Final answer:
The word in bold type, "nous," should be replaced with the pronoun "vous."
Step-by-step explanation:
The word in bold type, "nous," should be replaced with the pronoun "vous."
The sentence translates to: The kind gentleman showed the way to Manon and me when we got lost.
Since "Manon and me" is the direct object of the verb "a montré," the pronoun used should be the direct object pronoun "vous."
