Hi Ceilidh/Dave,
How to deal with this long passage?
439) The primary purpose of the passage is to
A. compare the adaptive responses of several species of columnar cacti in the Sonoran Desert with those in the arid tropical regions of southern Mexico
B. discuss some of the possible causes of the relatively low abundance of migratory nectar-feeding bats in the Sonoran Desert
C. provide a possible explanation for a particular evolutionary change in certain species of columnar cacti in the Sonoran Desert
D. present recent findings that challenge a particular theory as to why several species of columnar cacti in the Sonoran Desert have expanded their range of pollinators
E. compare the effectiveness of nocturnal and diurnal pollination for several different species of columnar cacti in the Sonoran Desert
OA is C but are we discussing evolutionary changes? Isn't it about the pollinated. How does it happen in lack of availability?
Can you pls explain Q2 & Q3?
