The correct answer is B. Can someone explain to me why B is the correct answer? Thanks.
 
not really sure how to upload a pic, but it seems to work if you right click the small blue square with a question mark (in the second post of this thread)
 
If you do Kaplan's "event" counting, B and D are the only two that fit the criteria of matching up number of events from the top view and front view (The 4 horizontal events in top view = 4 vertical events in end view and 4 horizontal events in front view = 4 horizontal events in end view)

No, between B and D, the main difference is from the end view, either you can see the hole going through the center or you cant. If D were true, then the hole (the two dotted lines in the top view) would have to be on the edge so that you would be able to see it from the right. But from the top view you can tell that the hole is in the middle, and from the front view, that on either side, there is a wall around the center hole. So, from the end view, you will not be able to see the hole, so it needs to be a dotted line, so B is your answer, not D.

If that doesn't make sense ( and it probably wont b/c it was a terrible explanation so I'm sorry) then ask the "wicked sick PAT tutorial" guy...he'll do a color-coded version that will be much better than what I just said.

I think I figured out how to post a pic. Sorry for the previous misfires. Here is the pic:

Well if you look at the front view, you see two solid lines (horizontally) which tells you there are 2 changes in height...then, the shorter solid line tells you that you can't see it from the end view, therefore you would see a dotted line! So you can eliminate choices C, and D, because they aren't even close to be the right answer. Choice C because of the solid vertical line and choice D because of the solid horizontal lines. This leaves you with choices A and B...As we had predicted both choices A and B show 2 dotted lines which show the height changes, what makes choice be the correct answer is that short vertical dotted line that could be predicted by looking at the top view!
I really suck at explaining things, for these type of problems, you need to get a hold of Sama! lol He does it perfect!!! But hope it helps a bit though!

Count the lines...

The front view has 4 horizontal lines, so the end view should have 4 horizontal lines; this doesn't eliminate any answer choices (they all have 4 horizontal lines.

The top view has 4 horizontal lines, so the end view should have 4 vertical lines: eliminate choices A and D (only have 3 vertical lines).

Now you have choices B and C. For C to be true there would have to be dotted lines on the front view, but there are not: eliminate C.

The answer should be B.
 
Thanks to those who replied. I have a follow-up question: If B is the answer, how can we see a notch from the top view? According to the end view of B, the top box that goes all the way through would cover the view of the notch created from the second box.

According to the dotted lines in the top view, there must be a height change that we can't see from the top view, which goes through all the way!
 
OK B is the answer. Here is why. First you know that there will be a hole going through that you can not see from the end. That accounts for the hole in the middle of the object in all 4 views. However there is also a solid bar on the bottom which can be seen from the front. Therefore thee has to be a piece sticking out on the bottom left side of the end view whick leaves only A and B. Now to eliminate A there is a piece on the top view that incrops up towards the middle of the image. That little piece can not be seen from the end and therefore is represented by the second vertical dashed lines going through the hole in the end view. Any questions feel free to ask.
 
There has to be a mistake for his problem. The top view and front view clearly show a bend in the block on the "top layer" of this three layer structure. Yet, there is no dashed line on the "top layer" of this three layer structure in the end view for answer B.

Answer B is still the best choice, but not fully correct I believe.
