Which of the following is right ?
1. There is no agreement at present on what function,if any,certain herbs like X have in slowing the deterioration of or improving memory.
2. There is no agreement at present on what function,if any,certain herbs like X have in slowing the deterioration of or IN improving memory.
Which is right ? And why ? Splitting the sentence like
"certain herbs like X have IN slowing the deterioration of memory" and
"certain herbs like X have IN improving memory". So I picked up option 2. But is option 1. correct ?
