No way, I thought just setting it would be enough.

Definitely export MYVAR=value for it to work!

Wait, why is it empty? That seems weird.

I think it needs to be exported, right?

Just set MYVAR before running the script.

I thought you just needed to set the variable normally, like in option C, but now I'm second-guessing myself.

I feel like I saw something about using `env` in a practice question, so option B could be the right choice.

I'm not entirely sure, but I think setting MYVAR directly before running the script might not work as expected. Wasn't there a similar question about variable scope?

I remember that environment variables need to be exported for child processes to access them, so maybe it's option E?

Hmm, I'm a bit unsure about this one. The options seem pretty technical, and I'm not super familiar with the details of this imaging system. I'll have to think it through carefully.

This one seems straightforward - the Product Owner is trying to understand the context and stakeholders, which aligns with the "See the Whole" principle of agile business analysis.

I've got a good feeling about this one. The options seem to cover some common drivers of service satisfaction, so I'll review them carefully and select the most relevant one.

I've seen this type of issue before. The key might be in the `startTest()` and `stopTest()` methods. If the `executeBatch()` call is not properly wrapped, it could be causing the coverage problem.
