This question is based on the following poem.
Laugh and be merry, remember, better the world with a song,
Better the world with a blow in the teeth of a wrong.
Laugh, for the time is brief, a thread the length of a span.
Laugh and be proud to belong to the old proud pageant of man.
(Laugh and Be Merry/John Masefield/Public Domain)
Which of these is the main idea of the poem?
