Answer:
He invited Kevin for a walk.
Step-by-step explanation:
The reported speech occurs when the words spoken by a character, in a text, are not said by him, but by the narrator of the story. When this type of speech is presented in a text, the author must modify the verb tenses, so that the reader can identify who the character is speaking.
An example of a reported speech can be seen in the sentence above, where the narrator presents what the character is talking about through the sentence "He asked Kevim to take a walk."
