TASK DEFINITION: You are given a paragraph, with numbered sentences, and a question. Write the numbers of the sentences needed to answer the given question. Separate multiple sentence numbers with a comma (", "). E.g. "1, 2" would be the correct response if Sent 1 and Sent 2 are needed to answer the given question (do not include sentences that contain no information that is necessary to answer the question). Sort the sentence numbers in an increasing order (i.e., '1, 2', instead of '2, 1'). Your answer should not contain anything than the sentence numbers separated by a comma (e.g. '1, 2, 3, 4'). The given question requires more than one sentence to answer. So, your answer must contain at least one comma (", ").
PROBLEM: Paragraph- Sent 1: The world can be divided into three climate zones.
Sent 2: The first climate zone is the polar zone.
Sent 3: As it sounds, the polar zone is near earths poles.
Sent 4: The polar zone has very long and cold winters.
Sent 5: Brrr!!!!
Sent 6: Near the equator is the tropical zone.
Sent 7: The tropical zone is known for being hot and wet.
Sent 8: Between these two zones is the temperate zone.
Sent 9: Temperatures there tend to be mild.
Sent 10: Its not too hot and not too cold.
Sent 11: You might expect places near the equator to be hot and wet.
Sent 12: Thats not always the case.
Sent 13: Sometimes there are other factors at work.
Sent 14: These factors can affect the local climate type or a region.
Sent 15: Oceans and mountain ranges can have a major impact.
Sent 16: They can greatly influence the climate of an area.
Sent 17: Many factors influence an areas climate.
Question: Which of the 3 climate zones is near the earths poles?.

SOLUTION: 1, 3.

PROBLEM: Paragraph- Sent 1: She led the way into the cheerful schoolroom, where big girls and little girls were sitting about, amusing themselves in the quiet of a long Sunday afternoon.
Sent 2: Several of the younger children ran to her as she came in, and stood holding fast to the folds of her black habit, staring up at the strangers, while she explained the kind of instruction given, the system, and the order reigning in each department.
Sent 3: Finally, she persuaded a little girl, only six years old, to take her dusky face out of the long flowing veil of the nun, and show how quickly she could read a sentence that Sister Winifred wrote on the blackboard.
Sent 4: Then others were called on, and gave examples of their accomplishments in easy arithmetic and spelling.
Sent 5: The children must have been very much bored with themselves that stormy Sunday, for they entered into the examination with a quite unnatural zest.
Sent 6: Two of the elder girls recited, and some specimens of penmanship and composition were shown.
Sent 7: The delicate complexion of the little nun flushed to a pretty wild-rose pink as these pupils of hers won the Colonel's old fashioned compliments.
Question: Are these students equal in age?.

SOLUTION: 2, 5, 6.

PROBLEM: Paragraph- Sent 1: Electric charge is a physical property.
Sent 2: It occurs between particles or objects.
Sent 3: It causes them to attract or repel each other.
Sent 4: They do not even have to touch.
Sent 5: This is unlike the typical push or pull you may be familiar with.
Sent 6: All electric charge is based on the protons and electrons in atoms.
Sent 7: A proton has a positive electric charge.
Sent 8: An electron has a negative electric charge (see Figure below).
Sent 9: Forces on Charged Objects Most atoms are balanced electrically.
Sent 10: They have the same number of positive and negative charges.
Sent 11: Therefore, the number of protons equals the number of electrons.
Sent 12: Neutrons do not matter as they have no charge.
Sent 13: When an object loses some electrons, it becomes positively charged.
Sent 14: There are now more protons than electrons inside the atom.
Sent 15: The lost electrons may remain free.
Sent 16: Or, they may attach to another object.
Sent 17: The new object now has more electrons than protons.
Sent 18: It then becomes negatively charged.
Question: Why does an objects charge become negative?.

SOLUTION:
7, 10, 11, 17.
