Yeah, it just adds noise without improving the model.

I thought adding variables always increased complexity, not stability.

Wait, are you sure? I thought it could mess things up.

Adding a non-contributing variable won't change R-Square.

I thought that R-Square could only increase or stay the same, so I’m leaning towards no change in R-Square.

I feel like adding a variable that doesn't contribute could actually decrease the model's efficiency, but I can't recall if that affects R-Square directly.

I remember that adding a non-contributing variable shouldn't really affect the R-Square, but I'm not entirely sure.

I think I practiced a question like this, and it mentioned that R-Square always increases or stays the same, so maybe it won't change?

This one seems straightforward to me. The script is not running, so I need to look at the options and see which ones address that issue directly. I'll go with A and B, as they seem the most relevant.

Hmm, I'm a bit unsure about this one. The TOGAF template has a lot of different sections, and I'm not entirely familiar with the specifics of each one. I'll have to think this through carefully.

I remember something about log files being in flash memory, like in a practice question we did. Was it flash:/ ?
