Question 2 
They were so innocent because they used to always go camping with each other and now they camping invasion happened so they have to be careful of everything they do 

Question 3
That they are going to do anything to wreak Australia and they are demonstrating not to mess with them or they will get invaded again without them knowing and they are willing to do anything in their power to destroy everything 

Question 4
They used the bike quietly with not making a sound and stuck to the dark shadow road where no one can see them.

Question 5
Her emotions show that she is scared and worried but she is also emotional because of her shivers  

Question 6 
She gets very angry because of her friend or family member because  Chris is meant to get cars with the soldiers and if Chris is not  looking out for the invaders then he won't know what is going to happen and it  will be easier for them to do what they want and it is also easier for them to take the teenagers.
