Try this way 

for (var i in variable) {
    var k = variable[i].Education;
    console.log(Object.keys(variable[i])) // displays all keys
    for (var j in k)
    console.log(Object.keys(k[j])) // displays Education keys
}

your "variable" is an array so yon can't show a proprety of an element until define correctly where is the proprety.

as : 

console.log(variable[0].Education)

or doing a loop :

for (var i = 0; i <variable.length; i++){
   console.log(variable[i].Education);
}
