请教两道语法题~0410

24. The color and pageantry, keen rivalry, and high level of competition both contribute to the great worldwide interest in the Olympic Games.

答案： Ｃ both>> all

为什么B选项level前面没有限定词阿？？？

38. Animals have to cope with and control physical and chemical processes that do not necessarily act to benefit of the animal.

答案： D to benefit>> to the benefit of

分析：不要to ,因为act在这里做vi. 而benefit本身可作n.。所以to多余。我觉得这个应该是改成 the benefit of， 是the N of the N 的结构。Act作不及物动词，表示to perform a specified function

这是CD语法笔记里的~~  vi.为什么没有to~~confused~~~到底有没有to~~~
