if there is possibility of multiple answers please mention it, i tried to go for a best possible among and 1 and 3 …, marking individually 1st and 3rd option was incorrect…, its not acceptable…
May be the question changed since I took the course but the question was “Which of the following are recommended ways …”. The plural seems to indicate that more than one way is recommended. May be it is a language thing, but I am not native English myself. Also in my exam it also says “Check all the answers that apply.”
But since I took the course in August may be the wording has been modified.
There is a mention in bold saying: Check all answers that apply
Let us know if we can improve on this.
