P
Fall
Q
Still stand
.
Study the information given. And think why it happened. Why model Q still stand?
Think of the science concept you have learnt? eg: stability
Look for information given in the question:
Model Q still stand and model P fall. Why?Answer:
Q is more stable than P
C3: State one observation to support your reason (inference) in .Model
