NOTHING again!

Consider the statements below:

the use of literature to justify the research problem.

the use of literature to support the need for research questions.

Which shows the difference between qualitative and quantitative research?

To me, every research NEED research questions. So the use of literature reflects the research problem , and hence support the need for research questions. Hence the second statement cant show the difference between the 2 forms of research.

The key difference apparently is in the research problem vs research questions. I should have focused on key terms "research questions" arising from literature for quantitative research, and not have tried so hard in understanding and analysing the sentence meaning. So the student that identify key words will get it correct. How ironic!

This kind of semantic twist to award a conscientious learner with zero when one got 4.5 correct out of 5 correct is HARD to swallow! Even given that I have been ignorant and grossly wrong, do i deserve zero for a half error?(for those who are curious, one of the questions require ticking 2 answers).

I half wonder, is it because the system cannot compute 5% out of the total score (due to????) or there is a lack of knowledge of assessment purpose. I can think of more acerbic words, but i guess it suffices to make my point.
