Dried grass clippings mixed into garden soil gradually decompose, providing
nutrients for beneficial soil bacteria. This results in better-than-average plant
growth. Yet mixing fresh grass clippings into garden soil usually causes poorer-
than-average plant growth.
Which one of the following, if true, most helps to explain the difference in plant
growth described above?
(A) The number of beneficial soil bacteria increases whenever any kind of plant
material is mixed into garden soil.
(B) Nutrients released by dried grass clippings are immediately available to
beneficial soil bacteria.
(C) Some dried grass clippings retain nutrients originally derived from commercial
lawn fertilizers, and thus provide additional enrichment to the soil.
(D) Fresh grass clippings mixed into soil decompose rapidly, generating high levels
of heat that kill beneficial soil bacteria.
(E) When a mix of fresh and dried grass clippings is mixed into garden soil, plant
growth often decreases.
