Task: Given a scientific passage and an answer, generate a question for the given answer.
Categories: Question Generation
Domains: Natural Science -> School Science Textbooks
Reasoning: Scientific Reasoning

Positive examples:
input: Passage: A frameshift mutation is a deletion or insertion of one or more nucleotides that changes the reading frame of the base sequence. Deletions remove nucleotides, and insertions add nucleotides. Consider the following sequence of bases in RNA:. Answer: nucleotides.
output: A frameshift mutation is a deletion or insertion of one or more of what that changes the reading frame of the base sequence?
explanation: The science passage defines frame mutation and the main compoment here is nucleotides. Hence the generated question is apt.; input: Passage: During telophase , the chromosomes begin to uncoil and form chromatin. This prepares the genetic material for directing the metabolic activities of the new cells. The spindle also breaks down, and new nuclear membranes form. Answer: chromatin
output: During telophase , the chromosomes begin to uncoil and form what?
explanation: Here the answer is chromatin and the question regarding its formation is present in the passage. Hence it is a correct question.

Negative examples:
input: Science Passage': '6.3 |  By the end of this section, you will be able to: • Discuss the concept of entropy • Explain the first and second laws of thermodynamics Thermodynamics refers to the study of energy and energy transfer involving physical matter. The matter and its environment relevant to a particular case of energy transfer are classified as a system, and everything outside of that system is called the surroundings. For instance, when heating a pot of water on the stove, the system includes the stove, the pot, and the water. Energy is transferred within the system (between the stove, pot, and water). There are two types of systems: open and closed. An open system is one in which energy can be transferred between the system and its surroundings. The stovetop system is open because heat can be lost into the air. A closed system is one that cannot transfer energy to its surroundings. Biological organisms are open systems. Energy is exchanged between them and their surroundings, as they consume energystoring molecules and release energy to the environment by doing work. Like all things in the physical world, energy is subject to the laws of physics. The laws of thermodynamics govern the transfer of energy in and among all systems in the universe. Answer: thermodynamics
output: What is called an open system ?
explanation: Although the question is valid and answer is present in the passage, it does not relate to the answer: thermodynamics.; input: Passage: Chemical reactivity trends are easy to predict when replacing anions in simple ionic compounds—simply use their relative positions on the periodic table. However, when replacing the cations, the trends are not as straightforward. This is partly because there are so many elements that can form cations; an element in one column on the periodic table may replace another element nearby, or it may not. A list called the activity series does the same thing the periodic table does for halogens: it lists the elements that will replace elements below them in single-replacement reactions. A simple activity series is shown below. Answer: activity series
output: Who invented windmill ?
explanation: The question is valid but neither the answer nor the passage is related to the question.
