Final answer:
Sentences with informal language and hyperbolic expressions, as well as those that express personal emotions, are inappropriate for a formal e-mail.
Step-by-step explanation:
The sentences that are inappropriate for an e-mail with a formal tone are:
- “You can’t believe how many people die in car wrecks every year because they can’t get away from their phones.”
- “Everyone knows it’s a human right to be able to do and say whatever you want whenever you want to say it.”
- “I’m sick and tired of irresponsible drivers in their gas-guzzling vehicles not caring about what’s important in life.”
These sentences contain informal language, hyperbolic expressions, and lack the professional detachment expected in a formal e-mail. In an official or formal context, particularly when addressing topics such as the First Amendment and freedom of speech, language should be measured, respectful, and free from personal emotions that could undermine the professional tone.
