[EX Q]: Paragraph- Sent 1: Rough surfaces create more friction than smooth surfaces.
Sent 2: Thats why cars have tires.
Sent 3: Its also why we use rubber mats in areas that might get wet.

Sent 5: No-slip is another way of saying the items has a lot of friction.
Sent 6: In Figure 1.9, the blades of the skates are very smooth.
Sent 7: Thats why you cant slide across ice with shoes.
Sent 8: The soles of your shoes are much rougher than skates.
Sent 9: The rougher surface of shoes causes more friction and slows you down.
Sent 10: Heavier objects also have more friction.
Sent 11: A heavy object presses down with more force.
Sent 12: The surfaces are held together more tightly.
Sent 13: This makes the surfaces harder to slide past each other.
Sent 14: Did you ever try to push something heavy across the floor?
Sent 15: Heavy objects are much harder to push than light objects.
Question: Why do heavier objects have more friction? (A) A heavy object presses down with more force. The surfaces are held together more tightly, making the surfaces harder to slide past each other (B) Held down with more force to a surface which holds them together more tightly (C) Weight has invese relation with friction (D) Dresser.
[EX A]: A, B.

[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 is the muscle called that tightens and relaxes, allowing you to breathe? (A) Chest (B) Diaphragm (C) Biceps.
[EX A]: B.
