Final answer:
Parris fears the potential for violence and bloodshed due to the metal that collects a severe response from the people in Andover.
Step-by-step explanation:
The fear that Parris has about the metal that collects a severe response from the people in Andover is the potential for violence and bloodshed. In the given text, Parris expresses apprehension that the actions of certain individuals or the soldiers may lead to a tumult and bloodshed. This fear arises from a belief that once blood is drawn, the situation may spiral out of control and cause widespread harm and damage.
Severe responses in colonial times could include uprisings, rebellions, or other forms of public discontent, often provoked by acts of perceived injustice or oppression. The fear of 'blood being drawn' implies a concern about violence leading to widespread conflict, as history has shown that initial violent incidents can escalate into larger confrontations, with far-reaching consequences.
