If, in a tennis tournament, a match reaches a fifth-set tiebreak, the lower-ranked player always loses the tiebreak (and, therefore, the match). If Rafael, the second-ranked player, wins a tournament by beating Roger, the top-ranked player, then the match must not have included a fifth-set tiebreak.

Which of the following arguments most closely mimics the reasoning used in the above argument?

(A) If a woman with a family history of twins gets pregnant three times, she will have one set of twins. Jennifer, who falls into this category, had two sets of twins, so she must not have gotten pregnant exactly three times.

(B) If a salesman sells more product than anyone else in a calendar year, then he will earn an all-expenses-paid vacation. Joe earned an all-expense-paid vacation, so he must have sold more product than anyone else for the year.

(C) A newspaper can charge a 50% premium for ads if its circulation surpasses 100,000; if the circulation does not pass 100,000, therefore, the newspaper can't charge any kind of premium for ads.

(D) If a student is in the top 10% of her class, she will earn a college scholarship. Anna is not in the top 10% of her class, so she will not earn a scholarship.

(E) All of the players on a football team receive a cash bonus if the team wins the Super Bowl. If quarterback Tom Brady earned a cash bonus last year, he must have been a member of the winning Super Bowl team.

Question: A = fifth set tiebreak B = low rank player lose

If rafael wins = not B then no fifth set tiebreak = not A

If A then B, if not B then not A

a) A = family history of twins get pregnant 3 times B = one set of twins Jennifer had two set of twins = not B not have gotten pregnant three times = not A If A then B, if not B then not A this is the answer

b) A = sells more product than anyone else B = vacation If A then B, if B then A so out

c) A = if circulation > 100k B = charge 50% premium If A then B, if not A then not B also out

d) A = top 10% in class B = scholarship If A then B, if not A then not B out

e) assumption is based on all the players receiving cash bonus and not just an individual out

Try it yourself and then see the explanation below !!!

Answer (A)

The structure of the argument is

If, A [in a tennis tournament, a match reaches a fifth-set tiebreak,] then B [the lower-ranked player always loses the tiebreak (and, therefore, the match)]. If NOT B [Rafael, the second-ranked player, wins a tournament by beating Roger, the top-ranked player,] then NOT A [then the match must not have included a fifth-set tiebreak.]

So, we are looking for a structure similar to If A then B. If not B, then not A.

Answer 1 most closely matches the structure If A then B. If not B, then not A.

HOPE This helps !!!

choice is between A,C and D.

C and D are exactly the same. A differs in the point that as the second seeded player wins the match,so too the mother has two sets of twins rather than not being in top 10% as in D or not selling past 100k mark.

Thus A scores at this.

Notice tha there is a flaw in the reasoning of the original argument: The statistics of the past will determine what will happen in the future. But we know that that's not true. The rest of the arguments don't have that flaw. Most of them have a cause-effect argument.

If A --> B

If Not B --> Not A

On the same line, If a woman with a family history of twins gets pregnant three times -- A she will have one set of twins -- B

Jennifer had two sets of twins -- Not B

so she must not have gotten pregnant exactly three times -- Not A

The key point in the structure is

If X happens then Y happens to Rafael, i.e. he loses. Rafael did not lose, therefore, X must have not happened.

Only option A has the same structure, i.e. If somebody in a family gets pregnant three times (X) then one pair of twins happen(Y). Jennifer did not have one pair of twins (she has 2) so she must not have got pregnant 3 times (X must not have happened).
