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