Can someone explain to me how answer B is the correct one? The sentence the question is asking concerns how cooking has impacted biological evolution; B is about domesticated animals and has nothing to do with cooking?

My score since June has been 161-165. During that time I went through the Trainer again (skimmed), did the Manhattan LR book, drilled individual sections time and untimed, foolproofed LG, and blind review everything I did. Today I took PT 67 and scored 164. What am I doing wrong and how should I approach my studying going forward? Many thanks!
