Chemical-company employee: A conservation group's study of the pollutants released into the environment by 30 small chemical companies reveals that our company and four other companies together account for 60 percent of the total. Clearly, our company releases more pollutants than most chemical companies similar to us in size.
Which one of the following is an assumption required by tbe employee's argument?
(A) The conservation group that produced the study is not hostile to the chemical industry.
(B) The employee's company does not produce chemicals whose processing naturally produces more pollutants than the chemicals produced by other small chemical companies.
(C) The total pollution produced by all small chemical companies combined is not greatly outweighed by that produced by large chemical companies.
(D) The four other companies mentioned by the employee do not together account for very close to 60 percent of the total pollution by the 30 companies.
(E) There is no significant variation in the quantities of pollutants released by the other 25 small chemical companies.

(A) The conservation group that produced the study is not hostile to the chemical industry.
This choice is irrelevant
(B) The employee's company does not produce chemicals whose processing naturally produces more pollutants than the chemicals produced by other small chemical companies.
This choice could be tricky. We care about the pollutant only. Those chemicals that produce more pollutants are irrelevant.
(C) The total pollution produced by all small chemical companies combined is not greatly outweighed by that produced by large chemical companies.
We don't care about large chemical companies. We care about small chemical companies only.
(D) The four other companies mentioned by the employee do not together account for very close to 60 percent of the total pollution by the 30 companies.
This wordy choice is actually correct. It just tries to say that four other companies don't account for 60% of the total pollution. If those companies account for nearly 60%, the employee's company will account for nearly 0%. Thus, the argument is weakened.
(E) There is no significant variation in the quantities of pollutants released by the other 25 small chemical companies.
We care about the employee's company only. Don't care about 25 other companies.

Chemical-company employee: A conservation group's study of the pollutants released into the environment by 30 small chemical companies reveals that our company and four other companies together account for 60 percent of the total. Clearly, our company releases more pollutants than most chemical companies similar to us in size.
Notes
study: 30 chem. co.
us + 4 co. = 60% total pollutants
us release > pollutants than most chem. co.
Analysis
This poorly informed employee has miscalculated…maybe! He argues that his company and 4 others account for 60% of the total pollutants and then goes on to say his company must produce more pollution than most (>50%) of the 29 other companies. He clearly must assume we produce more than 50% of the total pollution?!
Which one of the following is an assumption required by tbe employee's argument?
(A) The conservation group that produced the study is not hostile to the chemical industry.
Their hostility is not relevant to the employees judgement regarding % of pollutant released.
(B) The employee's company does not produce chemicals whose processing naturally produces more pollutants than the chemicals produced by other small chemical companies.
Not relevant.
(C) The total pollution produced by all small chemical companies combined is not greatly outweighed by that produced by large chemical companies.
We only care about small company issues - not the large ones.
(D) The four other companies mentioned by the employee do not together account for very close to 60 percent of the total pollution by the 30 companies.
Aha! Our pre-think is found!
(E) There is no significant variation in the quantities of pollutants released by the other 25 small chemical companies.
OK, but to conclude that his company produces more pollution than MOST….the other 25 companies only account for 40%….and without knowing anything about the breakdown of the 60%, he can’t conclude anything!
