manual weeding.

implementing its plan to develop the prototype?
A. There is a considerable degree of variation in shade of color between
weeds of different species.
B. The shade of color of some plants tends to change appreciably over the
course of their growing season.
C. When crops are weeded manually, overall size and leaf shape are taken into
account in distinguishing crop plants from weeds.
D. Selection and genetic manipulation allow plants of virtually any species
to be economically bred to have a distinctive shade of color without altering
their other characteristics.
E. Farm laborers who are responsible for the manual weeding of crops carry
out other agricultural duties at times in the growing season when extensive
weeding is not necessary.
