<?php
foreach ($_POST['questions'] as $q) {
        if (trim($q) != '') {
            $qtitles[] = $q;
        }
    }
	
foreach ($qtitles as $qtitle) {
        $query = "INSERT INTO questions (qtitle) VALUES ('$qtitle')";
        $result = mysql_query($query) or die("ERROR: $query. ".mysql_error());
    }
	
    $qid = mysql_insert_id();

    unset($query);
    unset ($result);


foreach ($_POST['options'] as $o) {
        if (trim($o) != '') {
            $atitles[] = $o;
        }
    }

    foreach ($atitles as $atitle) {
        $query = "INSERT INTO answers (qid, atitle, acount) VALUES ('$qid', '$atitle', '0')";
        $result = mysql_query($query) or die("ERROR: $query. ".mysql_error());
    }
?>

mysql_insert_id() gives you the ID of the most recent INSERT command you run.
In your code, you get the qid only once after you finish inserting all the qtitles, this is why you only get the qid of the last qtitle.

You should do the mysql_insert_id() after each INSERT, within the qtitle foreach, and nest the atitle foreach in the qtitle for each (after the mysql_insert_id)

The code should be something like this.
with an exception - the following code will insert all 6 answers for both questions. It's up to you to decide which answer should go with which question and handle this within the answers foreach.

<?php
 foreach ($_POST['questions'] as $q) 
 {
	if (trim($q) != '') 
	{
		$qtitles[] = $q;
	}
 }
 
 foreach ($_POST['options'] as $o) 
 {
	if (trim($o) != '') 
	{
		$atitles[] = $o;
	}
 }
  
 foreach ($qtitles as $qtitle) 
 {
	$query = "INSERT INTO questions (qtitle) VALUES ('$qtitle')";
	$result = mysql_query($query) or die("ERROR: $query. ".mysql_error());
	$qid = mysql_insert_id();
	
	foreach ($atitles as $atitle) 
	{
		$a_query = "INSERT INTO answers (qid, atitle, acount) VALUES ('$qid', '$atitle', '0')";
		$a_result = mysql_query($a_query) or die("ERROR: $a_query. ".mysql_error());
	}
 }
  
 unset($query);
 unset ($result);
 unset($a_query);
 unset ($a_result);
 
 ?>
