What is the correct answer to this question?

How would you use querySelectorAll to obtain a reference to all elements in a document with the class student-info and assign it to the constant studentInfo?

const studentInfo = document.querySelectorAll ^^ because it is saying this is wrong.

You need to pass in a CSS-style selector to querySelectorAll which is .student-info that has a period in front of the class name.

      const studentInfo = document.querySelectorAll('.student-info');

What Mei Lee said is what you need to do. If doing querySelectorAll(), you need put the . for class or # for ID inside quote marks inside the brackets.

You can read more about it in the developer documentation:
