12) B
The argument made in the text is the last line “The government should act now…make slimming pills object to the same strict controls as medicines”
Our answer must be a statement which weakens this argument.
A – Wrong
People wasting their money on many products besides slimming pills does not weaken the argument that the government should take action.
B – Correct
If the government is introducing a legislation then it weakens the argument that the government should take action.
C – Wrong
Even if the statement that the demand for slimming pills is likely to grow was true, it does not weaken the argument that the government should take action.
D – Wrong
Even if this was a cost to the taxpayer, the government would be saving people’s money from being wasted on ineffective slimming pills.
E – Wrong
This statement cannot be correlated with the argument made.
