The Principal hardly managed to give the papers a cursory glance.

superficial
through
thorough
curious

The correct answer is: A. superficial

A cursory glance is a quick and not very careful look at something. It is a superficial look, which means that it is not very detailed or thorough. The other options are not correct because they do not describe a quick and not very careful look.

  • A through look is a careful and complete look at something.
  • A thorough look is a very careful and complete look at something.
  • A curious look is a look that is filled with curiosity.

The Principal hardly managed to give the papers a cursory glance means that he did not have time to look at them carefully. He just glanced at them quickly.
