Verbal | Re: new information in CR answer choices - when

Hi,

Iv'e recently noticed that I have same mistakes in CR questions, regarding the use of new information, that was not part of the argument, in the answer choices.

for example: questions 555 and 664 (OG 2017) are bothconstruction type - however 555 uses new information in its answer, while 664 official explanation says that new information cannot be used for the right answer.

I'll be very thankful if someone can explain when the use of new information in the choices is "forbidden".

also,
