Critical Reasoning

I go by the books:

my answer is A because generally in a parallel reaosning question always try and parallel 3 elements:

1. the validity of the argument
2. the conclusion
3. the premise

in this order

Also if you look at option A the author arrives at the conclusion based on a past action

Hence we have to choose an answer that indicates the effect now based on an action of the past( which is advertising in a newspaper)

MY ANSWER - D
