Okay everyone, it seems to be that you guys really aren't paying any attention to the whole question.Dear friends, the question says that we have to decide the odd one out on the basis of composition(on what it is made of), not anything else.If you see it this way, Jupiter is the odd one out, not Earth,Venus or Mars, because it is the only planet made of gases, mostly hydrogen. All the other ones are rocky or terrestrial planets, made mostly of rocks and metals, molten or solid.

Actually, Jupiter is the right answer. They asked us to find the odd one out in terms of composition or what they are made up of. Since Jupiter is a gas giant with mostly hydrogen and Earth,Venus and mars are rocky planets with many valuable elements, the answer is D.

Ans 23:

Diya Jasmina from Samsidh MLZS, Bengaluru

ok, why is the answer to almost all questions in these chapters are wrong. They tried to copy the book but they (mistakenly) wrote the wrong answer. The correct answer should be E (made it myself cuz the answer is not there) Surface of Z is the crust. Man, these SOF people need to first read what they have written then upload it so we can study for our test. Even the Admin (Who has the master answer) has no words to say!!!!!!

Ans 20:

Shailaja Divakar from Chennai public school global school, London
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.

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.

The correct answer is C. I am disappointed with the SOF Olympiad. I recommend to not enroll the students for any of the Olympiad, as the material is not adequate and there are too many errors which will confuse children to make their concepts. We are pressurizing our children to take this exam and perform. But actually it will confuse our children instead of making their concept strong.
