中等MATH-EXAM-008
A long question has parts (a), (b) and (c), and (b) says 'hence'. You should
A. ignore (a) and start a new method
B. use the result of (a); if (a) is unfinished you can still apply a stated result and continue✓ 答案
C. skip all later parts, because 'hence' questions have no method marks
D. copy the question into the answer space
解說
'Hence' points you at the previous result. Later parts are often marked follow-through, so stopping because (a) was incomplete gives away marks you could still earn.
