So I have uploaded a question from CDP on keyhole.
For the picture attached, the right answer is not shown, but I wanted to ask:
1) For choice A, there is a big hole. What happens if that grey hole was white? I could still slide it through, right?
2) Also for choices A and E, do those tiny holes have to be there or would I still be able to slide it through?
3)Lastly, how do I figure out when there should be holes, and when there should not be? For example look at choice D, they have no holes at all. Is D more correct than A and E in terms of the hole situation?
Thanks!
