Can someone please explain why E and not D is the answer to this?
if you look at the back of the front side, the whole part is covered and will be E. I can see why you answer D because if you look at the top, it is similar. However, looking at the top, the hole in the middle will be more rectangular than square like D.
oh hahahah wow... so sorry to ask that. It's so obvious now! Thanks! 😀
Actually I'm having trouble with one other one---- Can someone explain why B can't work in this case? (the answer is E)
if the picture is showing the face of the object it needs the cutout part...also the piece going across is too thin and the distance of that piece from the top of the bigger piece is greater than it should be...answers like B are designed to trap you since it looks like the original object so dont forget to try and rotate it in your head to see where it fits. Make sure you look at thickness of different pieces on the original cuz that was a common trap on my DAT
So just to make sure I understand this... if the object has a hole, I should assume that the hole it goes through has to outline it? Is that always the case?
for the most part yes and as long as the thickness of the piece matches as well
Is the distance from the top really incorrect? When I compare the position, I use the back of the front object, and the front of the back object. This gives me a better idea of where the lines intersect. By doing that, it does seem correct.
It's close it probably is correct it just looked a tad off at first glance
The distance isn't the issue, it's that the aperture is the right shape, but there's going to be extra space around the object.
When I first started doing CDP problems I didn't realize that you can't just pick any aperture that the shape fits through, you have to pick the one it fits through PERFECTLY. That means you cannot pick an answer that will leave your shape with extra space around it (well you can, but I'm guessing you want a good score).
In B, the right side of the shape would have some space between it and the edges of the keyhole, so this isn't the right answer.
To weed out trap answers like this, it helps to really think about what aperture (the actual name of this keyhole section) means, i.e. a whole that light comes through. Just imagine that the keyhole is a hole in the wall in a dark room, but there is a really bright light on the other side of the wall. You want to find the whole where you can orient your shape to plug up the aperture such that it slides into the hole AND blocks all of the light.
