(B) If Maria trained hard, she would win the sailboat race.

(C) Maria could beat a four-time winner only if she trained hard.

(D) If Sue trained hard, she would win the sailboat race.

C it is .
Use of word "only if" .
If there are more reasons other than hard training when Maria can beat sue then we cannot conclude that training hard is the only reason for Maria's win

B is a trap and weakens the argument.
C is the answer.

Maria won this year’s local sailboat race by beating Sue, the winner in each of the four previous years. We can conclude from this that Maria trained hard.
The conclusion follows logically if which one of the following is assumed?


This is a CAUSAL RELATIONSHIP-----
Assumptions- Training hard ONLY led to Maria's win.......
Nothing else led to Maria's win



(A) Sue did not train as hard as Maria trained....cant say what applies for Sue... we only know what applies for Maria.
(B) If Maria trained hard, she would win the sailboat race.....cant say about future..... this time she won because she trained hard...WOULD does not invoke a total sence of certainty.....
(C) Maria could beat a four-time winner only if she trained hard..... .... Training hard ONLY led to Maria's win.......
Nothing else led to Maria's win.....correct

(D) If Sue trained hard, she would win the sailboat race..... ..cant say what applies for Sue... we only know what applies for Maria.
(E) Sue is usually a faster sailboat racer than Maria.......not an assumption.

IMO "C"...............

KUDOS IF YOU PLEASE............

Agree with C.

If X happens than Y will happen;

here it only works in one direction.

therefore, if Y happens, than X did not necessary happen too.

Answer C.

not thAn, thEn dear :-D

Otherwise, C as well. This is the conditional clause that validates the conclusion without a doubt.

Now let's look at B vs C.

B) If Maria trained hard, she would win the race.

Does this prove that Maria MUST HAVE trained hard? No - just because training hard is one way to win the race doesn't mean that it's the ONLY way to win the race. For example, maybe Sue broke her leg at the starting line. Since (B) doesn't eliminate other possible paths to victory, it doesn't PROVE the conclusion.

C) Maria could beat a four-time winner ONLY IF she trained hard.

Well, we know that Maria beat Sue, a four-time winner. If we add in a new piece of evidence that the ONLY WAY to do so is to train hard, then it MUST BE TRUE that Maria trained hard. Accordingly, (C) proves the conclusion.

Okay ! so the contention of doubt is between B and C.
Before that, always remember that winning does not necessarily mean that the person has worked hard, may be the competitor gave up or was not prepared.

B: "if" .. This is a mistaken reversal of what is needed. We know this, but does it necessarily mean that she worked hard? If leads us to a probabilistic situation
C: Adding this choice to premise takes us to the conclusion.

For anyone wondering, this is actually an LSAT JUSTIFY question, and NOT an assumption question. The OA is correct, but it is worth pointing out in case there is any confusion moving forward

Conclusion: Because Maria trained hard, she could beat Sue, who was champion for 4 years.

Assumption: If Maria did not train hard, she couldn't beat Sue in the race.

(A) Sue did not train as hard as Maria trained. - Negating this statement does not break conclusion.

(B) If Maria trained hard, she would win the sailboat race. - Cannot tell about this based on given premise.

(C) Maria could beat a four-time winner only if she trained hard. - Yes, clearly the assumption.

(D) If Sue trained hard, she would win the sailboat race. - Cannot comment on Sue from given Premise.

(E) Sue is usually a faster sailboat racer than Maria. - We cannot comment who is fast from the given premise.

Option C is correct. But how do I eliminate option B.

Negation of B
If Maria didn't train hard, she would win the sailboat race.
So this breaks the conclusion that Maria trained hard.

Please clarify my doubt.

I didn't understand clearly, say if there was an option choice which stated Maria trained hard, so she will win the race would this be the right answer. how do I use negation technique to eliminate between B and C?

Thank You :)
