 of Multiple choice to find <i>bias </i>of facets (examinees, text type/genre, number of items, field of study, age, length of the passage) through MFRM knowing that the raters do not have a say in MC type in the assessment procedure due to the objectivity
 of scoring, hence I am wondering another measurement technique should be taken to find it?  </span></p>
