[Grammar] Why have you used the symbols in red above?

[kadioguy]

Why have you used the symbols in red above? There should be nothing before "Which" and there should be a question mark at the end of each question.

I am wondering about the tense. Didn't this happen in the past (i.e. before emsr2d2's reply)? How about saying these?

What do you think?

 

[SoothingDave]

It still should be as she said.

Thank you, but I don't know why.:-?

 

[SoothingDave]

"Should have been" is a possible way to say it. But it is needlessly wordy. They should be.

 

[GoesStation]

The angle brackets and slashes were wrong. At the time of writing, in the present, and in the future, no punctuation before "Which" and a question mark at the end would be correct.

 

[kadioguy]

Thank you both.

And how about the "Why have you used the symbols in red above?" part?

Compare it to "Why did you use the symbols in red above?"

 

[SoothingDave]

They both have the same meaning.

As an American English-speaker, I'd be more likely to use the past simple. I think British English-speakers tend to favor the present perfect here but I'm not sure.
