Final answer:
Giles Corey dies by 'pressing' in Act 4 of 'The Crucible' when heavy stones are placed on his chest, and he bravely refuses to plead, only asking for 'more weight'.
Step-by-step explanation:
Giles Corey, a character from Arthur Miller's play The Crucible, meets a tragic end in Act 4. Giles dies by a method known as pressing, where heavy stones are gradually placed upon his chest in an attempt to force him to plead to the charge of witchcraft. However, instead of giving in to the court's demands, Giles' only response is to bravely demand "more weight," effectively ending his own life without surrendering his integrity or implicating any others in the witch trials of Salem. This act of defiance both highlights Giles' character as one of principle and also stands as a criticism of the injustice and moral hysteria present within the trials.
