You throw a dart at a dart board, it veers to the right EVERY time you throw it. Whether you throw it once or multiple times.
Is this an example of:

Poor Validity
Good Validity
Poor Reliability
Good Reliability

My 3rd year Psychometrics prof said this question is so hard to get right in the previous years he gave it to us in advance to see if this years class gets a better average grade on this question.
Its a multiple choice question on my upcoming exam, but if you know the answer please explain it so I too can understand it.

Poor validity and good reliability.

Or good reliability if you can only choose one.

That's the obvious correct one to me too.. But I feel like for a 3rd year class, the question wouldn't be so simple.
It's why I think it might be something else.

this^^... except "veers to the right" each time does not necessarily mean it veers the same amount... So if we need to choose one, I'm going to go with poor validity.
