I don't quite understand why C isn't the right answer. The rectangular hole in B seems to be a little lower and smaller. C seems to be a better match. Why is C wrong????!!!!!

I think C is wrong because if you look from that angle, you should expect to see 6 solid lines (including the edges) in the base part. Also you should see a tiny notch in that opening as well. Try to view it from the bottom up and turn the object 180 degree. You'll see more clearly why B is the correct one.

There should not be a notch at the bottom. Try to view it from the bottom up and turn the object 180 degree. You'll see more clearly why B is the correct one.

ok, I got it. Thanks. That tiny thingy should be seen in that rectangular hole. Key hole seems to be my weakness. I got:
Key-holes: 12/15 😱 😱
Top-front: 14/15
Angles: 15/15
hole-punching: 15/15
cube-counting: 15/15
pattern-folding: 14/15

what do u mean by 6 solid lines??? did u mean by 4?
I also think C is the right answer. because B has really long top, and it shouldn't be that long.

You caught me editing! I replied before looking at the explanation. The tiny thing at the bottom is not shown in the drawing though. I'm sure you can bargain with Kaplan to get some credit. 🙂
You should try some different pattern-folding and angles. I saw some crazy ones on my test. Some of them I couldn't even tell what the object was.

You get two from the tiny bar too. In case you haven't noticed, the lengths from the object and those in the choices do not need to be the same. As long as the ratios are the same, it's OK.

I am doomed anyways. RC will kill all my chances. 😡

regarding credit: I have reported more than 20-30 mistakes to Kaplan although I know that they won't give me a penny. It takes them a couple of weeks to say their answer is wrong but they don't bother to change their wrong answers. At this point, I can't trust Kaplan's answers anymore. If Kaplan says my answer is not the right answer I have to double, triple check with everybody

I still think C is the correct answer. I see 4 bars toward top and 2 tiny edge at the base. there is nothing wrong with it. C is the answer.
B is also the answer.

Therefore, Both B and C are correct. Whoever made this problem made mistake by putting 2 correct answers.

Hi. do you have the Kaplan Second edition? If so, please list all the wrong questions. Thankyou..

so...is it true that this question has two answers?

 

[dat_student]

no it has only one correct answer. Sorry for the confusion. Kaplan's answer is the right answer.

You must be looking from the back of the object. If that's the case, the two vertical edges of the opening must extend all the way to the bottom. That's why C is incorrect.

I don't recall if the real PAT will be asking keyhole questions of this kind. Models having internal hole(s) throughout would more be suited for Top-Front-End Section, where hidden lines come in at certain view(s)..

Put it this way... would you all think that the tiny (shaded) reactangular plane in answer B or C is going to hang viably there without any support of any kind? It's just my opinion... 😀

oh~ when u said two vertical edges of the opening..u mean the rectangular hole in the middle?

Hi,
B is the correct answer.
In C, the tiny ("U" shaped) piece at the bottom is wrong...it should not be there because it is at the same plane as the bottom surface.

no, NOT at the same plane. it's wrong because the tiny U-shaped object also has an upward projection which C doesn't show.

 

[isd121]

oh! i missed that...you are right 🙂
so that tiny U-shaped object should be upwards instead of downwords

no, NOT at the same plane. it's wrong because the tiny U-shaped object also has an upward projection which C doesn't show.

 

[dat_student]

up and down, both. It projects in both directions

 

[joonkimdds]

up and down, both. It projects in both directions

what!!! u guys talking about that tiny tiny tiny tiny thing at the bottom that's like 0.001 milimeter on the picture?
Come on...get a life... -_-;

 

[luder98]

Sorry my reasoning was confusing. I used top/front/end views to explain an aperture passing question! I think I'm going crazy!

The reason C is incorrect is because the tiny bar will bump into the shaded rectangular object if you pass it through that direction.
