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 (", ").

[EX Q]: Paragraph- Sent 1: Breathing is the process of moving air into and out of the lungs.
Sent 2: The process depends on a muscle called the diaphragm.
Sent 3: This is a large, sheet-like muscle below the lungs.
Sent 4: Inhaling, or breathing in, occurs when the diaphragm muscle tightens.
Sent 5: This increases the size of the chest.
Sent 6: This too decreases air pressure inside the lungs.
Sent 7: This action allows air and gases to enter the lungs.
Sent 8: Exhaling, or breathing out, occurs when the diaphragm muscle relaxes.
Sent 9: This decreases the size of the chest.
Sent 10: This increases air pressure inside the lungs.
Sent 11: This action allows for air to leave the lungs.
Sent 12: When you inhale, air enters the respiratory system through your nose and ends up in your lungs, where gas exchange with the blood takes place.
Sent 13: What happens to the air along the way?
Sent 14: In the nose, mucus and hairs trap any dust or other particles in the air.
Sent 15: The air is also warmed and moistened.
Sent 16: Next, air passes through a passageway that is connected to the windpipe.
Sent 17: The air then finds its way to the lungs.
Sent 18: In the chest, the windpipe splits so that air enters both the right and left lung.
Question: What happens to the air pressure inside your lungs when you inhale?.

Sent 16: On the advice of the principal of the Polytechnic, he attended the Argovian cantonal school (gymnasium) in Aarau, Switzerland, in 1895-96 to complete his secondary schooling.
