在gmatclub看到关于选项E是strengthener的解释,不是特别理解。有没有小伙伴能给解释一下呢?
如下:
Let's put it in simple terms:
Say I tell you:
People believe that solving Math maintains mental sharpness. But actually social interaction is enough. A study showed that people with more social activity have better mental skills.
Now, A says, " Mental skills were measured by checking language skills."
and B says, "Mental skills were measured by checking Math skills."
- who is strengthening my argument and who is weakening it?
A is weakening my argument since if mental skills were measured by language skills, obviously people with more social activity will report higher skills. It doesn't need to imply that social interactions lead to sharper mental skills. If all you are going to check is how well people can interact, the study will show that social people will have higher mental skills.
B strengthens my argument that social activity actually increases even the quantitative ability - which is probably one of the measures of mental skills. Hence, it does make my argument stronger that social activity is enough to improve mental skills - no matter how you measure mental skills.
Option (E) says what B says in my example. Hence it is not a weakener; it is, perhaps, a wee bit of a strengthener.
