Hi,
There are MCQs which are hard to make a choice.
E.g. Consider the four statements I, II, III, IV.
Choose the correct option:
A. All statements are true.
B. All statements are false.
C. Only I and II are true.
D. Only III and IV are true.
E. Only II and III are false.
For open-ended questions, there is usually a marking
criterion, so there is still a boundary for responses that are
reasonably-acceptable by convention. Take project work for
instance.
Thanks!
Cheers,
Wen Shih
