Either d or c not very sure but should be one of them
1. Your backyard is a Garden of Eden. (Biblical allusion)
2. I guess I should see this message about a new job as my burning bush. (Biblical Allusion)
3. When you feel betrayed by a friend, you can say, "You too, Brutus?" (allusion to Julius Caesar-Brutus betrayed Caesar)
4. You're a regular Einstein. (allusion to a historical figure)
5. When your parents learn about your new plan to raise money, it's going to sink like the Titanic. (allusion to a historical event)
cause-and-effect reasoning is mostly persuasive as it helps answer the question on <em>'how' </em> <em>one person, thing, or event causing another thing or event to occur </em> or <em>'why' something happens </em>making a statement objective and rational rather than a blind assertion/affirmation.
Hope this answer helps you, have a great day!
