Explanation
Correct answer: D.
Choice D is the best answer. The text says that N.pudica’s prey-catching pitchers are underground. It also says that the ridges where N. pudica lives don’t have many plants and animals on the surface. This suggests that N. pudica evolved underground pitchers in order to catch more prey.
Why the other choices are wrong
Choice A
Choice A is incorrect. This inference isn’t supported. The text never mentions the possibility of other undiscovered carnivorous plant species in Indonesia, so there’s no basis to make this inference.
Choice B
Choice B is incorrect. This inference isn’t supported. The text does say that the ridges where N. pudica lives are dry, but it also says that the purpose of carnivorous plant pitchers is to capture prey. It never suggests that these pitchers also absorb moisture, so there’s no basis to make this inference.
Choice C
Choice C is incorrect. This inference isn’t supported. The text never suggests that N. pudica’s underground pitcher can catch animals on the surface, so there’s no basis to make this inference.
