从意思上说,似乎B更合乎逻辑.
但是毕竟不是母语,感觉不够明显,但是结合结构分析,似乎C又比较工整,郁闷了啊,哪个才是正确答案呢?

A and B is absolutely wrong.
base on the meaning, researcher agree 2 things. the second thing is more research is needed to accept the new technology.
C is balanced.
我的理解是原文中比较的是“balloon angioplasty preceded by ultrasound is any better for heart attack patients than the treatment itself is (better for heart attack patients)"
但是偶也是很迷惑到底这个is 要不要补出来, 要什么时候补出来呢?
究竟B or C? NN们来指点一下拉
