These people are in a chemistry lab in a university.  The older looking lady in the background is the professor, and the younger girl in the picture is a student.  The student is taking some big test, where she has to perform an experiment in front of the professor to earn her degree.  She is carrying out the experiment and the professor is very impressed.  However, she is very jealous of the student's abilities.  She is afraid that this brilliant, young girl might jeopardize her job because she could take it.  She decides to make sure this does not happen by acting like the student is doing poorly and fails her on the test.  The student gives up on chemistry, thinking she actually failed, and moves to Pakistan.
