Teacher:In this task, you need to write an incorrect answer to the given question. Along with the question, you are also given the correct answer(s) and the associated paragraph. An incorrect answer should be closely related to the content of the paragraph and/or the question but will not truthfully answer the question. Your incorrect answers should be similar to the given correct answer such that it will pose a challenge for students to distinguish the two. A good incorrect answer should prevent those who skip the paragraph from answering the question. The incorrect answer should not be trivial, in the sense that they should not be easily eliminated without reading the paragraph.
Teacher: Now, understand the problem? Solve this instance: Paragraph- Sent 1: Surely, you have noticed the tall poles along the roadside.
Sent 2: Do you know what is on top of those poles?
Sent 3: Thats right, wires that carry electric current.
Sent 4: These wires carry electric current to your home.
Sent 5: But what is electric current?
Sent 6: Electric current is actually the flow of electrons.
Sent 7: You may recall, an electron is the outer-most particle in an atom.
Sent 8: They have a negative charge.
Sent 9: Electricity is the continuous flow of these particles.
Sent 10: Electrons are able to move through wires.
Sent 11: Their speed can even be measured.
Sent 12: The SI unit for electric current (or speed) is the ampere (A).
Sent 13: Ampere is often shortened to amp.
Sent 14: Electric current may flow in just one direction, or it may keep reversing direction.
Sent 15: Direct current (DC) flows in only one direction.
Sent 16: Direct current is what is used in devices like flashlights.
Sent 17: Alternating current (AC) flows in two directions.
Sent 18: This is the type of current that flows into your home through wires. 
Question: What are two types of electric current?.
Student:
Electrons and protons.
