What is Sabrina Corlette's attitude towards the new insurance plans? ( )

参考解析：

从原文尾段可以得知：If these alternative plans prompt doctors and hospitals to lower prices, "then that is worth taking a closer look," says Sabrina Corlette, a research professor at Georgetown University's Health Policy Institute. "But if it's simply another flavor of shifting more risk to employees. I don't think in the long term, that's going to bend the cost curve."如果这些替代计划促使医生和医院降低价格，“那么这值得仔细研究。”但如果这只是将更多风险转移给员工的另一种方式。我认为，从长远来看，这不会改变成本曲线。”可以看出专家先是if假设的肯定，后面又有but转折的假设，因此对此更侧重于持消极态度。故本题正确答案选C。
