Ex Input:
He read the telegram again.  In desperation he went back to the long distance booth, but found the line still out of order, and a wire had come giving the details of the damage done by the storm.  It would be several days before communication could be established.  There was no help coming from headquarters, and from the wording of the telegram there seemed to be a reason for their not giving clear details.  He must get a copy of the paper.  Reluctantly he went to the printing office and made known his errand.  Mr. Driggs was delighted to give him the paper--he had it some place, though he very seldom opened any of his exchanges.  He evidently bore Mr. Steadman no ill-will for his plain talk two weeks ago.  With some difficulty he found it, with its wrapper still intact.  It was a loose wrapper, which slipped off and on easily.  Mr. Steadman remarked carelessly that there was an editorial in it to which his attention had been drawn, on hearing which Mr. Driggs turned his head and winked at an imaginary accomplice. <sep>What did Mr. Driggs still have intact around the item he was getting for Mr. Steadman?<sep>Box

No

Imagine a glass of your favorite drink that never became empty. Now think about what really happens. You take a drink and there is less in the glass. You keep drinking and soon it is all gone. Good thing you have more to refill your glass. What if there would never be any more of your favorite drink. What would you do? Now you know the difference between renewable and non-renewable. Its too bad that many things here on Earth will run out. This includes some of our natural resources we depend on. Things like oil will not last forever. There is a limited supply. Someday, we will run out, so then what? At current rates of use, coal will last about 300 years. Petroleum will be used up in just a few decades. <sep>What is the difference between renewable and non-renewable?<sep>Renewable resources can be "refilled." Once you run out of a non-renewable resource, there is no more of it
