PROBLEM: 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.

SOLUTION: B.

PROBLEM: Paragraph- Sent 1: As his car slid downtown on Tuesday morning the mind of Arnold Thorndike was occupied with such details of daily routine as the purchase of a railroad, the Japanese loan, the new wing to his art gallery, and an attack that morning, in his own newspaper, upon his pet trust.
Sent 2: But his busy mind was not too occupied to return the salutes of the traffic policemen who cleared the way for him.
Sent 3: Or, by some genius of memory, to recall the fact that it was on this morning young Spear was to be sentenced for theft.
Sent 4: It was a charming morning.

Sent 10: But that, on the part of a stenographer, in the presence of the Wisest Man in Wall Street, was not unnatural.
Sent 11: On occasions, Mr. Thorndike had put even royalty frayed, impecunious royalty, on the lookout for a loanat its ease.
Sent 12: The hood of the car was down, and the taste of the air, warmed by the sun, was grateful.

Sent 15: It was characteristic of the great man to act quickly, so quickly that his friends declared he was a slave to impulse.

Sent 17: He leaned forward and touched the chauffeur's shoulder.
Sent 18: "Stop at the Court of General Sessions," he commanded.
