Question 27
Original source text (the original panel preserves all diagram labels, tables and choices):
On February 2005, a tragedy occurred in a village in West Java, Indonesia. In the
early hours of the morning, an explosion followed by an avalanche of garbage
occurred in the Leuwigajah landfill site. The explosion at the landfill is thought to
have originated from an accumulation of methane gas in the mountains of garbage.
Prior to the explosion, rain had been falling in the area for several days.

Which statement is an INCORRECT assumption regarding the incident above?
A. Methane gas piles formed due to the decomposition of organic matter by
methanogenic bacteria.
B. Methane gas explosion occurs because decomposition by bacteria absorbs heat
so that fire can form.
C. One way to prevent methane gas explosions is to ventilate areas suspected of
containing methane gas.
D. Continuous rain causes a humid environment, making it easier for bacteria to
multiply and decompose organic matter.
