Quote:
Fava beans are an important ingredient of many vegan dishes, as they are rich in iron and other essential minerals. Unfortunately, fava beans also contain many oxidants, which, in large quantities, are very dangerous to people at risk of hemolysis, as these oxidants promote the development of blood disorders. As such, some chefs have replaced the fava beans in their vegan dishes with alternative sources of iron and now claim that people at risk of hemolysis who would like to eat their vegan dishes can do so without worrying about developing a blood disorder.
The chefs’ argument assumes which of the following?
Fava beans -- > risk of hemolysis
Remove fava beans means remove the risk of hemolysis?
Conclusion: people at risk of hemolysis who would like to eat their vegan dishes can do so without worrying about developing a blood disorder.
Find strengthening options to conclusion:
A. Blood disorders caused by carbonizers, which are close relatives of oxidants, can be prevented by removing the carbonizer-containing food.
Irrelevant: We are more interested to know details about oxidants in many fava beans.
This option won’t help much in strengthening the conclusion.B. The alternative ingredients maintain the iron and mineral content of the vegan dishes without adding oxidants.
We are more concerned about alternate resources that replace fava beans. Not about alternate ingredients.
This options looks good at first.
But reading closely , makes it irrelevant.C. Removing the fava beans will remove all the oxidants from the vegan dishes.
Seems strengthened at first. Lets see
Negate : Removing the fava beans will
not remove all the oxidants from the vegan dishes.
What if small quantity is left, still it is not dangeours.
What if 99% quantity is left ( because didn’t remove all) . then it is dangerous.
So negate of this option doesn’t destroy the conclusion.Moreoever, this option doesn’t cover scope of other sources. We can not rely only on fava beans for oxidants resources, unless mentioned,
D. The chefs’ vegan dishes do not contain significant sources of oxidants besides fava beans.This option directly hits at conclusion. What if there are other sources then removing fava beans is not helpful.
On negate: The chefs’ vegan dishes
donot contain significant sources of oxidants besides fava beans.
Oh then this option destroys the conclusion.
Seems correct answer.E. People at risk of hemolysis require additional sources of iron in their diet.\
This option
doesn’t help much in strenghrening the conclusion as it doesn’t talk about oxidants in fava beans.
Final answer:D
