Critical Reasoning

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.

OA in a day or two

Dried grass provides nutrients for soil bacteria and soil bacteria is resp for better growth
Fresh grass causes poor than avg growth.

Opinion: Bring in the relation btw fresh grass and bacteria.. An oppisite relation is good

D) matches my opinion: Fresh grass kills bacteria..

IMO D in 1.34seconds

It has to be between B and D.

D talks about the poorer than average growth reason.

IMO D.

@HSPA -- superfast .

@Rahul -- Is this from 1000CR or LSAT ?

IMO D: 75 secs approx

The question asks us to explain the difference in plant growth described above?

Why dried glass clippings are effective already explained well in the argument...means we should look for the reasoning for fresh glass clippings. Op D correctly refers why there is a difference.

Op B and D further explaining the role of dried glass clippings rather than differentiating

OA is D
@AIM this is an LSAT question buddy

congrats guys for getting right.....my personal timing in this one was 55secs....was slightly confused though inbetn B and D

guys have a query about 1000CR

've done almost all questions but found many ans debatable...even the ones OG included in the doc din't have right ans.........is this source useful?

have read mixed reviews abt 1000 source. if u do want to do it you may find it helpful to google answers u find dubious. no point fretting over a wrong OA, it would hurt your confidence more.

+1 for D. That is the most appropriate explaination.
