My first paragraph

In both The Lion and the Jewel and Things Fall Apart, the sudden cultural changes were brought about by the intrusions of other cultures. The intruding factors in The Lion and the Jewel came more from the foreign propaganda that was spreading throughout the Ilujinle tribe, causing some members of the tribe to begin changing theirs beliefs. The school teacher, Lakunle, was an example of this when he began reading books and not going along with some of the tribe's traditions. Sidi, the village belle, became completely infatuated with herself when the intruding photographer put her pictures in a magazine, causing her to forget some of the old ways. The magazine itself was brought in by people foreign to Nigeria, and it caused the tribe to act in unorthdox ways. In Things Fall Apart, there were more personal intrusions, where the white men physically came to their villiage and brought Christianity to the people. Nwoye, Okonkwo's son, is an example of one of the tribe members who was converted out of the Igbo lifestyle. The foreigners caused anger among those who were not swayed by the Christian belief, and violence broke out because of this anger. Also, one of the strongest men in the tribe, Okonkwo, was driven to killing himself because of the forceful impact the missionaries had.

Also, I have a question for you Ms.MacDonell. When there are book titles in your essay, how are you supposed to write them? Do you underline them or put quotations around them or what?
