Q: Paragraph- Sent 1: Gravitational Potential Energy is affected by position.
Sent 2: Like the leaves on trees, anything that is raised up has the potential to fall.
Sent 3: It has potential energy.
Sent 4: You can see examples of people with gravitational potential energy in 1.5 Figure below.
Sent 5: Gravitational potential energy depends on two things.
Sent 6: It depends on its weight, because a large falling rock can do more damage than a leaf falling from a tree.
Sent 7: It also depends on its height above the ground.
Sent 8: Like the skateboarder, the higher the ramp, the faster he will be going when he reaches the bottom.
Sent 9: Like all energy, gravitational potential energy has the ability to do work.
Sent 10: In this case, weight has the potential to deliver a force.
Sent 11: More important for us is that it has the ability to cause change.
Sent 12: What kind of change you may ask?
Sent 13: Gravitational potential energy has the ability to cause motion.
Question: What is the most important change gravitational potential energy can have? (A) The ability to cause motion (B) Motion (C) Friction (D) Deliver make skateboarders move.

A: A, B.

Q: Paragraph- Sent 1: "What goes up must come down."Sent 2: You have probably heard that statement before.
Sent 3: At one time this statement was true, but no longer.
Sent 4: Since the 1960s, we have sent many spacecraft into space.
Sent 5: Some are still traveling away from Earth.
Sent 6: So it is possible to overcome gravity.
Sent 7: Do you need a giant rocket to overcome gravity?
Sent 8: No, you actually overcome gravity every day.
Sent 9: Think about when you climb a set of stairs.
Sent 10: When you do, you are overcoming gravity.
Sent 11: What if you jump on a trampoline?
Sent 12: You are overcoming gravity for a few seconds.
Sent 13: Everyone can overcome gravity.
Sent 14: You just need to apply a force larger than gravity.
Sent 15: Think about that the next time you jump into the air.
Sent 16: You are overcoming gravity for a brief second.
Sent 17: Enjoy it while it lasts.
Sent 18: Eventually, gravity will win the battle.
Question: Can a person overcome gravity? (A) Never (B) It is possible (C) Yes, by jumping up into the air or climbing stairs.

A: B, C.

Q: 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 5: The spring was at full tide, and the air was sweet and clean.
Sent 6: Mr. Thorndike considered whimsically that to send a man to jail with the memory of such a morning clinging to him was adding a year to his sentence.
Sent 7: He regretted he had not given the probation officer a stronger letter.
Sent 8: He remembered the young man now, and favorably.
Sent 9: A shy, silent youth, deft in work, and at other times conscious and embarrassed.
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 13: It was at this time, a year before, that young Spear picked the spring flowers to take to his mother.
Sent 14: A year from now where would young Spear be?
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 16: It was these same impulses, leading so invariably to success, that made his enemies call him the Wisest Man.
Sent 17: He leaned forward and touched the chauffeur's shoulder.
Sent 18: "Stop at the Court of General Sessions," he commanded.
Sent 19: What he proposed to do would take but a few minutes.
Sent 20: A word, a personal word from him to the district attorney, or the judge, would be enough.
Question: What is the name of the shy, silent stenographer about to be put in jail for theft? (A) Spear (B) Arnold (C) Thorndike (D) The probation officer.

A:
A.
