| CJHughes | Questions that are designed to steal points. Answer 'C' means that answer 'A' and 'B' are incorrect. However, extremely easy and in my opinion logical to conclude that answer 'C' suggests that neither i, ii, iii or iv are correct based on how answer 'C' is worded. One thing to have to commit and recall from memory, another to have to recognise deliberate (or maybe just poorly designed) attempts designed to confuse and frustrate you in the process. |
