Final answer:
Tusia's statement about Gerda refers to a renewed sense of faith in people. Whether Gerda's decision to create good news is positive depends on the impact of that news on the receivers' emotions and expectations. Literature offers profound value, but its potential gifts are often underappreciated.
Step-by-step explanation:
When Tusia says that Gerda has given her "belief in humanity," she is expressing a renewed faith in people's goodness because of Gerda's actions or words. Gerda's response is not specified in your provided information, so I cannot confidently report on that.
As for Gerda's decision to make up "good news" for the other girls, whether it's a good decision depends on one's perspective. If it provides comfort and hope in dire situations, it might be seen as positive. However, if it raises false hopes that could lead to greater disappointment, one might view it as unwise.
Literature often holds a mirror to society and provides insight and wisdom that can influence one's view of the world. When Tusia says few people ask from books what books can give us, she might be implying that people are unaware of the deep value and potential impacts that literature can have on personal growth and understanding of life and society.
