In "We Wear the Mask," people suffer because life is painful and people hide their pain from the world. Dunbar writes the "clay is vile" beneath their feet, implying life on earth is hard and difficult. They do not change their situations because they cannot -- it is implied that to live is to suffer. In the poem these people appeal to Christ to save them.
In "Sympathy," the bird suffers because it is caged. It sees the beauty of the world around it but it cannot participate in it. The bird cannot change its situation because it is literally imprisoned. The caged bird appeals in its pain to Heaven, hoping God will relive its suffering.
Context clues??? i don't if im right sorry
The action of the speaker that can be considered ironic is that actually the speaker takes initiative of establishing the wall up to himself but then he questions it and has some doubts about that. There is another irony, I would say, the main one, you may find it useful : the wall which was meant to separate neighbours brings them together every year in order to repair it. Is it really the borderline?Hope that helps.
The answer is letter a. The Olmec culture is recalled today in part because it was the first Mesoamerican culture to build small cities, most particularly San Lorenzo and La Venta. It was said there were an abundant rainfall and seasonal flooding within the site the Olmec Civilization in those places.
