Text A, Paragraph 2
In recent years, the UK has faced criticism for the lack of funding towards its public libraries, which provide free educational resources and community spaces accessible to all.

Critics argue that without government funding, many communities will lose access to these important resources.

Text D, Paragraph 4
In recent years, Kenya has introduced several community health programmes, including free vaccination clinics and health education workshops.

Private healthcare providers argue that they have little incentive to offer these services. Government officials are debating whether to increase funding for these public health initiatives, given their significant benefits for public safety and the overall economy.

Explain why community health programmes might be under-provided by private firms in a free market.

Text C, Paragraph 3
The USA’s coastal areas rely on flood defences to protect communities from extreme weather events. Recently, scientists have warned of rising sea levels and urged the government to increase funding for flood barriers and other defences. Since flood defences protect all residents equally and are accessible to everyone, they are considered public goods. Private companies are unwilling to build or maintain them so as a result, flood defence projects remain underfunded despite their importance for public safety.

Explain why flood defences might be under-provided by private firms in a free market.
