Based on the passage, it can be concluded that the author and Broyles-González hold essentially the same attitude toward

Because of the quantifiers that also appear in these statements which takes them out of the S & N realm.

For example, "Only a few always do their own research before investing."

While this does have "only" it is not a S & N statement due to the presence of "few."

Hope that helps!

Hey, so I can get all the contrapostives from the drill practice I can get the premise contrapostives and the conclusion contrapostibes but I still don't know how to get the missing premise ?
example
d ->a
c->d
missing premise ? comes from where
Not x->a

@sigmajonez14,

Great question. Let's take a look.

D - >A (not A - >not D)
C - >D (not D - >not C)
:
Conclusion: Not X - >A (not A - >X)

We need to add a premise that allows us to chain everything up.

not A - >not D - >not C

We need to go from not A - >X, so if we add not C - >X, we can arrive at
our conclusion.

The missing premise is not C - >X (not X - >C).

Does this make sense? Let us know if you have any questions!

on the missing premise do we just put in X
from the contrapostives could it be not a ->not d->not c->x

basically you are just working from the contrapostives and trying to link the first cp with the last and link them

@sigmajonez14, right. We look at the original and the contrapositive for each premise and the conclusion and figure out how to best chain it all together.
