15. Most substances, either artificial or natural, can
cause harm to man or the environment. Some of
these reach the environment in waste streams;
however, emission limits and environmental quality
standards can, in some instances, reduce the
amounts released. However, some other matters
cannot be controlled in this way because they are
released, not in industrial waste streams, but through
the use or disposal of products that contain them. In
many cases, these substances pose little or no threat
if the product containing them is used and disposed
of properly. The accurate way to deal with them is
through controls over their supply, use and disposal
The passage is related to the question of
.............. 
A) how the harmful effects of certain substances can
be kept under control 
B) why industrial waste streams have led to so much
pollution 
C) what measures are to be taken against the supply
of dangerous substances 
D) if man-made substances and natural ones cause
pollution 
E) who is responsible for taking the required
precautions
