A student recently wrote us: "Something is wrong with this answer explanation. A and B can not both be wrong."
For roman numeral questions on the MCAT, some answer choices can have one of the correct options but does not include all the correct options. To get these questions correct, one needs to select the answer choice that includes all of the correct options. Any answer choice that does not have all of the correct options will be an incorrect answer even if it includes one correct option. Although answer choice A includes a correct option, it does not have all of the correct options. That is why "A" is incorrect. B includes a wrong option and is, therefore, incorrect.
Thanks for your question. I hope this helps!
