so, here's the thing: once you have done something... well, that's true forever.
e.g., if you have seen a certain movie, or if you have smoked cigarettes, or if you have done just about anything... then you never STOP being "someone who has seen the movie", or "someone who has smoked cigarettes", etc.
these descriptions remain true in perpetuity. forever and ever and ever amen.
"known as" is incorrect unless it is followed by a noun:
Albert Einstein made his living as a patent clerk, but he was far better known as the original proponent of the theory of relativity.
--> correct (note that "proponent" is a NOUN)
The newly freed workers, seeking to become self-employed tenant farmers rather than wage laborers, made direct arrangements with merchants for supplies.
前提：作者假设：只有联系老人，才能有高成功率
This rate would be the expected rate if the only potential donors contacted were those who have donated in the past.
结论：只联系老人，不联系新人，不是好募捐者
——直接削弱假设：联系了新人，而不是仅联系老人
高成功率→（GAP）仅老人→不是好的募捐者
不用果因的结构想：这里真的好难说清楚前提和结论哦……
前提：老人成功率高（即新人成功率低），而好的募捐者应该扩大新人
since the people most likely to donate are those who have donated in the past, good fund-raisers constantly try less-likely prospects in an effort to expand the donor base
结论：成功率异常的高，反而说明了他们不努力（即联系的老人更多）
This success rate, exceptionally high for university fund-raisers, does not indicate that they were doing a good job.
The high success rate shows insufficient
注意：【exceptionally 异常的 格外的】
A 不对是因为和原文最后一句话“his may be at least in part because the greater the awareness customers retain about the cost of an item, the more likely they are to use it.“ 重复吗？
