第一，LZM说得没错。
第二，E逗号不能去，3个选项中我觉得只有3跟原来相近(单独作句子时），其它不可取。

1, 答案，D，从时态可以选出来，但是如果把E，was改成 has been意思上有什么细微差别？economics for four decades has been one that --->> i don't think so. as here 'for 4 decades' modifies science, changed meaning.
2, E,the board of directors ,at its quarterly meeting ,raised the possibility of adding worker incentives
key is E,E中去掉逗号，对意思有影响吗？ --> the reason is the same to 1
3, 1.the board of directors raised at its quarterly meeting the possibility of adding worker incentives
2.the board of directors raised the possibility of adding worker incentives at its quarterly meeting
3.at its quarterly meeting，the board of directors raised the possibility of adding worker incentives
三句话除了强调的重点不同外，意思一样吗？ ---> yes to 1 and 2; 3 is no good
