Quiz

Hello:
I tried to set up a quiz with structured questions (The questions are similar to the following sample) but got stuck half way.  Could you please help and advice if such question design is feasible in Moodle using its Quiz module?  Many thanks.

Sample Structured Question:

      Answer:  (2 marks for each correct answer, max 2 answers, total: 4marks)
                    Sampling rate (2marks)  / Sample size (2marks) / Channels (2marks)
1.3 Name 2 common audio file formats which have been covered in class (4 marks)

I have successfully created this sample question on Moodle using question type "Embedded Answers (Cloze)" as follows:

---

1. Figure 1 shows a device which can be use to capture sound.

1.1 Name the device (2 marks)
Answer: {2:SHORTANSWER:=Microphone~%50%Mic}

1.2 Name 2 audio attributes of uncompressed audio files. (4marks)
Answer: {2:SHORTANSWER:=Sampling rate~=Sample size~=Channels} {2:SHORTANSWER:=Sampling rate~=Sample size~=Channels}

1.3 Name 2 common audio file formats which have been covered in class (4marks)
Answer: {2:SHORTANSWER:=Wave~=MIDI~=MP3~=Real Audio} {2:SHORTANSWER:=Wave~=MIDI~=MP3~=Real Audio}

---

However, the above would not check for duplicated answers. i.e. if I enter "Sampling rate" "Sampling rate" as answers to Q1.2.  I will still be granted full marks.

Do you have any suggestions?  Many thanks.
