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

Input: Consider Input: Passage: Watch this video (http://openstaxcollege. org/l/vertebrate_evol) of biologist Mark Kirschner discussing the "flipping" phenomenon of vertebrate evolution. The nervous system is made up of neurons, specialized cells that can receive and transmit chemical or electrical signals, and glia, cells that provide support functions for the neurons by playing an information processing role that is complementary to neurons. A neuron can be compared to an electrical wireit transmits a signal from one place to another. Glia can be compared to the workers at the electric company who make sure wires go to the right places, maintain the wires, and take down wires that are broken. Although glia have been compared to workers, recent evidence suggests that also usurp some of the signaling functions of neurons. There is great diversity in the types of neurons and glia that are present in different parts of the nervous system. There are four major types of neurons, and they share several important cellular components. Answer: neurons

Output: The nervous system is made up of these?

Input: Consider Input: Passage: Chlamydia is the most common bacterial STI in the U. S. Females are more likely to develop it than males. Symptoms may include burning during urination and a discharge from the vagina or penis. Answer: chlamydia

Output: What is the most common bacterial sti in the u. s.?

Input: Consider Input: Passage: Sphenodontia Sphenodontia ("wedge tooth") arose in the Mesozoic era and includes only one living genus, Tuatara, comprising two species that are found in New Zealand (Figure 29.26). Tuataras measure up to 80 centimeters and weigh about 1 kilogram. Although quite lizard-like in gross appearance, several unique features of the skull and jaws clearly define them and distinguish the group from the squamates. Answer: living genus
Output: Sphenodontia sphenodontia ("wedge tooth") arose in the mesozoic era and includes only one of what?
