Answer:
Insisted.
Step-by-step explanation:
"Said" is used to refer to the act of voicing out, speaking, or expressing something vocally. It is the participle form of the verb "say".
In the given context, "said" can be replaced by the word "insisted" in the last sentence. This keeps the meaning of the sentence while still relaying the intended message that Nelson wanted them to 'retry' experiencing the restaurant.
Thus, the correct answer is insisted.
