Question

the passage below describes an experiment. britney liked to make guacamole, but she often found only unripe avocados at the grocery store. britney learned that ripe fruits produce a gas called ethylene, which can cause other fruits to ripen. she thought that storing ripe bananas with avocados would make the avocados ripen faster. britney placed three unripe avocados in each of six bags. she added one ripe banana to two of the bags and three ripe bananas to two other bags. she did not add any bananas to the remaining two bags. then britney sealed all six bags. after two days, she counted the number of ripe avocados in each bag. in this experiment, which were part of an experimental group? the bags with three avocados and one banana the bags with three avocados only

Answer:

the bags with three avocados and one banana
