<p>For the writing section does it follow real facts or simply grammar rules. I had a question about something that happened after World War II and I said No error. However, the "will cause" was the right answer. Is it because CB assumes we know that WWII happened a while ago and cannot be used in future tense? </p>
<p>Also, errors can be chosen for wrong vocab usage right?</p>
<p>I don’t think questions can (or should) assume knowledge of historical content. Also I don’t think the writing section tests bad vocab usage (although it sometimes tests redundant phrases).</p>
<p>Technically, the vocabulary errors you are referring to would be considered diction errors.</p>
<p>Ex., imminent vs eminent, or repelled vs. propelled, principle vs. principal.</p>
<p>As for generally accepted facts, yes, there is a chance that they may ask you about a past event. Usually they should provide enough context through the words to indicate proper tense usage, but there is a chance that they might throw in a widely known event like WWII and assume knowledge only because it is universally included in curriculum.</p>
