# determine chrysanthemum color given an input soil pH level
#       acidic soil produces pink chrysanthemums
#   non-acidic soil produces blue chrysanthemums

# acidity threshold

ACIDIC_THRESHOLD = 7.0     # samples less than threshold are acidic

# get soil pH level of interst

# analyze and report effect on chrysanthemums
#   if acidic print 'pink';  otherwise print 'blue'
