Test 3 (Subject-Verb Agreement) - Requires Respondus LockDown Browser + Webcam

Test 3 covers subject-verb agreements (20 questions; 20 minutes). If an original text contains an error, choose the one that corrects it; if it is correct, choose NO CHANGE. 

For example,

The number of people who shop online is growing.

• The number of people who shops online is growing.
• The number of people who shop online are growing.
• The number of people who shops online are growing.
• NO CHANGE

A singular noun "the number" should take a singular verb "is," but a plural noun "people" should take plural verb "shop." Thus, the correct answer is NO CHANGE.
