Okay, let me think this through. "docker attach" is for attaching to a running container, "docker commit" is for creating a new image from a container, and "docker import" is for importing a tarball to create a new image. So I'm pretty confident the answer is A - "docker pull nginx".

Okay, I've got this. The key is to understand the differences between the options. I think option B is the correct answer, but I'll double-check my understanding just to be sure.

Okay, I've got an idea. Developing performance appraisals for all auditors could help ensure they're all being evaluated on the same criteria, which could promote consistency. But I'm not 100% sure if that's the most effective method.

Yes, I think the prohibition for shell banks is crucial, but I have a nagging thought about private banking accounts too. That might be relevant somehow.
