What book?? next time u should include the book & more info . that’s prob why no ones answering .
For this one, i would say B, because we are all good at our own things and to base ur career on other people isn't the best idea. Pick something ur good at and will enjoy!
-hope this helps :3
Choose which word in the brackets best fits the sentence/sounds better for example for the first one, what would be better: everybody MAKE mistakes or everybody MAKES mistakes?
