The two rhetorical techniques demonstrated in the passage are:
- hyperbole - The phrase "abandoned to a 20th-century paper shredder" exaggerates the consequences of not using the impeachment provision, emphasizing the gravity of the situation.
- rhetorical conditional - The structure of "If the impeachment provision... then perhaps that 18th-century Constitution should be abandoned" sets up a conditional statement that underscores the importance of the impeachment provision.
Therefore, the correct answers are hyperbole and rhetorical conditional.
