PT70 Section4 # 17

For #17: Parallel Form

I got confused on how to diagram it (I understood everything except how to diagram (Note: the way I diagram for these is using broad A-->B,etc since the context isn't important but the form of the logic is):

The stimulus says that:

-some halogen lamps are well-crafted

-because halogen lamps from most major manufacturers are on display at FL

-and any item on display at FL is well-crafted

I wrote it as

some A-->B or A(--some-)B

A-->C

C-->B

But my diagram is wrong for:

because halogen lamps from most major manufacturers are on display at FL

it should be A(-some-)C

why is it some?

For #23:Parallel Flaw

like in #17 I had trouble diagramming a part of this stim.

The stimulus says that:

Almost every SP in the past had MTC

Using MTC to introduce VB

Therefore VB will be a SP

I diagrammed:

A-->B

B-->C

-----------

C-->A

But for "Using MTC to introduce VB" is suppose to be diagrammed as:

C-->B

Why? And why is my diagram wrong?

For #17: Parallel Form

I got confused on how to diagram it (I understood everything except how to diagram (Note: the way I diagram for these is using broad A-->B,etc since the context isn't impotrant but the form of the logic is):

The stimulus says that:

-some halogen lamps are well-crafted

-because halogen lamps from most major manufacturers are on display at FL

-and any item on display at FL is well-crafted

I wrote it as

some A-->B or A(--some-)B

A-->C

C-->B

But my diagram is wrong for:

because halogen lamps from most major manufacturers are on display at FL

it should be A(-some-)C

why is it some?

For #26: I understand why (E) is wrong because the stim. is not defending (never says if right or wrong) but I was just wondering if someone could explain the difference between context and fact (this is what confused me answer (D) says historical fact while (E) says historical context, I just wanted to get a better understand of context vs fact in case it shows up on another question then I can eliminate them even quicker) Thanks :)

I was between B/E and choose B because I immediately crossed out E b/c of the term HIGHLY productive which isn't stated in the stimulus (but E was right)

- can anyone explain this to me and also why E right over B Thanks :)

Hi I know that there are books that group the logical reasoning into question types but does anyone know of a book or other study material that has lsat questions grouped specifically by the type of flaw

EX.) the flaw: Absence of evidence-describes the flaw and then lists flawed lsat questions that are this flaw

do this for each type of flaw

(I feel this would really help me see how each type of flaw is used in a lsat question) -Thanks
