What are the main concerns about the social media app mentioned in the text, and why does Mossi want to halt its activities?

a) The excerpt is placed in the following immediate context:

Before: The discussion among Mossi, Pirro, Narine, Nicole, and possibly Alvit revolved around the social media app. Mossi expressed an urgent need to stop the app, questioning Narine about its true nature, while Pirro doubted their authority to intervene.

After: The conversation would likely continue with a response from Pirro or Nicole regarding Mossi's suggestion to involve the Ministry of Education, or further deliberation on strategies to effectively halt the app's activities.

b) According to the excerpt, the ills of social media are:

• Its true nature or purpose has not been adequately explained.
• It contains "fundamental errors" that require immediate attention.
• It is deemed problematic enough to warrant being stopped.

c) From the knowledge of the text provided in the excerpt, Mossi wants to halt the activities of the App because he believes it contains "fundamental errors" that need to be addressed. He is convinced that the app, which is a school project, is problematic and insists that it must be stopped immediately. He also implies that the app's true nature was never properly explained, contributing to his strong desire to cease its operations.
