Which city and year witnessed terrorist attacks that led to a pledge by the national government to eliminate violent extremist content online?

• A. Christchurch, New Zealand, 2019
• B. Paris, France, 2015
• C. Mumbai, India, 2008
• D. Berlin, Germany, 2016

Answer: (A)

High-profile terrorist incidents often prompt governments to commit to stronger actions against online extremism. The Christchurch attack in 2019 in New Zealand is the event where the national government publicly pledged to eliminate violent extremist content online, pushing platforms to remove such material quickly and to take broader measures to curb online extremism. This explicit pledge tied to that specific incident stands out, whereas the other listed attacks did not yield the same widely publicized commitment to eradicating violent extremist content on the internet. So, Christchurch in 2019 is the correct association.
