							Hi,
I was stuck between answer choice A and B on this question and ended up choosing B. I understand how A is correct in that the property of being patterns of electronic signals is shown to have a positive result but also a possible negative result and that would therefore lead to answer choice A. However, I am still confused as to why exactly B is wrong because the two answer choices seem very similar to me. Thank you!
