Which one of the following is an assumption the environmentalist's argument requires?
In at least some landfills that have been converted into public parks there are bacteria that degrade household cleaning products.
Converting a landfill into a public park will cause no damage to human health unless toxic vapors are produced in that landfill and humans are exposed to them.
If a practice involves the exposure of humans to vapors from household cleaning products, then it causes at least some damage to human health.
When landfills are converted to public parks, measures could be taken that would prevent people using the parks from being exposed to toxic vapors.
If vapors toxic to humans are produced by the degradation of household cleaning products by bacteria in any landfill, then the health of at least some humans will suffer.
