Maybe we are just talking past each other here. Lets start over. I think that when people are asked a question about which you have no prior knowledge and you simply look up the answer, then yes, you have answered the question.
Now if you are hired to do a job, lets say something neutral here; Welding titanium, and you know, thanks to your lookup that it requires special care/inert environments to avoid crystallization during the welding process, but you don’t know WHY...then you really don’t know anything at all and are guaranteed to hose the part if you try welding it without a lot more actual knowledge.
Would you agree or disagree..
That is not what happens in any open book test I have ever taken. Ever. Nor do I know of any professor who writes tests like that. Not one. Open book tests are usually harder, because the book can't help you. I have had exam questions that literally required inventing a completely new product to solve the need posed by the question using the principles described in the book. It is as if one had learned about transistors and was asked to use them to design a radio to meet specifications. I actually had an exam question that expected the students to invent Dolby as a noise reduction technique, knowing what they did about mathematical transfer functions.
In other words, you are completely clueless about typical open-book examinations in technical college courses. Stick with reporting, but I suggest you start with facts.
