First of all, congratulations on being invited by OC&C!
This is indeed an interesting question which is probably relevant for quite a lot of users, so I am happy to provide my perspective on it:
- Generally speaking, this type of question is called verbal reasoning, i.e. here you need to assess what statements are right based on the information provided.
- To practice this type of questions, I would advise you to have a look at the Verbal Reasoning section of GMAT prepareation material or other tests. Also, I am sure there are a lot of threads on PrepLounge on this matter.
In case you want a more detailed discussion on how to best prepare consulting online tests, please feel free to contact me directly.
I hope this helps,
