Answer:
The Arab Spring and the OWS movements were the first to use Internet effectively to recruit and mobilize protests.
Explanation:
The Internet, and especially social networks, played a significant role in these events. Some of the commentators even argued that without social networks, an Arab Spring would not have taken place. It was sometimes said that revolutions were supposedly just a consequence of the spread of new information and communication technologies, such as social networks and microblogging. In recent years, new means of communication using the capabilities of the Internet have begun to fulfill the functions of classical media, especially in the political field.
The political crisis in the Arab states has turned the minds of not only the civilian population of these countries, but also the world community. Given the possibility of cross-border coverage of the audience, social media were used not only for free virtual communication, but also became a mechanism for organizing coups.
Participants in the spontaneous OWS movement found supporters and coordinated their actions on social media. Moreover, it was emphasized that this movement did not have any formal leader.
Answer: Echoic memory
Explanation: Since Jamal's brother was not listening to what he was saying and can still easily recap some of what he said for the last few seconds he is using his echoic memory to recollect those information.
Echoic memory is a type of sensory memory used by the auditory system. Echoic memory can store a large amount of auditory information, but only for few seconds (3 - 4 seconds). This echoic sound is replayed in the brain for this short period of time immediately after the presentation of the auditory stimulus.
The Industrial Revolution transformed economies that had been based on agriculture and handicrafts into economies based on large-scale industry, mechanized manufacturing, and the factory system. New machines, new power sources, and new ways of organizing work made existing industries more productive and efficient.
<u>Key features of the Industrial Revolution</u>
- Population shift – moving from rural agriculture to work in factories in cities.
- Mass production of goods, increased efficiency, reduced average costs and enabled more to be produced.
- The rise of steam power, e.g. steam trains, railways and steam-powered machines.
