Influencer is a new and trendy profession and for sure even elves are on social media and spread the news among themselves. At Candy-Workshop 3 there is an interesting network 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.
A new elf, Ingrid, arrives at the workshop and wants to make sure her campaign on introducing red onions as the new Christmas Sweet Special is successful by launching a social media campaign. If Ingrid can only convince one co-elf to follow her, who should that be to maximise her impact?
a. Anette
b. Bob
c. Charlotte
d. Dan
e. Emil
f. Frida
g. Greta
h. Hans
