I want to define a simple True / False question, but...
Problem is that the 'as' option requires the correct answer be the *first* one listed.
The assumption must be that setting (randomOrder = true) will cause the correct answer to be shifted around for different test instances.
This makes sense for other question types, but not for T/F questions, where maintaining a fixed order is important.

So...
  How do I properly declare the 'as' options for a T/F question, needing to keep a fixed answer order while still allowing me to define the right answer?

Hi Mike,

You should be able to use the 'hasCorrect' option to do this. From the docs:

'hasCorrect': If false, indicates that none of the answers is
privileged as correct. Otherwise, is either true, indicating that the
first answer in the 'as' list is the correct one; an integer, giving
the index of the correct answer in the as list (starting from 0); or a
string, giving the correct answer.

I.e., you should be able to set 'hasCorrect' to "TRUE" or "FALSE" (or 0 or 1).

Wow!  Hi Alex... I really need to lay off the coffee!  I'm stunned how I missed that after perusing the docs I don't know how many times.  Anyway, thanks!!

Hello!
I found this forum but I don't know if it's still working. I have the same problem Mike D had and I can't work it out. I am using the question controller with 5 answers that must be fixed in order. One of the answers is correct. It would be great If someone can give me an example of how it works.

Dear Gonzalo,

If you specify your answers as "as: ['a','b','c','d','e'] ", then you can specify "hasCorrect=false" if no answer is correct, and "hasCorrect: 'b' " if 'b' is the correct answer. Note that you cannot specify multiple correct responses however.

Hope this helps,
Alexandre

You have an extra comma at the end of your "as" array which may cause problems. What didn't work exactly?

Dear Alexandre,

Would you please let me know where I should add the 'hasCorrect: 'b'' to? My codes did not work:


[["TEST-locallong.A.1", 11 ], "DashedSentence", {s: "I received a new book"},
"Question", {hasCorrect: "Incorrect", randomOrder: true,
 q: "The book is not new.", as: ["Correct", "Incorrect", "I don't know", ]}],


Many thanks,
Jeremy
