Some questions about the RAADS-R Autism test

When filling out the RAADS-R 

embrace-autism.com/.../

The response options are 

1. True now and when I was young
2.  True only now
3.  True only when I was younger than 16
4.  Never true

But I'm a bit unsure what I should put if something is sometimes true but sometimes isn't. Should I put option 1 because that is more accurate than option 4. But if it isn't true all the time then option 1 doesn't seem that accurate either.

I'm also confused what to put in response to questions like 

"I have a hard time figuring out what some phrases mean, like 'you are the apple of my eye.'"

because I do know what it means because I've learnt what it means, but I can't work out why it means that. So how should I answer?

"I am considered a compassionate type of person" - this one, I think other people would consider me a compassionate person, but I thinks that's probably because of masking or something, so not sure what I should answer this one.

I think I am probably over thinking all this, but it's important I get this right, especially as I want to show my results to my GP if I ask about getting a disgnosis.
