Quiz#1Fix the Code

According to the Quiz PDF documentation, this is supposed
//to draw stacked rectangles, not ellipses.  I think I fixed as many
//syntactical errors as I could find, but I'm pretty sure I missed the logic
//error somewhere.  There is still an 'undefined' message when
//there is an attempt to run this code and I can't see it.
console.log();

//This program is broken and needs to be fixed.

var objects = []; //This is an empty array that contains 150 objects
var numberOfObjects = 150;

    //can't put a finger on it.  I think this is where the 'undefined'
    //message continues to plague me.
