I still have no idea how tf E was the correct answer choice. I don't see how food was ever mentioned in the stem, so therefore how could it be correct. Someone help!
Recently, I've found that breaking down the passage into logical components helps me understand it better. Although this process is time-consuming, reviewing the answer choices clarifies the flaws ONLY after I visually put everything in order, allowing me to visually identify the jumps on paper.
I got this wrong, but I'm now understanding what I ought to be looking for when working on sufficient assumption questions.
The shorter, more to-the-point lessons feel a lot better to absorb and follow; like, the max should be between 5 to 10 minutes instead of the 16-plus minutes, which overexplains and then overcomplicates our understanding.
Okay..... I'm giving myself a pat on the back because I GOT IT RIGHT !!!!!!!!
I got the timed section incorrect but took my time in the blind review and then got it correctly. Slow and steady wins the race when you are just starting out.
This was an amazing lecture I'd watch more of her lectures if there are anymore due to her ability to explain things so clearly.
I grasp the concept more with video lectures I'm not sure why this isn't the case for this giant section.
Here, we examine another formal argument pattern: if “most A are B” and “most A are C,” then we can conclude that “some B are C.” Last formal argument needed to be familiar with. Formal argument #6. This is called “two split most". This has to do with the generic form of the argument where it has to do with the generic form of the argument. Has to do with the shape of the argument. This is an argument where you get two premises that say [A most B]. So most [As are Bs]. Another premise that says [A most C.] So most [As are Cs.] When you have two premises that look like that, what must be true is that [some Bs are Cs.] There has to be a B and C intersection.
Premise: A - m → B - m → C
Conclusion: B ← s → C
A B, A B, A B C, A C, A C
Example #1: “Most almonds grown in California are produced for domestic consumption. Most almonds grown in California require intense irrigation. Therefore, some almonds produced for domestic consumption require intense irrigation.”
The conclusion follows logically!
If it’s true that most almonds are produced for domestic consumption, and it simultaneously is true that most almonds also require intense irrigation, well, there’s at least one intersecting almond that requires both intense irrigation and is produced for domestic consumption.
Premise/Chain Link: [Almonds - m → Domestic] [ - m → Irrigation]
Conclusion: [Domestic ← S → Irrigation]
RECAP:
Formal argument #6 “two split mosts”: Most As are Bs. Most As are Cs. Therefore, some Bs are Cs.
All arguments that instantiate this form are valid. We can substitute any concept for A, B, and C and the argument will still be valid.
Premise: [A - m → B]
[ - m → C]
Conclusion: B ← S → C
“Some cafes in the city serve hand poured single origin coffee.”
“Some” quantifies over the subject set “cafes in the city.” It pushes “some” members in that set over to the predicate set “serve hand poured single origin coffee.” city ← S → hpsoc hpsoc ← S → city The “some” arrow is reversibly read. (A ← S → B) ← → (B ← S → A) That means if it’s true that some cafes in the city serve hpso coffee, then it’s true that some cafes that serve hpso coffee are in the city.
“Most gold mines that supply unprocessed ore to Casterly Rock are running low on gold deposits.”
“Most” quantifies over the subject set “gold mines that supply unprocessed ore to Casterly Rock.” It pushes “most” members in that set over to the predicate set “are running low on gold deposits.” Gold Mines Supply CR -- m → Low on Gold Deposit “most” are not reversible!
“Many turtles swim across the Pacific to return to their hatching beach.”
“Many” quantifies over the subject set “turtles.” It pushes “many” members in that set over to the predicate set “swim across the Pacific to return to their hatching beach.”
If you want, you could translate “many” to “some.” I just want to make sure that you don’t mistakenly think that “many” turtles swim across…means that “most” turtles swim across because that's not true.
“Prof. Sprout’s Mandrake inspections are usually conducted on Mondays.”
The quantifier here is “usually.” We’re talking instances of Prof. Sprout inspecting her Mandrakes. “Usually” says that “most” of those instances are “Mondays.” Mandrake Inspection - - m → Monday Does this mean that on most Mondays, Prof. Sprout inspects her Mandrakes? No. Absolutely not. For all we know, she only inspects her Mandrakes ten times a year. Eight of those ten inspections are on Mondays. There are more than fifty Mondays in any given year. Be careful not to read ( A - - m → B) as ( B - - m → A)
“Fewer than half of the kittens adopted yesterday went to homes with children”
“Fewer than half” means “most not.” Fewer than half of the apples are rotten means that more than half of the apples are not rotten. The quantification is over the subject set - “kittens adopted yesterday” - and the “not” gets pushed onto the predicate set - “[not] went to home with children.” [ Kitten - - m → /Home -children ]
