请教:第一次做这题很快就选出E,现在又不懂了......
OG11-111里面解释说
if that product has been successful so far, then expanded production and continued advertising should lead to continued success.推出any evidence that the company's product has been failing would undermine the anticipated success of a plan to increase sales.
A 推出B,怎么可以得到NOT A 推出NOT B呢?这不只是否命题吗? |
