[EX Q]: Paragraph- Sent 1: An atom is the very smallest particle that still the elements properties.
Sent 2: All the atoms of an element are alike.
Sent 3: They are also different from the atoms of all other elements.
Sent 4: For example, atoms of gold are always the same.
Sent 5: It does not matter if they are found in a gold nugget or a gold ring.
Sent 6: All gold atoms have the same structure and properties.
Sent 7: For example, all gold atoms contain 79 protons.
Sent 8: One of golds unique properties is that it is a great conductor of electricity.
Sent 9: Gold is a better conductor of electricity than copper.
Sent 10: Gold is more rare and expensive than copper.
Sent 11: Copper is used in house wiring.
Sent 12: Gold is far too expensive.
Question: What are the major differences between Gold and Copper?.
[EX A]: Gold is a better conductor and more rare and expensive than Copper.

[EX Q]: Paragraph- Sent 1: Johnnie had a set of small volumes of English verse, extensively annotated by his own hand, which Stoddard had brought to her early in their acquaintance, leaving it with her more as a gift than as a loan.
Sent 2: She kept these little books after all the others had gone back.
Sent 3: She had read and reread them--cullings from Chaucer, from Spenser, from the Elizabethan lyrists, the border balladry, fierce, tender, oh, so human--till she knew pages of them by heart, and their vocabulary influenced her own, their imagery tinged all her leisure thoughts.
Sent 4: It seemed to her, whenever she debated returning them, that she could not bear it.
Sent 5: She would get them out and sit with one of them open in her hands, not reading, but staring at the pages with unseeing eyes, passing her fingers over it, as one strokes a beloved hand, or turning through each book only to find the pencilled words in the margins.
Sent 6: She would be giving up part of herself when she took these back.
Sent 7: Yet it had to be done, and one miserable morning she made them all into a neat package, intending to carry them to the mill and place them on Stoddard's desk thus early, when nobody would be in the office.
Sent 8: Then the children came in; Deanie was half sick; and in the distress of getting the ailing child comfortably into her own bed, Johnnie forgot the books.
Sent 9: Taking them in at noon, she met Stoddard himself.
Question: Did the main character originally keep stories by Chaucer after the others had all gone back?.
[EX A]: Yes.

[EX Q]: 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?.
[EX A]:
AC and DC.
