// This section is where you put the test.  You can choose either a true/false type or 4-item multiple choice.
// Since it makes sense logically, I've integrated what would normally be stand alone answer key and link reference
// with each questions. Make your changes only in those areas enclosed in single quotes. 

// General syntax rules: Do not use a 'single quote' mark in the variable text. Standard URL links (using standard
// format) are expected in the linkRef definitions. 

// Correct answers lead with: "If you 'guessed' at the answer... "
// Incorrect answers lead with: "To review the material... "
