Ideally, you would step away from whatever you just drilled/tested and come back with a fresh mental state that isn't necessarily still in the same mode as when you took the test. Then you would go through the questions as if you had not answered them without the time constraint or any other factors that would exist when drilling/testing. There's a button at the top right when doing blind review that lets you hide your original answers. I'd recommend doing that so when you go to do the blind review, you are actually starting fresh. Then you can compare your current answer to the one you chose previously and whether they were the same, one was right over the other, etc.. and take notes and whatnot

I may be wrong but it almost feels like more of a claim than an argument. Now if it was a bit more fleshed out and lets say... it was "We spend a lot of time away from one another. When I have an extended period of time away from you, it makes me miss you. I tend to hug when I miss someone. Therefore, I hugged you because I miss you." would make it an argument.

If you read it like "Train service suffers when a railroad combines, therefore, if railroad is going to be a successful business, then it must concentrate exclusively on one of these two markets."

Then it comes across clearer that it is directly in support of the conclusion. The support comes in because it is providing context for why a railroad would not be successful if doing the stated action. Bad service = unsuccessful business
