It is repetitive
Step-by-step explanation:
It says, “Frank and Gina went to the store to buy Christmas gifts and food, but it sold out of food by the time Frank and Gina got there.” It lists the names twice. This is unnecessary information to include them when it’s already been stated earlier in the sentence.
It should read, “Frank and Gina went to the store to buy Christmas gifts and food, but it sold out of food by the time they got there.”
