想請教一下各位大大們:

B選分詞邏輯主語是否變成Brazil releae African honeyees,所以改變句意

至於C選解答我看不懂????,各位大大們請幫忙解釋please……….

17. The new image of Stone Age people as systematic hunters of large animals, rather than merely scavenging for meat, have emerged from the examination of tools found in Germany, including there wooden spears that archaeologists believe to be about 400,000 years old.

A. merely scavenging for meat, have emerged from the examination of tools found in Germany, including

C. as mere meat scavengers, has emerged from examining tools found in Germany that includes
    

D. mere scavengers of meat, has emerged from the examination of tools found in Germany, which includes

E. mere scavengers of meat, has emerged from the examination of tools found in Germany, including

C選解答表示: that includes修飾前面的Germany，修飾對象不對，應該改成include?????

為何改成include,因為include不是動詞,這結果不就變成2V……….還是我的理解有誤????

18. There is a widespread belief in the US and Western Europe that young people
have
     a smaller commitment to work and a career than their parents and
grandparents
    and that the source of the change lies in the collapse of the
'work ethic'.
    

A. a smaller commitment to work and a career than their parents and grandparents
    

B. less of a commitment to work and a career than their parents and grandparents
    

C. a smaller commitment to work and a career than their parents and grandparents
    

D. less of a commitment to work and a career than their parents and grandparents
had
    

E. a lessening of the commitment to work and a career than their parents and
grandparents had

下面解釋的部份是我不解的地方,這題我看到A和C選的a smaller commitment 就不會想選因為我覺得本題commitment用smaller修飾很奇怪但看到解答說 : less of 的less是名詞，和a smaller commitment都對???看不太懂???

以上希望各位大大能幫忙解惑………….
