Questions 46-50 are based on the following passage.

Icebergs2 are among nature's most spectacular creations, and yet most people have never seen one. A vague air of mystery envelops3 them. They come into being-somewhere-in faraway, line frigid4 waters, amid thunderous noise and splashing turbulence5, which in most cases no one hears or sees. They exist only a short time and then slowly away just as unnoticed.
Objects of sheerest beauty, they have been called. Appearing  variety of shapes, they may be dazzlingly white, or they may be glassy blue, green, or purple, tinted6 faintly or in darker hues7. They are graceful8, stately, inspiring-in calm, sunlit seas.
But they are also called frightening and dangerous, and that they are in the night, in the fog, and in storms. Even in clear weather one is wise to stay at a safe distance away from them. Most of their bilk is hidden below the visible top. Also, they may roll over unexpectedly, churning the waters around them.
Icebergs are parts of glaciers9 that break off, drift into the water, float about a while, and finally melt. Iceberg1 afloat today are made of anowflakes that have fallen over long ages of time. They embody10 snows that drifted down hundreds, or many thousands, or in some cases maybe a million year ago. The snows fel l in polar regions and on cold mountains, where they melted only a little or not at all, and so collected to great depths over the years and centuries.
As each year's snow accumulation lay on the surface, evaporation11 and melting caused the snowflakes slowly fell on the top of the old, it too turned to icy grains. So blankets of snow and ice grains mounted layer upon layer and were of such great thickness that the weight of the upper layers compressed the lower ones. With time and pressure from above, the many small ice grains joined and changed to larger crystals, and eventually the deeper crystals merged12 into a solid mass of ice.
