Problem: Please answer a question about the following article about Florida:
From the 1930s through much of the 1960s, Florida was essentially a one-party state dominated by white conservative Democrats, who together with other Democrats of the Solid South, exercised considerable control in Congress. They gained federal money from national programs; like other southern states, Florida residents have received more federal monies than they pay in taxes: the state is a net beneficiary. Since the 1970s, the conservative white majority of voters in the state has largely shifted from the Democratic to the Republican Party. It has continued to support Republican presidential candidates through the 20th century, except in 1976 and 1996, when the Democratic nominee was from the South. They have had "the luxury of voting for presidential candidates who pledge to cut taxes and halt the expansion of government while knowing that their congressional delegations will continue to protect federal spending."
How does Florida vote in presidential elections 
A: continued to support Republican presidential candidates through the 20th century, except in 1976 and 1996, when the Democratic nominee was from the South
Problem: Please answer a question about the following article about To Kill a Mockingbird:
As children coming of age, Scout and Jem face hard realities and learn from them. Lee seems to examine Jem's sense of loss about how his neighbors have disappointed him more than Scout's. Jem says to their neighbor Miss Maudie the day after the trial, "It's like bein' a caterpillar wrapped in a cocoon ... I always thought Maycomb folks were the best folks in the world, least that's what they seemed like". This leads him to struggle with understanding the separations of race and class. Just as the novel is an illustration of the changes Jem faces, it is also an exploration of the realities Scout must face as an atypical girl on the verge of womanhood. As one scholar writes, "To Kill a Mockingbird can be read as a feminist Bildungsroman, for Scout emerges from her childhood experiences with a clear sense of her place in her community and an awareness of her potential power as the woman she will one day be."
What des Jem struggle to understand?
A: separations of race and class
