1) Well, models are vital to use by scientists, because that way they can represent visually and help other people understand the point they are trying to stress about their project.

Explanation:
This question is about "The Breadwinner"
Parvana needs to cut all her hair and although it left her unsatisfied in the beginning, she understands that this is the price she must pay to help her family and that hair is no more important than the family she loves. This is because Parvana lives in Afghanistan who lives under the Taliban regime, which oppresses and does not allow women's freedom. Parvana is primarily responsible for supporting the family and therefore needs to cut her hair and pretend to be a boy in order for the Taliban to allow her to continue working to support the family.
