If the increased sightings of birds species do not reflect an actual increase of species in the city, the advantage of the air pollution regulations will be greatly undermined since the evidence “the number of bird species seen in and around London has increased dramatically” is used to support the conclusion"Similar air-pollution rules should be imposed in other major cities"。So Choice E is an assumption.

Pay attention to the formulation of conclusion "Similar air-pollution rules should be imposed in other major cities". Nobody mentions "similar air pollution rules ON LOCAL INDUSTRY" , so whether it is the local industry that causes the main pollution does not matter.

In regard to question No.8, a dollar of benefits to farmer already costs consumers and taxpayers 4 dollars, the farm policy as a whole does cause tax payers billions and billions of dollars.
