By the end of the introduction, your reader should be able to understand what you are doing and why you are doing it. In other words, what is at stake ? Why should the reader read the essay? In the example above, readers might be interested to join you in working through the challenge presented in the last sentence, if they trust that you have thought enough about the challenge to lead them through it.
The third paragraph of the body should contain the weakest argument, weakest example, weakest illustration, or an obvious follow up to the second paragraph in the body. The first sentence of this paragraph should include the reverse hook which ties in with the transitional hook at the end of the second paragraph. The topic for this paragraph should be in the first or second sentence. This topic should relate to the thesis statement in the introductory paragraph. The last sentence in this paragraph should include a transitional concluding hook that signals the reader that this is the final major point being made in this paper. This hook also leads into the last, or concluding, paragraph.

These patterns can give a "lift" to your writing. Practice them. Try using two or three different patterns for your introductory paragraph and see which introductory paragraph is best; it's often a delicate matter of tone and of knowing who your audience is. Do not forget, though, that your introductory paragraph should also include a thesis statement to let your reader know what your topic is and what you are going to say about that topic.
During the Middle Ages in Europe and the Middle East there was much armed conflict between Christians and Muslims. Christians called these conflicts the Crusades because they were fighting under the sign of the cross to save the holy lands of the Bible from being desecrated by non-Christians. However, the true reason for fighting for these lands was less than holy. It was mainly a desire for economic gain that prompted the Christian leaders to send soldiers to fight in the Holy Land.
