Answer:
Hi! The passage from The Role of Social Media in the Arab Uprising, by Heather Brown, Emily Guskin, and Amy Mitchell that provides more effective evidence is the third one:
The first passage provides more effective evidence
because it has data and statistics from research
reports, while the second passage uses titles of articles
and authors' names as evidence.
Step-by-step explanation:
I chose the third option because the first passage is the only passage that gives objective information and the one that bases this information in an official report published by the United States Institute of Peace, which is a formal, reliable organism. The second one based its information in the Pew Research Center's Global Attitudes and its articles from authors that are not the official source pertinent for these matters. That is why I chose the third option. all regions equally.
