Conflicting questions

Hello there

So today I found two seperate questions in the kaplan book and it seems to be conflicting with each other

Question no 135 asked whether the following statement is true or false

“When an item of property,plant and equipment is revalued there is no requirement that the entire class of assets to which the item belongs must be revalued”

This statement is apparently false
I don’t understand why because in your lecture notes it says
“If one asset in a class is revalued, then all assets in that class should be revalued.”

Also immediately after there is another question that was exactly like this asking
“If the revaluation model is used for property, plant and equipment,all items of property plant and equipment must be subject to revaaluation”

For this the answer was obviusly true and the correct answer also said that it is true

But doubt is why are both of these statements that look exactly the same showing two different answers???
