how can you tell if the structure on the left side of the figure (behind the biggest right triangle) is touching the ground or not?

 

[futuredent22]

I think its safe to assume that it is

 

[tRNA]

yes, but how can you tell? I couldn't tell and I chose the answer showing that its NOT touching the ground, which was the wrong answer

this is a 2nd one i got stuck on

Isn't it B?

 

[dentalknight]

i think these figures always touch the ground. and for the second one question you put up, is the answer A?

 

[HowAboutDAT]

Although I'm not 100% sure, I'd have to say...B?

 

[PooyaH]

I'm pretty sure it's B, the key to this one is the small squares on the top...For B all the squares are the same size which matches the original unfolded image...For the squares are not the same size if you look at it carefully!!!

 

[HowAboutDAT]

As for an explanation for the first question, if you extend a line from bottom of the figure in question (the bottom of the face that looks like an L) it will be perpendicular to the base of the right triangle. If it wasn't on the ground I don't think this would be the case. Again, not 100% sure, just a theory.

jeez its so much easier to explain these things in person rather than on the computer!

I think it's B too, but the correct answer is A !!!
Have no idea how A could be the answer, in addition to the square stuff, the triangle in A is too pointy so A basically violates the actual figure in every way

There must be something wrong with the question 😀
Dude, it's obvious that the squares aren't the same size in A!

i think it's A. but this sort of question is lame..B could be an answer also.. but if you look at the trapezium closely( where the cube attaches, you will see small difference. On choice B, it's a bit longer..I think so.

 

[WhyMD]

It looks like a bad question.
A is wrong due to top box not having equal-faces (although this can be argued it's due to perspective.)
B is wrong due to the top of the trapezium not being slanted.

 

[futuredent22]

I see how it is A. Choice B is saying that the line of the bottom of the figure is parallel with the line representing the bottom of the cube resting on top if it. But when you look at the figure, it is obvious that those two lines are not parallel, making it choice A.

i agree, but the square size violation in A is just as bad as the line violation in B, so in the end both may be wrong, it really worries me that this bad question is coming from ADA's test online...even the real dat contains errors (sigh)
