Answer:
The excerpts which show that Queen Elizabeth's response to the Parliament's request was rhetoric are:
1. The realm shall not remain destitute of any heir that may be a fit governor, and peradventure more beneficial to the realm.
2. For though I be never so careful of your well-doing, and mind ever so to be, yet may my issue grow out of kind, and become perhaps ungracious.
Step-by-step explanation:
Queen Elizabeth responded to the parliament quite persuasively. She appeals using logos to persuade the audience and make her point clear to them. She convinces them that she is capable enough to rule alone. She appeals them to give her strength.
She said that Parliament should not worry that she is not married or doesn't have any child. Having one doesn't guarantee that the heir would be competent enough to rule. She is herself quite capable to rule effectively and is a capable leader.
