PAt question TFE

This is from achiever..

How would you know that the line represented on the "top" section is curved and not straight?

Man this is messed up...apart from the "top" section..how does the lower left section correspond to the correct answer...what happened to the smaller circle..

did i am on the same boat. i have NO clue how one would differentiate in such little time given on the PAT. Rediculous.
 
sometimes you can't.

but for this question.

The key here was to look at the the lower left hand corner with the hidden lines that represent that little circle and the bigger circle behind it.

you should have seen 4 hidden lines for the front view. that alone eliminates b and D leaving you with just with A and C. Even C is a bit spotty on having all 4 but its a screenshot so its hard to tell for sure if it has 3 or 4.

from there are several areas you can use to say that C is incorrect. the easiest area is that upper right. Its suppose to be hidden lines rather than a solid line.

How did you approach this question to come to choice B?

i guessed. I still dont understand how a person can differentiate whether there is a curved or solid line that defines the figure.

don't stress over it. as I said sometimes there is no way. you have to base that its is curved or straight on other views provided.

In this example it easily could have been both. There is nothing provided that could be used to say it it is one over the other.

it is highly unlikely that between two choices every little thing is identical with the expectation of it being a curved or solid line.

now that you mentioned it i actually see what you meant by narrowing down the choices between the 2 of the other ones. But my question would be now that how do you know those circles would be " hidden" lines when viewing it from the front?

for sure B isnt the answer. bc if you look at the end view you need to have a dashed line not sold line. and also, B doesnt should the two cirlces, so B is out. D is out bc it has the slanted angle on the top. so you need to choose between A or C. so based on look of C at the bottome part you can elminate the C. and the answe is A.

+1...

Man, my initial respond I thought the correct answer was B...HAHA....and hence was confused as to how the bottom left corresponded...my bad...

Just based on that you can figure out the final answer..

As Herkulease said, its not necessary to figure out the entire figure...details like this will get you the right answer..

In step 1 of the picture you can see the circles kind of are a give away in that you are choices are down to A and C. The outer circle has its own edges as well as the inner circle which would have its own edges as well. Since there are 4 possible edges that could be seen thats what you look for in the answer choices.

In step 2 of the picture you can see the main difference is the huge chunk of the block, is it protruding out or is it going in. If it were protruding out, the top end would have reflected that in that it would have had a protruding portion of that as well as seen in the modified top view. We can deduce down the answer choices to A and thats what we get.

Hopefully this helps.

My bad for misspelling "protruding"
