So I chose A correctly during my timed test and changed to B

My initial line of reasoning was correct. The term "FEW" implies that only a small portion of them had the breakfast.

I was confused, however. Since few could also be read as "some of them did eat breakfast" in some situations.

But there is a difference between "some" and "few"

Few implies a small fraction of people. And if ONLY FEW had breakfast from Group B, it reaffirms that it is the breakfast that caused the productivity increase.

I changed my answer from B -> D because

I wasn't sure how Commercial Viability related to "Interest of Competitors"

Because I thought commercial viability had to do with consumers, not manufacturers

But looking back at it, Commercial Viability is how well a product does in the market.

Of course this will be in the interest of Competitors to have their products do well in the market.

I think you are correct

I totally misread the Stimulus.

They only mention CONCENTRATION

NOT THE TOTAL AMOUNT

So even if you dilute it, if you dump it all, the TOTAL AMOUNT would be the same regardless

I mistook the premise: I assumed that after diluting, they also limited the total amount as well.

Because what is the point of diluting if you just dump all of it anyways? -> this was the flaw.

Premise 1:

Calcium Deficiency -> Rise in Blood Pressure

Deficiency Vitamin D -> Calcium Deficiency

Premise 2:

Calcium in Milk CAN make up for Calcium Deficiency

Conclusion: SOME older people can Lower Blood Pressure by drinking milk

Possible Assumption: Some older people can get enough Vitamin D to absorb Calcium from milk.

B and C are wrong because:

Merely saying that it’s not going to screw things even more isn’t going to make the conclusion of "older people lowering blood pressure" valid.

B and C are Necessary but not Sufficient

D is irrelevant -> “people who consume” =x= “some older people with high blood pressure”

E is irrelevant -> If they BOTH have these deficiency, then how does it explain how older people lower blood pressure by drinking milk?

Correct Answer: A

A) There IS milk that older people can utilize, with enough Vitamin D to absorb Calcium.

Having milk that allows these people to absorb Vitamin D to absorb calcium, and the fact that the milk can make up for the calcium deficiency allows the conclusion (some older people lower blood pressure) to be valid.

Premise: FAR MORE citations during school than when students are out of town

Conclusion: MOST citation issued to students

Shift in Language: Far More =x= MOST

Flaw:

There may be more citations, but what about citations related to people who are NOT students?

There may be 5 vs 100 citation difference for STUDENTS

But there may be 1000 citation issued to Non-Students (Vendors, Teachers, Residents, etc)

The conclusion MAY be true, but it also MAY NOT be true

Crossed Out:

B) “More -> More (Greener)”

The stimulus goes from More…. To MOST

C)

Most University People -> Studious

Most Studious People -> Go to University

The total people who go to university may be 1000

The total Studious People may be 100

Logic goes from Most -> Most.

D) Different type of flaw.

More Variety =x= More Total

Left with A vs E

A)

Conclusion: Children buy MOST SNACKS

Premise: POPCORN sale increase as children proportion increase

Popcorn =x= Snacks in general

This is closer to answer choice (D) in terms of single kind of snack vs total snacks.

Answer: E

E)

Conclusion: Most snacks parents buy go to other children

Premise: When other children visit, MORE snacks than usual

MORE snacks than usual when other children visit -> MOST snacks to other children

There is a parallel between citation vs snacks. And students vs other children.

I really wish the explanations went beyond "that's just...that's just... terrible argument"

What's the point of a teaching program if the instructor just brushes off each question/answer choice as "obvious"?

I'm here to learn, not to be told that I suck at logic. If it really is that easy/far-off from the answer, maybe explain why/how?
