Question

equal and opposite motion
not change, because equilibrium means equal
will adjust to amplify the changed conditions
will shift appropriately to counteract the change.

Answer 1

Le Chatelier's principle predicts that if a chemical reaction at equilibrium is disturbed, the reaction will shift in a way that counteracts the change. Therefore, the answer is: will shift appropriately to counteract the change.
