for number one) i would say that it would have to be either be 50% because its a 50-50 question if not that idk what is the answer then LOL
for number two) I've actually heard this one before it s NIGHT and DAY because a new day and then night is born (already knew the answer)
for number three) THIS ONE IS SO TRICKY!!
after reading this multiple times over i noticed the riddle is in 3rd person and it threw up red flags because it meant the person was watching the girl while she was being murdered it also says the key words "she kills her sister" SHE WAS THE KEY WORD..... meaning that the sister killed her :(
LAST ONE WAS SUPER HARD!!
