A company's personnel director surveyed employees about their satisfac

PREMISE
--A company's personnel director surveyed employees about their satisfaction with the company's system for awarding employee performance ratings.
--The survey data indicated that employees who received high ratings were very satisfied with the system.

CONCLUSION
--the company's best-performing employees liked the system.

There is a gap in the argument--survey data indicated that employees who received high ratings were very satisfied with the system
from this author concluded that the company's best-performing employees liked the system.
--by saying this author assumes that --the company's best-performing employees and employees who received high ratings are same (this bridges the link between premise and conclusion--this is supporter assumption)

A. No other performance rating system is as good as the current system.
--we are not concerned about other performance rating system
--this answer choice does not help our conclusion in any way--this need not to be true for our conclusion to hold
(irrelevant)

B. The company's best-performing employees received high ratings.
---this is the correct answer choice this matches our prethinking
---negating this--The company's best-performing employees do not received high ratings then we cant say that they are satisfied with the system and our conclusion falls apart--(correct)

C. Employees who received low ratings were dissatisfied with the system.
--negate this --Employees who received low ratings were satisfied with the system
---this does not say anything about our conclusion--we don't know anything about high performing employees
--our conclusion can still hold (incorrect)

D. Employees who receive high ratings from a performance-rating system will like that system.

--this answer choice does not bridge the gap between Employees who receive high ratings and high performing employees
--negating this--Employees who receive high ratings from a performance-rating system will not like that system.
---but still, we can't say anything about high performing employees---there is a possibility that high performing employees do not receive high rating but still like the system--so, our conclusion still holds (incorrect)

E. The company's best-performing employees were motivated to perform well by the knowledge that they would receive performance ratings.

---this answer choice does not reinforce our conclusion
---negating this does not shatter our conclusion
---there is a possibility that the high performing employees like the system ---our conclusion can still hold
--this cant be the assumption (incorrect)
