one answer.
