Remember the network at Candy-Workshop 3 of who follows whom:
- Anette and Bob follow each other.
- Anette and Charlotte follow Dan, who follows Bob.
- Emil and Greta follow Anette.
- Bob follows Frida.
- Hans follows Emil.
Keep in mind that if one elf follows another, the reverse does not necessarily apply. Also, if an elf follows another elf, it means that they take over the opinion of the elf they follow.
Elf Kristian from Candy-Workshop 5 finds himself in a tricky situation, as he got into Candy-Workshop 3 last night to get his hands on some of the new onion candy the whole North Pole is talking about. Just as he tried to sneak out, he heard a strange noise and is since worried that somebody has seen him.
Given that he is well aware of the news spreading network in Candy-Workshop 3, who should he ask in an inconspicuous manner whether something strange happened last night to maximise his chances to find out whether he has been seen?
a. Anette
b. Bob
c. Charlotte
d. Dan
e. Emil
f. Frida
g. Greta
h. Hans
