Consider the following question. It is a flawed argument (according to the LSAT). However, if "most" is logically equivalent to "at least one" then this argument would NOT be flawed. True?
PrepTest 15 Section 3 Question 22
In Sheldon most bicyclists aged 18 and over have lights on their bicycles, whereas most bicyclists under the age of 18 do not. It follows that in Sheldon most bicyclists who have lights on their bicycles are at least 18 years old.
Which one of the following exhibits a pattern of flawed reasoning most similiar to that in the argument above?
No, the flaw is the number
of 18 and older bicyclist vs. under 18.
There could be 6 of 10 w/lights on their bikes who are 18+
whereas under 18 w/lights could be 49 of 100.
The conclusion would be false, as most bicyclists w/lights are under 18 (49:6).
