Question: The passage given below is followed by four alternate summaries. Choose the option that best captures the essence of the passage.
Social movement organizations often struggle to mobilize supporters from allied movements in their efforts to achieve critical mass. Organizations with hybrid identities—those whose organizational identities span the boundaries of two or more social movements, issues, or identities—are vital to mobilizing these constituencies. Studies of the post-9/11 U.S. antiwar movement show that individuals with past involvement in non-anti-war movements are more likely to join hybrid organizations than are individuals without involvement in non-anti-war movements. In addition, they show that organizations with hybrid identities occupy relatively more central positions in inter-organizational contact networks within the antiwar movement and thus recruit significantly more participants in demonstrations than do nonhybrid organizations.
The passage highlights that it's easier for hybrid organizations to attract people as compared to non-hybrid organizations. Option 2 does not even mention hybrid organizations and hence can be eliminated. Option 4 is only providing the example of 9/11 and hence cannot be the right choice for summary. Option 3 also makes use of attraction of people as an example, hence cannot be the right choice. Option 1 has to be the correct choice.
