Rex did poorly on his biology exam and blames his teacher. He does not feel like she prepared him for the exam, even though he went out the night before the exam to a party, and didn't finish reading the chapters. After taking the test, he complained to his classmate that the test was unfair. Rex believes that chance, luck, and the behavior of others control his life. According to Rotter, Rex has a(n) locus of control.

External locus of control

Explanation:

In simple words, People who have an external center of authority feel that events in their life are beyond their management, meaning that sometimes their own acts are the consequence of other causes such as destiny, misfortune, the persuasion of strong outsiders (such as physicians, cops, or government leaders), and/or faith.

Thus, from the above we can conclude that the correct answer is external locus of control.

new communications technology has affected the way social movements are organized because nowadays, social movements rely on social networks and the media to get different people with a similar way of thinking in contact, and thus, get them to mobilize for a greater cause.

individuals only participate in collective action when they feel identified with it. is in this aspect that social media becomes relevant, because it guarantees communication among all individuals and organizes the social actions that are going to be carried out, i.e., the social movements.

in addition, being covered by the media is important to validate the message and make it relevant in the social agenda, as well as to reach more people who can share interests, appealing to public sympathy for their cause.

in conclusion, it is by social networks and social media that social movement is given birth; by connecting different individuals with similar ideas and organizing them to mobilize for a greater cause.
