Why has the American flag described in the poem became an iconic image used as tool for social justice and social change?O! say can you see by the dawns early light,What so proudly we hailed at the twilights last gleaming,Whose broad stripes and bright stars through the perilous fight,Oer the ramparts we watchd, were so gallantly streaming?And the Rockets red glare, the Bombs bursting in air,Gave proof through the night that our Flag was still there;O! say does that star-spangled Banner yet wave,Oer the Land of the free and the home of the brave?On the shore dimly seen through the mists of the deep,Where the foes haughty host in dread silence reposes,What is that which the breeze, oer the towering steep,As it fitfully blows, half conceals, half discloses?Now it catches the gleam of the mornings first beam,In full glory reflected now shines on the stream,Tis the star-spangled banner, O! long may it waveOer the land of the free and the home of the brave.And where is that band who so vauntingly sworeThat the havoc of war and the battles confusion,A home and a country should leave us no more?Their blood has washed out their foul footsteps pollution.No refuge could save the hireling and slave,From the terror of flight, or the gloom of the grave,And the star-spangled banner in triumph doth wave,Oer the Land of the Free and the Home of the Brave.O! thus be it ever, when freemen shall stand,Between their lovd home and the wars desolation,Blest with victry and peace, may the Heavn rescued land,Praise the Power that hath made and preservd us a nation!Then conquer we must, when our cause it is just,And this be our mottoIn God is our Trust;And the star-spangled Banner in triumph shall wave,Oer the Land of the Free and the Home of the Brave. what happened when john smith left jamestown Determine if this is a valid statistical question: What proportion of New Jersey residents would choose vanilla as their favorite ice cream flavor? * Which of the following is one of the steps for recognizing revenue?
