### HideShow timer Statistics

Jacques Leswift and Andy Flasch are the top two cyclists in the world and constantly compete for first place on the international road cycling tour. When Leswift is at maximum pace, his ratio of protein content to body temperature increases by 11.9% from its regular state. When Flasch is at maximum pace, the same ratio only increases by 8.6%. As part of a research project, the maximum pace ratios of a control group of moderately successful cyclists were measured and an average was calculated. Scientists compared the data and noted that a high ratio positively influences an athletic performance.

The statements above, if true, best support which of the following as a conclusion?

A) In general, Leswift achieves a higher athletic performance level than Flasch does as his maximum pace ratio is higher.
B) When compared, the average of the maximum pace ratios of Leswift and Flasch exceeded the average of the control group.
C) Statistically, Flasch has a lower chance of winning a cycling race against Leswift.
D) Leswift's regular state protein content to body temperature ratio is higher than that of the cyclists in the control group.
E) To reach maximum pace, the control group's ratio increased by a smaller amount than that of Flasch and Leswift.

Hello dina98

We have some numbers in this argument so it is better to make example with numbers
Cyclist A has initial ratio 100 and increase on 11.9% --> final ratio 119
Cyclist B has initial ratio 100 and increase on 8.6% --> final ratio 108.6

After measuring moderate control group scientists noted that a high ratio positively influences an athletic performance.

So we know that control group had lower ratio. For example their final ratio was 100
But what was its initial ratio? It could be 99 or it could be 20
In first case we have increase on 1% in second on 400%

A) In general, Leswift achieves a higher athletic performance level than Flasch does as his maximum pace ratio is higher.
Incorrect. We know nothing about "general" state of Leswift. He could have some fluctuations in his ratio

B) When compared, the average of the maximum pace ratios of Leswift and Flasch exceeded the average of the control group.
Correct. We know that final ratio of control group was lower than final ratio of two successful cyclists

C) Statistically, Flasch has a lower chance of winning a cycling race against Leswift.
Incorrect. We know nothing about statistic of their competetions

D) Leswift's regular state protein content to body temperature ratio is higher than that of the cyclists in the control group.
Incorrect. We know nothing about "regular" state of Leswift

E) To reach maximum pace, the control group's ratio increased by a smaller amount than that of Flasch and Leswift.
Incorrect. We know nothing about amount of increase. It can be 1% or it can be 400% as was mentioned in example above.

D) Leswift's regular state protein content to body temperature ratio is higher than that of the cyclists in the control group.
E) To reach maximum pace, the control group's ratio increased by a smaller amount than that of Flasch and Leswift.

I also selected ‘A’ at first but reading the argument multiple times made me realise that I was not correct.

Argument says few things:-
Facts- JL and AF are two top cyclists.
At maximum pace JL’s protein/body temperature ratio increases > AF’s ratio increase

A research was conducted of maximum ratio for moderately successful cyclists and average was calculated.
Scientists hypothesise that high ratio is directly proportional to high performance

A) In general, Leswift achieves a higher athletic performance level than Flasch does as his maximum pace ratio is higher. Look at the hypothesis result. It says that overall ratio is responsible for high athletic performance. We are given the ratio at only maximum pace and not at the minimum/medium pace. What if Leswift has different ratios all the while ranging between 1-11.9; whereas, AF maintains his maximum ratio throughout game. In this case AF’s ratio will be more than JL and he will have high athletic performance.
B) When compared, the average of the maximum pace ratios of Leswift and Flasch exceeded the average of the control group. Well, it is given that JL and AF are two top performers. Hence, their overall ratios will be more than the control group because control group is of moderate athletes. And JL’s and AF’s maximum pace ratio will certainly be higher than overall average ratio of control group.
C) Statistically, Flasch has a lower chance of winning a cycling race against Leswift. We are not talking about winning. We are just concerned about athletic performances
D) Leswift’s regular state protein content to body temperature ratio is higher than that of the cyclists in the control group. This choice talks about all the cyclists and not the average of control group.
E) To reach maximum pace, the control group’s ratio increased by a smaller amount than that of Flasch and Leswift. We are not given any such information.

Hope it helps.

The statements above, if true, best support which of the following as a conclusion?

A) In general, Leswift achieves a higher athletic performance level than Flasch does as his maximum pace ratio is higher. -We just know that the percentage increase in ratio is higher in case of Les than in case of Flasch. We don't the actual ratio so we can't comment on the athletic performance of the two.
B) When compared, the average of the maximum pace ratios of Leswift and Flasch exceeded the average of the control group. -Correct. Since the two guyz are winners, so their average should be greater than the average of the remaining cyclists.
C) Statistically, Flasch has a lower chance of winning a cycling race against Leswift. -Same error as in A
D) Leswift's regular state protein content to body temperature ratio is higher than that of the cyclists in the control group. -We don't know anything about "regular" state of the cyclists.
E) To reach maximum pace, the control group's ratio increased by a smaller amount than that of Flasch and Leswift. -Out of scope.

As part of a research project, the maximum pace ratios of a control group of moderately successful cyclists were measured and an average was calculated. Scientists compared the data and noted that a high ratio positively influences an athletic performance.

The statements above, if true, best support which of the following as a conclusion?

Premises:

1) JL and AF are top 2 cyclist and compete each other fiercely.
2) L Max Pace: P/BT increases by 11.9% from Regular state and for AF P/BT increases by 8.6% from Regular state
3) Research done and found out that high ratio positively influences an athletic performance.

Which means: if JL and AF are top 2 and high ratio positively influences an athletic performance, it indicates that JL and AF must have high ration compared to other average performer cyclist.

A) In general, Leswift achieves a higher athletic performance level than Flasch does as his maximum pace ratio is higher. Argument does not say that maximum pace ratio is the only factor for higher performance.Hence can not be concluded.
B) When compared, the average of the maximum pace ratios of Leswift and Flasch exceeded the average of the control group. Right.Hold On.
C) Statistically, Flasch has a lower chance of winning a cycling race against Leswift. Same as A. Argument does not say that maximum pace ratio is the only factor for higher performance.Hence can not be concluded. Chances of winning may depend on many other factors such as Technique, Skill, Strength Etc.
D) Leswift's regular state protein content to body temperature ratio is higher than that of the cyclists in the control group. No information about regular state protein content to body temperature ratio hence can not be concluded.
E) To reach maximum pace, the control group's ratio increased by a smaller amount than that of Flasch and Leswift. No information. Hence Wrong.

the last line of the stem concludes that a causes b , that is having a higher ratio helps in performing better.
But according to B, they have assumed the reverse, that is, being a better performer implies you have a higher ratio.

Correct Ans: B

In your explanation, you have assumed the reverse of a causes b to be true. But that cannot be taken as a guarantee
Could you explain how you got the answer as b

Hi rahulkashyap,

Few points on the question..
1) we are looking for the BEST ..
2) the para talks of two top cyclists and then average of all other moderately well doing cyclists, so our CONCLUSION has to be something to do with these two top cyclists and the average of others
There is no reason to get others in between the argument if nothing is being added about them. So remove all those are comparing these two top cyclists only.
3)the question talks of increase in ratio BUT finally the average is not of the increase but the Max pace RATIO.
4) it clearly mentions " Max pace RATIO POSITIVELY effects the performance.

So the BEST possible is B that their Max pace RATIO should be higher than others...

But I would also agree there could be other reasons and if I were to weaken this choice as a conclusion, I would talk of the other things too effecting the performance..

B
