Could someone please take a look at my code? It's a simple quiz with one multiple choice question and one fill in the blank.

When the user clicks on 'submit' I tried to show some kind of response with correct/incorrect images next to the question. It works with the multiple choice question, but not with the fill in the blank. How can I get the fill in the blank question to work. It always shows the answer as being wrong. Thank you.

Code:
answer_list = [
['False'],
['body','hips','knees']

// Note: No comma after final entry
];

response = [];

function setAnswer(question, answer) { 
response[question] = answer; 
}

function CheckAnswers() {
var correct = 0;

var flag, resp, answ;

for (var i = 0; i < answer_list.length; i++) {
flag = false;
for(var j=0; j<answer_list[i].length; j++){
resp = response[i].toLowerCase();
answ = answer_list[i][j].toLowerCase();

if (response[0] == answer_list[0]) { 

flag = true; 
document.myquiz.a1c.style.backgroundImage="url('correct.gif')";	
}
else{	
document.myquiz.a1c.style.backgroundImage = "url('incorrect.gif')";
document.myquiz.a1c.value = " ANS: False. Position the head snugly against the top bar of the frame and then bring the foot board to the infant's feet.";
}


if (response[1] == answer_list[1]) { 

flag = true; 
document.myquiz.a1d.style.backgroundImage="url('correct.gif')";	
}
else{
document.myquiz.a1d.style.backgroundImage = "url('incorrect.gif')";

}

}

if (flag) { correct++; }
}
document.writeln("You got " + correct + " of " + answer_list.length + " questions correct!");
}
