I thought all three could be used for benchmarking, but now I'm second-guessing myself after reviewing the material.

I have a vague memory that SUS is widely accepted, but I can't recall if the others are as well.

I think SUS is definitely one of the standardized questionnaires we studied, but I'm not sure about SUMI and WAMMI.

I think the key here is identifying which of these standardized questionnaires are commonly used for benchmarking usability. SUS seems like the obvious choice, but I'll need to double-check the other two options to be sure.

Okay, I remember learning about SUS and SUMI in my usability class. I'm fairly confident those two allow benchmarking, but I'm not sure about WAMMI. I'll make my best guess on this one.

Hmm, this is a tricky one. I know SUS is a common usability questionnaire, but I'm not familiar with SUMI or WAMMI. I'll have to think this through carefully.

I'm pretty sure SUS is a standardized questionnaire that allows benchmarking, but I'm not sure about the other two. I'll need to review the details on those.
