Dumb question

Ans 4:

Class : Class 6
The Toppest layer is the crust not the mantle. Y shows below Z ,and Zealand means mantlemail which is below the crust

I think this question is totally wrong- W is Inner core,X is outer core,Y is mantle and Z Crust so how can they(SOF) is saying that 'B' is the correct option

Ans 9:

Class : Class 5
Z is the crust. So answer should be C. Please update the solution as the solution also seems to be wrong. Diagram shows four layers and outer layer will be crust.

the solution of this question is wrong

Ans 20:

Class : Class 4
Z is crust not , Y is mantle

Ans 21:

Class : Class 5
guys, calm down. we do not stand on the crust, we stand on the earth. so z is the earth, y is the crust, x is the outer core and w is the inner core.If you go and see the information of the exam, the have not mentioned mantle, so what ever information is given, you have to follow it to get the answer. So the answer is B.

Ans 22:

Class : Class 5
The solution given is wrong. There is no explanation of why B is correct as Layer Y should actually be Mantle.

Ans 23:

Class : Class 6
Z is crust and Y is mantle

Ans 24:

Class : Class 5
What a silly answer! Are dogs, trees and pumpkins growing inside the layers of the earth that they have given such a silly solution? What cheek!

Ans 25:

Class : Class 5
the correct answer is bb b b b b b b b.

Ans 26:

Class : Class 4
I was trying to report error but it was not submitting....

Ans 27:

Class : Class 6
Z is the crust as it is at the first. The solution has been written wrong because it is from planets question.

Ans 28:

Class : Class 6
The answer is C and not B because they told to select the correct option. Y is mantle and the option B they told crust. As Z is crust and covers most of the earth surface, it should be C.

Ans 29:

Class : Class 4
Z IS THE CRUST AND Y IS THE MANTLE OS THE CORRECT ANSWER IS C AS CRUST TAKES MOST OF EARTHS SPACE

Ans 30:

Class : Class 7
Y is mandle

Ans 31:

Class : Class 5
The diagram is also not labelled correctly

Ans 32:

Class : Class 4
The solution is completely wrong!Does anyone know the email ID,mobile no. or address of anyone working with SOF? We could inform them and then if that person can do it well and good or that person could tell the correct person.We need the solution to be correct.

All of you're worrying. The answer is B as per the MTG olympiad book. there the options were:W and X are liquid layersLayer above Y is crustLayer Z makes most of the earth's volumeall of theseTHE OPTION B LAYER ABOVE Y IS CALLED CRUST is correct in the book.As that is the ground and above the ground is the sky and atmosphere which is called crust and here its written SURFACE ABOVE Y IS CRUST because Y is land and above land is crust. All of you were thinking they told Y as crust and that's wrong but they said Surface above Y which is Z . They're correct.
