Don't we know that D must be true though? The last sentence lays out that "every effective teacher is a good communicator," and if you replace effective teacher with good communicator in the first sentence, you get D. This doesn't fall into the same trap as B, since it already says lecturers, which is equally modifiable by both "good communicator" and "effective teacher."

LG is probably the easiest section to improve on. Every question can be tackled if you know how to approach it, so I suggest you watch some videos on how to set up sketches and then do some questions. You can even go back and redo some of the ones you've already done, because trust me, you won't remember the deductions you made a week ago.
