Parsley Garden

by Brian Shimanuki

Answer:
LITHIUM

We have a grid of 49 words. The title and the flavor hint that we should form and parse sentences as garden path sentences. It turns out that these garden path sentences have unique lengths from 4 to 10.

LengthSentence (parsing)
4(the poker) faces ire
5(words endorsing her) answer skeptics
6before splitting, cells double their content
7(the boy [that] trolls (n.) mother (v.)) boards the sled
8(steps reducing energy drain) incorporate hydration and rest
9when children who have tempers eat, food gets thrown
10descending into troubles [that] the president induced, she dissolves the company

Reading out the starting words yields THE WORDS BEFORE THE STEPS WHEN DESCENDING. In the grid, each sentence has a single step that goes downward, except the length 7 sentence has two consecutively. Reading the top word in each descent step in sentence length order yields THE ANSWER CELLS (MOTHER BOARDS) DRAIN HAVE DISSOLVES.

If we take MOTHER BOARDS to mean MOTHERBOARDS, this can be read as a similar type of parsing sentence called a center embedding.

(THE ANSWER [that] (CELLS [that] MOTHERBOARDS DRAIN) HAVE) DISSOLVES

The meaning of this is that motherboards drain cells that have the answer, which dissolves.

This refers to CMOS batteries, which are generally a CR2032 lithium primary battery. The answer is the solid inside the battery which dissolves during the chemical reaction (oxidation), which is LITHIUM.
