Question

which transition word or phrase would best connect the two sentences? while some argue that social media can be detrimental to mental health, it also serves as a valuable tool for staying connected with loved ones. _______, it allows us to share lifes moments, even from afar. nonetheless in contrast additionally alternatively

Explanation:

"Additionally" is used to add more information. The first sentence mentions social media as a valuable tool for staying connected. The second sentence adds another benefit (sharing life's moments). "Nonetheless" shows contrast despite something (not the case here). "In contrast" shows a direct opposite (not fitting). "Alternatively" presents an option (not relevant).

Answer:

Additionally
