How can i combine sequential with random questions

From the above image i have two types of questions 1.Passage Based(type_id=1) and another Normal Questions(type_id=0) 2.Normal questions can can come from rand() but where one passage question came all the passage questions has to come one after one.

i want to call the questions randomly but when one passage question come in that the question should come in sequence related to that passage how can i do that

This my query of calling questions.:

$select=$conn->query("select * from tbl_testquestion where cat_id='".$cat."' and subcat_id='".$sub_cat."' and qu_status='1' ORDER BY  RAND() LIMIT $q_limit ");

The view part questions is like this in the below image passage question appeared in the Rand() So in the next question same passage related question has to appear
