Answer: As I walked down the hallway, all the lockers were open.
Explanation:
This sentence incorrectly suggests that the locker were walking down the halllway. To modify this, we need to add a subject.
Answer:
Hi! The word "another" here is an addition word and it represents that both of the sentences go together and support the same view.
Addition words tell you that the writer’s thought is going to continue in the same direction. This means that the writer is either going to add more points, details or ideas of the same kind.
Hope this Helps!
