Remember that in a persuasive speech the author, in this case Ian, is trying to persuade an audience to accept an idea, attitude, or action. To do so, argumentation, rationalism, symbolism, and the usage of supportive information is needed. In this case Ian uses his own experience to support the idea that learning foreign languages is very important to the student's education. By telling this, the audience can infer that if it was helpful for him, it can also be for other students. He appeals to logos, clearing out how and why the foreign languages are essential.
