How do you represent neither nor ?

https://classic.7sage.com/lesson/visual-representation-of-or-and-not-both-in-inout-games/

Basically, my issue is with the whole explanation from JY. But for discussion sake let's focus on Q23.

If you read the question paragraph or question stem without reading Q23, you will figure out that J and K are bidirectional i.e. cannot be in the same clinic together (proof below).

So my question is why is then Q23 can have A too as the right answer choice.

Proof

s and r are locations

Js -> Kr

~Kr -> ~Js

Ks -> Jr (because only s and r are there)

Therefore, Ks (-) Jr

Stmt: Either A or B is in the forest

Question: Is "either or" and "exclusive or" here ?

My Answer:

No, because atleast 1 has to be there but not both.

A B not both

0 0 0

0 1 1

1 0 1

1 1 0

My Discussion:

"Either or" is different than "not both" because "not both" truth table is below.

A B not both

0 0 1

0 1 1

1 0 1

1 1 0

Notice the 1st line is different in both truth tables.

Question for you guys:

please see if my logic is correct

Q7 here:

Are "noth both" and "neither nor" equivalent?

I am trying to figure out exactly how long the exam will be. If your reporting time is 12.30 and test is 3h 30 mins per website shown below, then does it finish exactly at 4pm or after ? I am have to make another appointment after so I asked.

Hi,

Since you probably have to uber back and forth to the test center, are cellphones allowed and can be kept outside in some locker ?

Can you take LSAT writing on the day of the exam ? I am assuming the link is available at midnight.

Is it possible to take the exam in the exam center ?

How many games appear on any section ? A quick glance shows not more than 4 games which should total 23-24 questions.

Question:

How do you tell schools to not look at your file until you appear for the Jan 2020 LSAT i.e. ignore your scores so far ?

Seems like CAS will report every score after it is available but the school might not know you registered for a future LSAT and might give a decision without considering your future LSAT score.

I want to challenge in the following example ( https://classic.7sage.com/lesson/basic-translation-group-1-flashcards )

Each and every member of Q is omnipotent. Lecture tells us M is SC and O is NC.

However, if we use venn diagram (from set theory) and sorry for the long explanation but I cannot post pictures or draw here.

it raises questions.

Q1: Out of M or O, which "IS" the bigger set ? A1: we do not know

Q2: Out of M or O, which "cannot" be bigger than the other ? A2: M cannot be bigger than O because .... "Each and every member of Q is omnipotent" but are all omnipotent set members members of Q ? Obviously, not necessarily .

Well if Q2, A2 is right than why is O not the SC and M the NC ( not by logic but because whatever is left should fit in the remaining slot )

Most videos including one below show a chart : where is the complete chart
