AWS Cloud Practitioner - six advantages

Hello, there is an issue with the rendering of the exercise in topic (visible also in the image below).

I click on the lens with - but still cannot see the chart, it disappeared all of a sudden while I was moving the blocks.

In addition, I have to maximize the browser window, otherwise I cannot see what is there. It is not possible to reduce the 2 left columns.

Thanks.

Then which is the correct combination?
I find that 2 options (“Trade fix expenses for variable ones” and “Benefit from massive economy at scale”) are both for the second block. Those are the answers that I found in all the mock tests (also on AWS skill builder) that talk about cloud providers offering of aggregate usage and pay-as-you-go.

Thanks
