Difficulty: MediumInferential Comprehension and Deduction

Read the passage below carefully and evaluate the statement that follows:

In the lush bamboo thickets of Benishangul-Gumuz, Ethiopia, indigenous communities have traditionally utilized highland bamboo for temporary fencing and domestic fuelwood. However, rapid deforestation across neighboring hardwood reserves has recently reshaped local resource management. Recognizing the plant’s rapid regeneration cycle and high tensile strength, regional forestry cooperatives established decentralized solar-kiln processing centers. These facilities dry raw culms under controlled thermal conditions, significantly mitigating the internal moisture retention that historically rendered raw Ethiopian bamboo vulnerable to fungal decay and beetle infestation within months of harvest. Additionally, by structural density treatment, processed bamboo culms now match the load-bearing capacity of seasoned eucalyptus timber, allowing local builders to construct durable multi-story modular housing. Crucially, the transformation process also captures bamboo offcuts, converting them via low-oxygen pyrolytic kilns into dense bio-char charcoal briquettes. This dual innovation has not only reduced rural reliance on old-growth forest timber by over forty percent in surrounding districts, but it has also established a sustainable carbon-neutral fuel source that commands a premium in urban energy markets.

Statement: Prior to the establishment of solar-kiln processing facilities, the vulnerability of untreated Ethiopian bamboo to biological decay was directly driven by its retained internal moisture.

Answer: Answer

Answer

The statement is True. The passage explicitly links the historical vulnerability of raw bamboo to fungal decay and beetle infestation directly to its internal moisture retention, which thermal solar-kiln drying was designed to solve.
The statement is logically sound because the text demonstrates that solar-kiln centers eliminate moisture retention, which previously exposed raw culms to rapid fungal and insect attack. Deductively, retained internal moisture was the key physical vulnerability of untreated bamboo.

Step-by-Step Solution

1
Identify the passage section describing untreated bamboo's structural limitations.
The text notes that raw culms suffered from fungal decay and beetle infestation within months of harvest due to internal moisture retention.
To determine the cause of historical degradation in raw bamboo.
2
Connect the terms in the statement to the passage details.
'Biological decay' encompasses fungal decay and beetle infestation, while 'internal moisture' is identified as the factor causing this condition.
To synthesize textual evidence and evaluate the statement's logical validity.
3
Formulate the final deduction.
Because drying mitigates moisture to prevent fungal/insect damage, retained moisture was the primary driver of biological decay prior to processing.
To verify the statement as True.
