Hello there ☺️,
In my opinion, Anna's father might have bought the skull, so as to get money from the government to earn a living for him and Anna.
Most probably, he might have been so poor that he had no there option, but to make some money for their survival by saying that he got a crystal skull, which everyone thought was a relic from the last.
He didn't hide it, but was afraid that Anna might tell the secret . So, Anna's father had cooked up this story, which is fake.

I'm almost positive the answer is: "It will help organize the flow of ideas". I hope I helped! :)
The topic which best completes the idea web is the following one:
Value of volunteering.
When volunteering, one gets to meet new people and could make friends with them. It is also an accomplishment, since volunteering is a way to actually do something concrete. It also leads to satisfaction because being able to help is a source of joy. Besides, volunteering is a way to improve one's community, since the whole idea of it is making something better by offering help. Therefore, the idea web shows what volunteering can bring and do. In other words, it shows its value.
