European and American scientific teams have been studying ice from the same area to confirm each other's findings. They measured the oxygen and carbon dioxide in the ice for the temperature. From these measurements, the scientific teams say that the past 10,000 years is the only period during which temperature has not changed very much.
According to the news, ice from Greenland gives information about
A.oxygen.
B.ancient weather.
C.carbon dioxide.
D.temperature.

I took his hand as gently as he had once taken mine. "Hello, Grandpa," I whispered. His eyes slowly opened. "Hello, my friend," he said, with a brief smile. His eyes closed again and I moved on. I was standing by his rosebush when an uncle came to tell me that my grandfather had died. Remembering Grandpa's words, I reached deep within me for those special feelings that had made up our friendship. Suddenly, and truly, I knew what he had meant about never saying goodbye --- about refusing to give in to the sadness.
Scientists took the ice from more than 1.5 -mile deep in huge masses of ice that float on the sea. The ice represents 25,000 years of history. It provides one of the clearest records of ancient weather.
