Input: Read this: Nociceptive pain is caused by stimulation of peripheral nerve fibers that respond to stimuli approaching or exceeding harmful intensity (nociceptors), and may be classified according to the mode of noxious stimulation. The most common categories are "thermal" (e.g. heat or cold), "mechanical" (e.g. crushing, tearing, shearing, etc.) and "chemical" (e.g. iodine in a cut or chemicals released during inflammation). Some nociceptors respond to more than one of these modalities and are consequently designated polymodal.
Question: What type of pain is caused by stimulation of fiber?

Output: unanswerable


Input: Read this: The Royal College of Chemistry was established by private subscription in 1845 as there was a growing awareness that practical aspects of the experimental sciences were not well taught and that in the United Kingdom the teaching of chemistry in particular had fallen behind that in Germany. As a result of a movement earlier in the decade, many politicians donated funds to establish the college, including Benjamin Disraeli, William Gladstone and Robert Peel. It was also supported by Prince Albert, who persuaded August Wilhelm von Hofmann to be the first professor.

Input: Read this: The term "push-pull" was established in 1987 as an approach for integrated pest management (IPM). This strategy uses a mixture of behavior-modifying stimuli to manipulate the distribution and abundance of insects. "Push" means the insects are repelled or deterred away from whatever resource that is being protected. "Pull" means that certain stimuli (semiochemical stimuli, pheromones, food additives, visual stimuli, genetically altered plants, etc.) are used to attract pests to trap crops where they will be killed. There are numerous different components involved in order to implement a Push-Pull Strategy in IPM.
Question: What is one thing that can be used to pull pests?

Output:
food additives
