The reasoning in the salesperson’s argument is vulnerable to criticism on the grounds that it fails to consider the possibility that
(A) salespeople who have spent three years developing a client base might not yet be successful in sales
(B) some salespeople require fewer than three years in which to develop a strong client base
(C) a salesperson who has not spent three years developing a client base may not succeed in sales
(D) it takes longer than three years for a salesperson to develop a strong client base
(E) few salespeople can afford to spend three years building a client base
EXPLANATION FROM Fox LSAT
Rearranging the argument, it goes like this: To succeed as a salesperson, one must first establish a strong client base. And studies have shown that anyone who spends at least three years developing a client base can eventually make a comfortable living in sales. Therefore, all successful salespersons have been in sales for at least three years.
I’m not buying it. The problem with this logic is that it has confused a sufficient condition with a necessary condition. According to studies, it is sufficient that if you spend three years developing a client base, you’ll make a comfortable living in sales. But that doesn’t mean that
every successful salesperson has spent three years developing their client base. It’s not necessary.
Why isn’t it necessary? Well, imagine what will happen to Tim Tebow as soon as he inevitably washes out of the NFL. You know that guy is going to be selling cars, don’t you?
Of course he is going to be selling cars. And he’ll probably be quite successful right off the bat, selling gigantic trucks to his built-in fan base of homeschooled Christian college football nut jobs in central Florida. He won’t need to spend three years developing a client base. They’ll come flocking to him.
The flaw in the argument was confusing a sufficient condition (spending three years) with a necessary condition.
A) The argument doesn’t claim that you’ll be successful immediately as soon as you put in your three years, just that you’ll “eventually” be successful. And anyway, this isn’t what we’re looking for. We’re looking for, “Fails to consider the possibility that someone might be successful in sales without spending three years building a client base.”
B) Tebow! This is our answer.
C) The argument actually assumes this. If you’ve assumed something, you haven’t “failed to consider” it.
D) The argument mistakenly assumed that everyone needs at least three years. The argument didn’t fail to consider that salespeople need more than three years.
E) This just isn’t relevant.
Our answer is B, because it points out the possibility that Tim Tebow might be a successful car salesman without needing three years to build his client base.
