Question of the Day 
Answer the question based on the passage given below.

David Colquhoun, a pharmacologist at University College London and a member of the Complementary and Natural Healthcare Council, wants the National Institute for Health and Clinical Excellence, which rules on the cost-effectiveness of traditional therapies, to examine the evidence for complementary medicine. “The whole problem of regulating alternative medicine will remain impossibly chaotic until the government grasps the nettle of deciding what works and what doesn’t,” he says.

Which of the following best strengthens the argument of the pharmacologist David Colquhoun?
 1)Consumer protection laws that forbid false claims that a product can cure a disease need to be strengthened.
 2)Alternative medicines do not work or have never been tested.
 3)Agencies specially constituted to license conventional drugs, excuse homeopathy, unlike other treatments, from proving it is more effective than a placebo.
 4)In traditional therapies, there are bodies that oversee doctors and nurses and ascertain whether their practitioners’ efforts actually work.
 5)The Advertising Standards Authority can decide on whether alternative medicine does what it claims to.
