Ouch! That's harsh.
We had a question like that last year - where we were asked to name the molecule that transported energy - or something like that.
Everyone said "ATP" - but only those who said "Adenosine Tri Phosphate" got the mark.
In terms of your examples - saying "ambient air" is a bit mean. I do agree that you should be more specific - saying the "temperature/ph of the container/air/solution" - or something like that. I'd say you should expect similar marking on the exam. They don't care if you've understood the question - just that u've met their rubric.
So I guess you've got to be a specific as possible. If you have the edrolo textbook - they should provide a marking rubric for each question. As painful and inconsistent as it can be, it is worth looking at it and trying to tick each box.
For the exam - there were similar type questions year to year - and by looking at the exam reports you could develop template response to them. (I attached a PDF of a doc I made last year which may help)
Anyway, hope this helps and good-luck with the year!
