Teacher: Given a scientific passage and an answer, generate a question for the given answer.
Teacher: Now, understand the problem? If you are still confused, see the following example:
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.
Solution: A frameshift mutation is a deletion or insertion of one or more of what that changes the reading frame of the base sequence?
Reason: The science passage defines frame mutation and the main compoment here is nucleotides. Hence the generated question is apt.

Now, solve this instance: Passage: Electrochemistry is the study of chemical processes that occur at the interface between an electron conductor, such as a wire, and a solution of electrolytes, which is often simply an ionic substance dissolved in water. Electrochemical processes involve a transfer of electrons between the wire and the solution. These reactions can be used to create electrical power, to purify metals, and to carry out a number of useful chemical transformations. Answer: electrochemical
Student:
What processes involve a transfer of electrons between the wire and the solution?
