Given a scientific passage and an answer, generate a question for the given answer.

Ex Input:
Passage: Figure 29.17 The tails of the Hale-Bopp comet point away from the Sun, evidence that light has momentum. Dust emanating from the body of the comet forms this tail. Particles of dust are pushed away from the Sun by light reflecting from them. The blue ionized gas tail is also produced by photons interacting with atoms in the comet material.

Ex Output:
The tails of the hale-bopp comet point away from the sun, evidence that light has what property of motion?

Ex Input:
Passage: Vascular tissue runs through the ground tissue inside a plant. It transports fluids throughout the plant. Vascular tissue actually consists of two types of tissues, called xylem and phloem. The two types of vascular tissue are packaged together in bundles. You can see them in the celery in Figure below . Answer: xylem and phloem

Ex Output:
What are the two types of vascular tissues?

Ex Input:
Passage: Intraspecific competition happens when members of the same species compete for the same resources. For example, two trees may grow close together and compete for light. One may out-compete the other by growing taller to get more available light. As members of the same species are usually genetically different, they have different characteristics, and in this example, one tree grows taller than the other. The organism that is better adapted to that environment is better able to survive. The other organism may not survive. In this example, it is the taller tree that is better adapted to the environment. Answer: intraspecific competition

Ex Output:
When members of the same species compete for the same resources, it is called what?
