A commonly accepted myth is that left-handed people are more prone to cause accidents than are right-handed people. But this is, in fact, just a myth, as is indicated by the fact that more household accidents are caused by right-handed people than caused by left-handed people.
The reasoning is flawed because the argument
(A) makes a distinction where there is no real difference between the things distinguished
(B) takes no account of the relative frequency of left-handed people in the population as a whole
(C) uses the word “accidents” in two different senses
(D) ignores the possibility that some household accidents are caused by more than one person
(E) gives wholly irrelevant evidence and simply disparage an opposing position by calling it a “myth”

The flaw is the argument is that:
1. The argument uses only one subset of data that is household accidents and generalizes it to all accidents.
2. The number of left handers and right handers is not mentioned.
For example if 10000 right handers commit 1000 household accidents, then that is only 10 percent. But if 50 out of 100 left handers commit household accidents then that is 50 percent.
A. There is definitely difference between the things distinguished. Incorrect.
B. Correct. This simply says that the number of left handers commiting the accidents is not mentioned.
C. This is very tricky. This is close to our prethinking. But note that it says using accident in two different senses. That is not what we want. We want that one set of household accidents has been used to represent all accidents. That is not what this choice says.
D. How does that matter. Totally irrelevant.
E. The evidence is not irrelevant. It is just flawed.
B is correct.

The argument doesn't tell about the ratio of left-handed and right-handed people. If there are 80% right-handed people and 20% left-handed people then the number of accidents caused by right-handed people will be more even if a lot less % of right-handed people are causing them. Only option (B) aligns with this pre-thinking.
