Please help will mark BRAINLIST!! How does considering perspectives found in text revise or broaden my thinking?

Read the speech from the play the importance of being earnest. algernon. you have invented a very useful younger brother called ernest, in order that you may be able to come up to town as often as you like. i have invented an invaluable permanent invalid called bunbury, in order that i may be able to go down into the country whenever i choose. bunbury is perfectly invaluable. if it wasn’t for bunbury’s extraordinary bad health, for instance, i wouldn’t be able to dine with you at willis’s to-night, for i have been really engaged to aunt augusta for more than a week. which responses clearly describe how a student who didn’t know the word invaluable could determine its meaning?
