"Writer Wallace Stegner said, 'National parks are the best idea we ever had. Absolutely American, absolutely democratic, they reflect us at our best rather than our worst.' By setting aside land for its natural beauty, and not merely for the monetary worth of its resources, we preserve a part of our shared heritage in our land. By making sure historical sites are preserved, we elevate the importance of them, educate our citizens, and ensure that they will remain for generations to come. When these parks are protected so that all people have the ability to visit them--not just the wealthy and well-connected--we underscore the democratic principles of our nation. The staff of the National Parks Service cares for our national parks, and they need resources in order to maintain and protect these special spaces. It is important to safeguard our national parks in order to conserve the natural habitats present there, as well as to preserve the ideals that national parks stand for: natural beauty, citizenship, and democracy." What is the implied main idea?

National parks are American treasures and should remain protected.

Preserving the natural resources in America's national parks is the main reason they should be conserved.

American national parks are either set aside for natural beauty or for their historical significance.

in a place once known as north america, now known as panem, is a very rich city surrounded by twelve districts. every year because this very rich city, known as the capitol, is so rich and likes to think they control all the districts - which they do - there is something known as the hunger games! this is where two children, one boy and one girl from each district from the ages of twelve to eighteen, have to leave their families and compete in the hunger games, a live event that is aired on tv's all over panem. when katniss everdeen, aged sixteen from district 12, has to volunteer to take the place of her twelve-year-old sister prim after prim's name is called forth to become the 23rd member to compete in the 74th hunger games, she promises to prim that she will win! katniss doesn't believe she's coming out alive - but she's not going down without a fight.

because district 12 is so poor, katniss has been close to death many times from starvation but she's made it through it. but this is a different kind of close to death; this katniss doesn't know if she can survive.

she doesn't want to hurt, or kill anyone but when it comes down to it katniss' instinct is to survive. but when she starts to have confusing feelings about the boy from her district who is also her fellow contender, things get worse, and then she teams up with the girl from district 11 and only one person can survive. but who will it be? will her feelings get the better of her? will she let someone else win so they don't have to die? if katniss is going to win she's going to have to be brutal. she's going to have to kill!

i decided to stay late in the laboratory to continue my experiment with the lightbulb. at midnight, thomas edison opened the door and saw all the stuff he was working on. the lightbulb, film and the transmitter. as he walks in an idea hits him on how the lightbulb would work. he would have to change a few wires around to get it to light up. when he did change the wires around it worked so he decided to write a telegraph to his friend to tell him about his success.   as he was packing up he grabbed the telegraph and walked to his home. he told his wife about the success and the next morning mailed the telegraph.

the purpose is to inform because for some reason they really want you to know about it.
