Answer:
In the given sentence the quotation marks should be added:
before the first ellipsis and after the period
The punctuated sentence would be:
Felicia wrote, ". . . I’ve dreamed since childhood of working on a ranch . . . where thoroughbreds were raised."
Step-by-step explanation:
The quotation marks are the punctuation which is used to denote the exact words spoken by the speaker. In the case of ellipsis in a sentence, the quotation marks are used before the ellipsis. In case the ellipsis is at the end of the sentence, the quotation is put at the end of the ellipsis, enclosing them.
