Actually I am coping and pasting the question as exactly as it looks from the gmat course provider.

Ok so this only goes to show that you need to mention your source in the questions you post if you select the tag "Source-others please specify" because some sources are notoriously average. GMAT language is very clear and only a handful of companies are good at producing good quality questions.

I have reverted back to the original language.

I think the purpose of them having such questions is to train students to sort out information and extract only the most important details, as business managers must do in the real world.

My idea is to share those so that I can stir discussion on quality, method of reasoning, solutions and skills applications

Ok. Good point. I have updated the question again to your original post.
