[potatoXfries]

(1)If Semenov is involved in the crime, then Bykov is also involved.
(2)If Alexandrov is guilty, then Bykov is also guilty

[Uncle Iroh]

q = Semenov is involved in the crime
p = Bykov is involved
r = Alexandrov is guilty
s = Bykov is guilty

1. q -> p
2. r -> s

not sure if ganito, pero parang ganyan ata yan
