Hi @connordelacruz,

Thanks for the question! So let’s take a look at the format of this question. I’ll diagram it out really quickly:

Files tax return on time —> Accountant prepares & Accountant doesn’t ask
Conclusion: No file on time

To make this a bit more abstract:

A —> B & C
B —> ~C
Conclusion: ~A

(B) tells us that Tovah can’t attend a concert if away on business. If she misses the concert, she can’t attend another one this month. She’ll be away on business, so she won’t attend a concert this month.

Away on business —> Cannot attend next week
Cannot attend next week —> Can’t attend this month
Conclusion: Can’t attend this month

Or:

A —> B
B —> C
A
Therefore: C

(C)’s diagram tells us:

~Play video games —> Not content
Play video games —> No other activities planned
~Break from planned activities —> Not content

Or:

~A —> B
A —> C
Conclusion: C —> B

(D)’s diagram tells us:

Not seated first class —> seated business class
Not seated first class
