On the planet Vextrion-9, researchers have observed that atmospheric distortions occur precisely 24 hours before the emergence of massive energy surges from the planet’s core. Scientists from the Galactic Observatory concluded that these distortions must be a form of predictive signaling emitted by the planet itself, indicating an unknown form of planetary intelligence.
Which of the following, if true, most seriously weakens the scientists’ conclusion?
(A) The atmospheric distortions have only been observed in certain regions of the planet, while energy surges occur globally.
(B) The energy surges from the planet’s core have been increasing in magnitude over the past century, while atmospheric distortions have remained constant.
(C) A recently discovered subterranean species on Vextrion-9 has been found to release a unique type of electromagnetic pulse that could be responsible for the observed distortions.
(D) Similar atmospheric distortions have been detected on lifeless planets with no recorded energy surges.
(E) The energy surges from the planet’s core contain complex patterns that resemble known forms of coded communication.

C for me.
LOR involves creating of causation relationship between two things (Distortions preceding energy surges). Such, arguments can be weakened generally by either showing correlation & not causation, reverse causation, third factor responsible for the effect rather than said one. Weaken question attacks line of reasoning & not the premise.
A. So what? Adds more info to premise rather than do anything to arguement
B. Okay great but it doesnt still attacks argument's causation
C. Intersting & keep. Another reason to explain the distortions rather than "planetary intelligence"
D. Trap choice?
E. Strengthens instead

I created this question myself based on science fiction themes and common logical reasoning structures used in GMAT and LSAT Critical Reasoning (CR) questions. It is not from any official source but is designed to be a challenging weakening question in the science fiction domain.
