Respuesta :
The correct answer is option D) Revise “finally” at the beginning of Sentence 5.
In this case, the author is writing about pets in the USA but it is not providing a chronological order for that. And the sentence connector "finally" is usually used when giving an order together with other connectors such as "first, second, finally".
Option A should not be revised as the sentence connector "for example" is providing evidence for the previous statement.
Option B is also correctly used in the sentence since the connector "however" is indicating a contradition between ownership of pets and how they are acquired.
Option C is also correctly placed in the sentence since the connector "specifically" is providing concrete examples of the previous sentence.
