A number of exam takers, including myself, think the correct answer is answer 3,however answer 3 on question 20 receives immediate feedback of "incorrect".
Several others who took the exam commented on this here https://courses.cognitiveclass.ai/courses/course-v1:CognitiveClass+DA0101EN+2017/discussion/forum/course/threads/5bfd72a9b88a9d0690000412 .
If #3 is not the correct answer, can someone please provide an explanation of what is the correct answer and why, please ?C.A. supported this idea ·
