A team of botanists is investigating why a specific population of epiphytic orchids in a rainforest canopy has abruptly ceased flowering. The botanists establish their conclusion by systematically evaluating and refuting several competing hypotheses. Match each proposed hypothesis for the flowering failure with the specific empirical evidence that logically eliminates it.
- An influx of predatory beetles is consuming the developing buds before they can open.Botanists have documented a complete absence of physical damage or bite marks on the plants' upper extremities.
- The surrounding canopy has grown too dense, depriving the orchids of necessary sunlight.Solar irradiance meters installed beside the orchids demonstrate that they currently receive more ambient light than in previous decades.
- A specialized fungal pathogen is rotting the orchids' aerial root systems.Microscopic examination of the plants' aerial roots reveals entirely healthy, uninfected cellular structures.
- Recent climate shifts have eliminated the seasonal temperature drops necessary to trigger flowering.Continuous meteorological data confirms that nightly cooling patterns in the canopy remain completely unchanged from historical norms.
Cevap
Each hypothesis is eliminated by the specific premise that directly contradicts its proposed causal mechanism: insect predation is eliminated by a lack of physical damage, sunlight deprivation by contradictory irradiance data, fungal rot by healthy root tissue evidence, and climate shifts by historical temperature consistency.
The correct pairings successfully match each proposed hypothesis for the orchid's failure to flower with the specific empirical observation that structurally eliminates that hypothesis from consideration. This mirrors the LSAT method of argument by elimination, where mutually exclusive possibilities are systematically ruled out by direct counter-evidence.
