(A) baggage so light
(B) baggage being so light
(C) baggage, yet being so light
(D) baggage, and so light
(E) baggage yet was so light
Choice E, the best answer, states that although the canoe could transport cargo of considerable weight, it was light: a canoe... which could carry... yet was... light.... Here, the conjunction yet is appropriately and correctly used to link two verb phrases. Choices A and B do not use yet with a verb parallel to could carry and thus fail to express this contrast. Furthermore, both place adjectival constructions after baggage, illogically stating that the eight hundred pounds of baggage, rather than the canoe, was light. Choice C supplies yet but ungrammatically uses the participle being where was is required. Similarly, D omits the necessary verb after and; and here again, the use of and rather than yet fails to express the contrast.
這題沒問過，想請教的是:
我可以認同這一題必須提及yet，沒有yet沒有轉折，標準答案給的是(E) baggage yet was so light
但如果改成baggage yet so light (在yet之後沒有動詞)
或是baggage, yet so light(baggage後面有,同時yet之後沒動詞)
換句話說，逗號與be動詞在這扮演什麼角色
