Randomizes the list of foils. |
|
Respects |
|
- each foils desire to be randomized |
|
- the existance of Concept groups of foils (select 1 foil from each) |
|
- and selects a single correct statement from all possilble true statments |
|
- and limits it to a toal of $max foils |
|
|
|
WARNING: this routine uses the random number generator, it should only |
|
be called once per target, otherwise it can cause randomness changes in |
|
homework problems. |
|
|
|
Arguments |
|
$max - maximum number of foils to select (including the true one) |
|
(so a max of 5 is: 1 true, 4 false) |
|
|
|
$randomize - whether to randomize the listing of foils, by default |
|
will randomize, only if randomize is 'no' will it not |
|
|
|
Returns |
|
$answer - location in the array of the correct answer |
|
@foils - array of foil names in to display order |
|
