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 products 
which 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 wav to deal with them is through controls over their supply, 
use and disposal 
13. In accordance with the passage, the threat of some certain substances to the environment............. . 
A) is for less than that to man 
B) could be reduced by enforcing emission limits and environmental controls 
C) has been unnecessarily over emphasized 
D) has to date been completely ignored 
E) can be eliminated by the use of industrial waste streams 
14. The author expresses that the danger posed to man by some substances ............. . 
A) is even greater than generally admitted 
B) is unrelated to environmental pollution 
C) continues to grow despite constant control of disposal systems 
D) is solely due to the use of industrial waste streams 
E) arises from their misuse and wrong disposal 
15. 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 
The Peter Principle is derived from the analysis of the hundreds of cases of incompetence in organizations 
which can be seen anywhere. The principle points out that in a hierarchy every employee tends to reach his 
level of incompetence and it applies to all organizations. The Principle assumes a constant quest for high 
performance. Hence people competent at their jobs are promoted so that they may do still better. 
Competence in each new position 
qualifies for promotion to the next until each individual reaches a job beyond his abilities and therefore no 
longer performs in a way that gains further promotion. This is his level of incompetence Given two 
conditions enough ranks in the hierarchy to provide promotions and enough time to move through them all 
employees reach and remain at their level of incompetence. This can be stated as Peter's Principle: In time, 
every post tends to be occupied by an employee who is incompetent to carry out its duties.
16. The level of incompetence ..............
A) is the level that the Principle assumes a constant quest foil high performance.
B) is somehow a degree of a post where one cannot perform well enough to receive any further promotion.
