Question

Which of the following sentences has a
Nonessential clause?
A. The particular key to success that makes the biggest difference is
hard work.
B. All students, whether they are performing or not, should report to
the auditorium.
C. People who study the science of mind and behavior are called
psychologists.
D. The person who invented the mechanical television was John
Logie Baird.

Answer 1

Answer:

B

Explanation:

This is because there is no explicit description of the students, just a generalization on whether they perform or not. The other options have an essential or explicit description of a prominent word(for option A, it's the description of hard-work, for option C, it's the description of psychologists, and for option D, it's the description of John Logie Baird).
