Q2: Evaluate these statements concerning government intervention, using economic reasoning

a) "Scientific discovery is essential for furthering the welfare of humanity. However, it is essentially a public good. Consequently, the private sector would fail to allocate sufficient resources toward scientific discovery, and we need the public sector to be heavily involved. "

However, these problem would be addressed much more efficiently by educating people so they better understand the consequences of these behaviours for their health and well-being."
