Sent 4: How will you do this?
Sent 5: You sort them by size and shape until they are each back into their specific place in the tray.
Sent 6: What do you think you could have called the mess your younger sister created?
Sent 7: Thats right, it is a mixture.
Sent 8: Fortunately, it was a physical change and she just made a simple mixture.
Sent 9: You are able to separate them back into order.
Sent 10: Its a good thing she did not toss them into the fireplace.
Sent 11: That would have caused a chemical change as they all melted together.
Sent 12: If your LEGOs were melted, you would be out of luck for building that next big project.

Paragraph- Sent 1: Animated history of the US.
Sent 2: Of course the cartoon is highly oversimplified, and most critics consider it one of the weakest parts of the film.
Sent 3: But it makes a valid claim which you ignore entirely: That the strategy to promote "gun rights" for white people and to outlaw gun possession by black people was a way to uphold racism without letting an openly terrorist organization like the KKK flourish.
Sent 4: Did the 19th century NRA in the southern states promote gun rights for black people?
Sent 5: I highly doubt it.
Sent 6: But if they didn't, one of their functions was to continue the racism of the KKK.
Sent 7: This is the key message of this part of the animation, which is again being ignored by its critics.
Sent 8: Buell shooting in Flint.
Sent 9: You write: "Fact: The little boy was the class thug, already suspended from school for stabbing another kid with a pencil, and had fought with Kayla the day before".
Sent 10: This characterization of a six-year-old as a pencil-stabbing thug is exactly the kind of hysteria that Moore's film warns against.
Sent 11: It is the typical right-wing reaction which looks for simple answers that do not contradict the Republican mindset.
Sent 12: The kid was a little bastard, and the parents were involved in drugs -- case closed.
Sent 13: But why do people deal with drugs?
Sent 14: Because it's so much fun to do so?
Sent 15: It is by now well documented that the CIA tolerated crack sales in US cities to fund the operation of South American "contras" It is equally well known that the so-called "war on drugs" begun under the Nixon administration is a failure which has cost hundreds of billions and made America the world leader in prison population (both in relative and absolute numbers).
Question: How old was the little boy who had fought Kayla? (A) 9 years old (B) 8 years old (C) 6 years old (D) 6th grade (E) 7 years old (F) Six.
C, F.

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.
B.
