JbhB682 Wrote:(b) Replacing "THOSE" with possible antecedent
In 2010, X killed 200 pigs, fewer than pigs in 2006
The expression pigs in 2006 sets up a false comparison.
I need to compare
In 2010, X killed 200 pigs, fewer than Number killed in 2006
Thus eliminate iii)
Yes, this is the correct logic, but I think if you are going to use "number killed" to refer back to "pigs," you need a "which" and another verb in the 2nd part, so that both "pigs" and "number killed" are objects of their respective verbs:
In 2010, X killed 200 pigs,
which is fewer than
the number killed in 2006
You could also fix the comparison like this, depending on what you mean:
In 2010, X killed 200 pigs, fewer than
she/he/it did in 2006
In 2010, X killed 200 pigs, fewer than
Y did in 2006
