In E, being is not a modifier but a GERUND -- a verb functioning as a noun -- and is the subject of the verb is:
BEING heavily committed...IS likely to make an executive miss signs...
Thanks Mitch for your brilliant explaination on E, but i find it hard to differentiate modifier and gerund like this..."being heavily committed..." seems so much like a opening modifier. What should I consider when I come across a similar situation next time?
I have another question about the verb tense here. In E, there are both "in the past" and "has worked", but i wonder "in the past" is a sign for simple past tense?
My understanding to the confusion: present perfect means that the effect is still relevant(that is, "worked well" still remains true right now). In fact, the effect remains true for a long time, e.g for the past year, and that period is in the past, so these two tenses can be used together.
Hope I made myself clear!
LOOKING FORWARD TO YOUR ANSWER!
Thanks& Regards
