The illustration and the story are the two methods used by the presenter to create the fact that volunteers are often selfish motivated.
Explanation:
The lecture shows how voluntary work travel expenses is a choice for younger people and adults that want to experience new voyages while helping people or animals who are in need, but it's not in fact so ethics it should be. The lecturer quotes a few histories to explain how volunteer work and voyage are a choice. He tells stories such as how many of their children are deliberately kept in poor shape to draw volunteers to come and invest their money.
He states, Mr. Dale Rofe is an ethical social worker, that "shrines and animal orphanages are sometimes created by volunteers to facilitate their abuse." He also tells that some volunteers who teach english, take photos of people who receive support, etc.
He also discusses with illustrations the various alternatives that even a person who wants to really help the disadvantaged, without traveling to unknown places such as visitors.
These examples include:
Donate one hour per week to shelter animals in your city, prepare monthly dinners for the needy and donate international organisations to the money you will use if you are worried about educating others.
Spend in books for individuals from various countries.
Maya Angelou does not let the standard meter, rhyme, and pase to control her poetry. She is the one who determines the structure or the lack of it and uses form to achieve what she wants. The sound, tempo, rhythm, and the rhyme are in service of each line. The poem “Caged Bird” is a great example of unstructured verse. The number of beats per line differs. The number of lines in each stanza changes as well. In addition, she uses the intermittent stanza as well. She also uses sporadic rhyme. The repetition of the third stanza serves to give some predictability to the poem and it draws the reader to participate with caged bird. Other parts of the poem are unpredictable. The joy of the free bird makes it possible for the reader understand the tragic story of the oppressed.
