Courses Plus Student 3,463 PointsConfusing Question
Not sure what they are asking here. Push adds to the end, Pop removes an item from the end. Shift and Unshift do the same to the front. None do both. Am I reading the question incorrectly?
"Which array method returns the first item from an array and removes it from the array?"

By return, they mean that the method returns the value back to the code that called it. Not that any value is added to the array, and the answer to this question is shift. Both shift and pop return the value that they remove.
As an example take this code:
var scores = [ 76, 79, 85, 87, 89 , 90, 99];
var firstScore = scores.shift();
console.log(firstScore);
76 will be printed if you run that code. That comes from the fact that scores.shift() returns the value it removed from the array, which means that you can assign it to a variable as I have done above. If shift did not return what it removed then the above would not work.

28,558 PointsCan you specify what exact question confuses you? There are multiple in the Quiz and it's not entirely clear which you are referring to. It would help if you edited your post with the question.
