PT94.S4.Q15 - Scholars writing histories of an era's business practices

Doesn't [D] just strengthen the premise that scholars are more likely to study successful businesses than unsuccessful businesses? Can someone explain to me why it's right? It doesn't seem to strengthen the support that being more likely to study successful businesses -> overestimating successes of past businesses.

I chose [E] because it seemed to directly relate to the support. Just because scholar are more likely to study successful businesses doesn't mean that they're overestimating the successes of past businesses... what if they're also including setbacks that those successful businesses had along the way? [E] seems to guard against this potential weakness by saying that historical records actually don't allow historians to infer those setbacks. Why is [E] wrong?!
