Replicate the formatting of the two end options that the NPS question has on a multiple choice quest

Hi everybody.

I want to make a nice looking question on a horizontal 0-10-scale + a don't know category. At both ends of the scale I need to have some descriptive text. Unfortunately this doesn't look nice, because the text can't be spread out. Can anyone help me what to do?

Below my question is as a NPS-question (which looks nice, but does not include the 'don't know' category) and in the bottom picture a multiple choice question. The text is in danish, but the category to the far right in the multiple choice question is the "don't know" category.
