Not doing it isn't really the appropriate option.If you believe the teacher handed out the wrong worksheet, askthem. If you didn't look at the worksheet until you got home, readit and try to figure out how your reading assignments and classlectures apply to the worksheet question.If, for example, the question is from your chemistry teacher andis about titration, think about what the titration process isactually doing and what you are measuring. Although the wording inthe worksheet question might not precisely match problems you didin class - you may know more than you think. It is called "thinkingoutside the box" and gives you the opportunity to apply what youlearned.If your teachers never covered the subject of titration or nevergave a reading assignment for it, that could be an issue - althoughyou could do a bit of research on the subject and come up with adecent answer. The teacher could be checking on the class's generalknowledge and capabilities before starting a new unit.Put in an honest effort. Don't shrug the shoulders and give upso quickly.
