Original sentence: This increase in CO2 increases photosynthesis at varying rates, averaging 50%, contributing not only to higher yields but also to faster plant maturation, shrinking of pores, and greater resilience to water stress (both too much and little).
Quantified sentence: This increase in CO2 increases photosynthesis averaging at moderate rates, contributing not only to higher yields but also to faster plant maturation, shrinking of pores, and greater resilience to water stress (both too much and little).
Quantifier: moderate
