Which one of the following is an argument that contains flawed reasoning most similar to the flawed reasoning in the argument above?
(A) Bill claims that soil can be damaged if it is tilled when it is too wet, and Sue claims that seeds planted in wet soil can rot. Therefore, if both claims are true, gardeners who till and plant their gardens when the soil is wet damage both their soil and their seeds.
(B) According to Sara, most children like pies. According to Robert, most children like blueberries. So if Sara and Robert are both right, it must be that most children like pies that contain blueberries.
(C) Mark will go on a picnic today only if it does not rain. Susan will go on a picnic today only if Mark goes too. Since it is not going to rain today, both Mark and Susan will go on a picnic.
(D) The majority of customers who regularly eat at this restaurant always order both fish and stuffed mushrooms. Thus, fish and stuffed mushrooms must be the restaurant’s most frequently ordered dishes.
(E) Most people living at Gina’s house cook well. Since most people at Gina’s house enjoy eating well-cooked meals, most meals served at Gina’s house are cooked well.
The stimulus contains two parallel events. The author concludes that since the two are parallel events, they must be related to each other.
Only B showcases such a flawed reasoning.
E is incorrect because the intent with which the conclusion draws basis on the premises is not equal to that of the question. But still, E is also a good choice but B is far better.
In reasoning questions, the best way is to understand the argument. The stimulus contains three "most"s, so any full "certainity" in any of the choice is wrong. A and C are wrong.
D introduces another kind of reasoning and hence incorrect.
