Close Test 2

      First there was ice. Then there was the refrigerator. Then the freezer which is fine for       1      things a long time was developed, but it destroys the flavor of food. An amazing new technique for      2          the freshness and natural flavor of meats and fish has been discovered after thousands of years of man’s first attempts to keep       3        fresh by lowering temperature. This is amazing because this revolutionary technique keeps food     4         twice as long.
       This method of       5          came about in a fascinating experiment that scientists in Japan performed with a crab. Under laboratory conditions, they put a live crab in a compartment at a     6        just below the freezing point. Five months     7       , they returned the crab to normal temperatures and it       8          from its sleep.
       Later, they put a rose into a two-month-long sleep by chilling it and the flower emerged as beautiful and fresh as if it were     9        packed.
       Both of these      10        proved that the special temperature just below the freezing point could keep organic matter fresh without destroying it.
