How do you identify Pin 1 based off these pictures?
I expect this to be a typographical error. They used the wrong picture to illustrate the question.  In this case they used the same picture as the one used in question 2-28. The questions 1-36 and 1-37 have good images to identify the pin1 and I assume something similar was intended for the question 1-35.

A pdf version of the book is this, and question in case is at page 162.
