How many concepts/terms? How would you revive the question?6 7. Question wordingPOLS2110-T32. Simple language: Clear and understandable avoid slang, jargon, and technical terms Short items are best (so that they may be read,understood, and answered quickly) E.g.,Do you agree that the Legislative Councils splitvoting system should remain in passing a bill? (If you dont study HK politics), which term you find itdifficult to understand? How to change the question so as to make itunderstandable7 8. Question wordingPOLS2110-T33.
