Quantifiers

I was leaning towards the correct answer about automobiles, but I realized the quantifier in the question stem was "some" as opposed to "most" that was found in the question. That's what threw me off. In the lecture, it said to focus on whether it's flawed/valid and the structure (S&N terms, quantifier terms...etc). Can I get clarification on this, please?

There is a mistake in the explanation:
In the answer choice explanation it says:
"Stimulus Summary: Some games are competitive and have rules; others have neither. Thus, competition and rules are necessary for something to be a game."

The stimulus conclusion is : competition and rules are NOT necessary for something to be a game.

It's kosher for minor elements to change, as long as the overall argument remains intact. Here the most and the some do the exact same thing in both cases- they tell us that a subset of a general set have some trait, but another subset do not have that trait. This is the core of the argument, and from this we can conclude that since there are some members of the set that lack the trait, the trait is not essential to the overall set.
