If by pre-thinking you mean assessing what the answer should be before you look at the answers to the question then I would say most questions in verbal benefit from pre-thinking. There are some questions that will not fit the format, such as Except questions and some general inference questions on the Reading comprehension. It is very important to know what you are looking for in an answer so that you can more easily evaluate the part of an answer choice which makes it incorrect. Verbal is almost as logical as math and deserves to be looked at in the same way. The disadvantage of this approach comes when a test taker looks to create too specific an answer before going to the answer choices - you are only looking to get a general idea of what you want the answer to be, not to actually craft the answer. You must also remember to stay flexible when reading answers and not to be too fast to eliminate something that is in the ballpark of your idea.
Another advantage to this technique is that when you are reviewing questions you can determine whether you had the correct thinking but picked a wrong answer or if you had incorrect thinking for the answer. this type of review is invaluable in helping you to craft your approach to questions
