I'm really confused by the choice B, because i think the verb "extended" is parallel to "was"
"...was the Incan highway and extended..."
In this case, "extended" is used as a past tense. actually it is a helping verb, paralleled with "was".
Also, since the"extended" works as a verb, it means the same as "extending" ( i mean the meaning, not the function.)
correct me, please.
thanks a lot.
