Paraphrasing (3rd paragraph)
Text
But I traveled to Quebec for the real show; the "People's Summit", an alternative event organized ostensibly to represent—what else?—the "people's views." (I had assumed that the elected leaders at the Summit were there for that purpose, but who am Ito question "the people"?). The Hemispheric Social Alliance, a coalition of ideological and economic interest groups that are opposed to free trade, had invited fringe groups, from the far-left to the farther-left, to a "carnival against capitalism" in a big white tent alongside the river. Gracious to a fault, the Canadian government (i.e. Canadian taxpayers) funded the event and paid for Latin American activists to attend.
The main idea of the paragraph
But the author was more interested in the "People's Summit", the demonstration outside the Summit of the Americas by those who were opposed to free trade.
但是，作者对“人民的高峰会议”更感兴趣，对由那些反对自由贸易的人士在美洲国家高峰会议外进行的示威游行感兴趣。
