29. 题目只给出了TORONTO-DALLAS 的全价票价格不变, 并没有说该航空公司其他线路所有的全价票价格不变,所以C不对.

51. B 是明显的桥梁型加强.
例如, 科学天才 ------    好处, 之间架一个桥梁便是Politically powerful people  reward them.

C是无关选项,正确与否不能影响结论.

technical ingenuity usually brings benefits to those who have this ingenuity, 是指拥有科学天份的人，这种天份会带给他们（指他们自己，非有政治权力的人）好处，这里存在一个ASSUMPTION：Politically powerful people tend to reward those who they believe are useful to them ；

同理，ethical inventiveness 也会给拥有它们的人带来痛苦，ASSUMPTION：Politically powerful people tend to punish those who they believe are a threat.

ASSUMPTION 是 STRENGTHEN 的子集，自然是对结论的加强。
