Passage: The root schism was between the Sthaviras and the Mahāsāṅghikas. The fortunate survival of accounts from both sides of the dispute reveals disparate traditions. The Sthavira group offers two quite distinct reasons for the schism. The Dipavamsa of the Theravāda says that the losing party in the Second Council dispute broke away in protest and formed the Mahasanghika. This contradicts the Mahasanghikas' own vinaya, which shows them as on the same, winning side. The Mahāsāṅghikas argued that the Sthaviras were trying to expand the vinaya and may also have challenged what they perceived were excessive claims or inhumanly high criteria for arhatship. Both parties, therefore, appealed to tradition. Question: The Mahasanghikas argued that the Sthaviras were trying to expand what?

Ex Output:
the vinaya

Passage: They can also be armed with non-lethal (more accurately known as "less than lethal" or "less-lethal") weaponry, particularly for riot control. Non-lethal weapons include batons, tear gas, riot control agents, rubber bullets, riot shields, water cannons and electroshock weapons. Police officers often carry handcuffs to restrain suspects. The use of firearms or deadly force is typically a last resort only to be used when necessary to save human life, although some jurisdictions (such as Brazil) allow its use against fleeing felons and escaped convicts.

With the country having one of the highest rates of violent crime, president Jacob Zuma states that South Africa needs to handle crime differently from other countries.

allows police to use deadly force against any person who poses a significant threat to them or civilians
