Final answer:
In 'An Inspector Calls', Eric acts nervously, drinks alcohol, and displays signs of impatience before the Inspector arrives.
Step-by-step explanation:
In the play 'An Inspector Calls', the character Eric acts in a certain way before the Inspector arrives. Eric is shown to be quite nervous and on edge. He frequently drinks alcohol to calm his nerves and is often impatient and easily agitated.
For example, just before the Inspector arrives, Eric is described as being 'in a state when a chap easily turns nasty'. This suggests that he is in a bad mood and potentially on the verge of becoming angry.
Evidence of Eric's nervousness can also be seen in his dialogue and actions. He constantly interrupts conversations, displays signs of guilt, and seems anxious about the Inspector's impending arrival.
