I feel like separating them might be better. D could work too!

Wait, can you really just merge date columns like that?

I vaguely recall something about imputation, but I don't think it applies to dates in this case. I lean towards option C for consistency.

I’m a bit confused about whether we should append or merge the columns. I feel like merging them could lead to issues if the formats are different.

I remember a practice question where we had to standardize date formats, so I feel like option C makes the most sense here.

I think we should unify the date formats before merging, but I'm not entirely sure if that's the best approach.

Hmm, I'm a bit confused by the wording of this question. I'm not sure if I fully understand the difference between the options. I'll need to re-read it carefully and think through the logic.

Okay, let me think this through. Remote site A uses G.711, so no transcoding is needed there. But remote site B uses G.729, so we'll need to handle that somehow. I'm leaning towards configuring the hardware transcoder on the site B router, but I want to double-check that.

Option C is the way to go - merge all date columns and unify the format. It's the date-iest solution, if you ask me.

Appending and parsing the date strings? That's like trying to read a calendar in a foreign language - it's going to take some serious linguistic skills.
